Behaviour

  1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
  2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
  3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
  4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

Notice that the proxy also provides a number of useful endpoints.

Version: 6.1.x

Overview

oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

To generate a strong cookie secret use one of the below commands:

python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

Config File​

Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

When combined with --reverse-proxy and optionally --real-client-ip-header this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

Environment variables​

Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

Configuring for use with the Nginx auth_request directive​

The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

server {
  listen 443 ssl;
  server_name ...;
  include ssl/ssl.conf;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;

    proxy_set_header X-Auth-Request-Redirect $request_uri;
    # or, if you are handling multiple domains:
    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
  }
  location = /oauth2/auth {

    proxy_set_header Content-Length   "";
    proxy_pass_request_body           off;
  }

  location / {
    auth_request /oauth2/auth;
    error_page 401 = /oauth2/sign_in;

    # pass information via X-User and X-Email headers to backend,
    # requires running with --set-xauthrequest flag
    auth_request_set $user   $upstream_http_x_auth_request_user;

    # limit and so the OAuth2 Proxy splits these into multiple parts.
    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;

    # Extract the Cookie attributes from the first Set-Cookie header and append them
    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
    if ($auth_cookie ~* "(; .*)") {
        set $auth_cookie_name_0 $auth_cookie;
        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
    }

    # Send both Set-Cookie headers now if there was a second part
    if ($auth_cookie_name_upstream_1) {
        add_header Set-Cookie $auth_cookie_name_0;
        add_header Set-Cookie $auth_cookie_name_1;
    }

    proxy_pass http://backend/;
    # or "root /path/to/site;" or "fastcgi_pass ..." etc
  }
}

When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
  auth_request_set $name_upstream_1 $upstream_cookie_name_1;

  access_by_lua_block {
    if ngx.var.name_upstream_1 ~= "" then
      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
    end
  }

It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

note

If you set up your OAuth2 provider to rotate your client secret, you can use the client-secret-file option to reload the secret when it is updated.

Endpoints

OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

  • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
  • /ping - returns a 200 OK response, which is intended for use with health checks
  • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
  • /oauth2/sign_out - this URL is used to clear the session cookie
  • /oauth2/start - a URL that will redirect to start the OAuth cycle
  • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
  • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
  • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

Sign out​

To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

GET /oauth2/sign_out HTTP/1.1
X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
...

(The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored.

Behaviour

  1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
  2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
  3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
  4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

Notice that the proxy also provides a number of useful endpoints.

pathstringPath is used to map requests to the upstream server.
The closest match will take precedence and all Paths must be unique.
uristringThe URI of the upstream server. This may be an HTTP(S) server of a File
based URL. It may include a path, in which case all requests will be served
under that path.
Eg:
- http://localhost:8080
- https://service.localhost
- https://service.localhost/path
- file://host/path
If the URI's path is "/base" and the incoming request was for "/dir",
the upstream request will be for "/base/dir".
insecureSkipTLSVerifyboolInsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.
This option is insecure and will allow potential Man-In-The-Middle attacks
betweem OAuth2 Proxy and the usptream server.
Defaults to false.
staticboolStatic will make all requests to this upstream have a static response.
The response will have a body of "Authenticated" and a response code
matching StaticCode.
If StaticCode is not set, the response will return a 200 response.
staticCodeintStaticCode determines the response code for the Static response.
This option can only be used with Static enabled.
flushIntervalDurationFlushInterval is the period between flushing the response buffer when
streaming response from the upstream.
Defaults to 1 second.
passHostHeaderboolPassHostHeader determines whether the request host header should be proxied
to the upstream server.
Defaults to true.
proxyWebSocketsboolProxyWebSockets enables proxying of websockets to upstream servers
Defaults to true.

Version: 7.0.x

Overview

oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

To generate a strong cookie secret use one of the below commands:

python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

Config File​

Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

Environment variables​

Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

This is particularly useful for storing secrets outside of a configuration file @@ -20,7 +20,7 @@ The default format is configured as follows:

Configuring for use with the Nginx auth_request directive​

The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

server {
  listen 443 ssl;
  server_name ...;
  include ssl/ssl.conf;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;

When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
  auth_request_set $name_upstream_1 $upstream_cookie_name_1;

  access_by_lua_block {
    if ngx.var.name_upstream_1 ~= "" then
      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
    end
  }

It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

Configuring for use with the Traefik (v2) ForwardAuth middleware​

Endpoints

OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

  • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
  • /ping - returns a 200 OK response, which is intended for use with health checks
  • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
  • /oauth2/sign_out - this URL is used to clear the session cookie
  • /oauth2/start - a URL that will redirect to start the OAuth cycle
  • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
  • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
  • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

Sign out​

To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

GET /oauth2/sign_out HTTP/1.1
X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
...

(The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored.

Behaviour

  1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
  2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
  3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
  4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

Notice that the proxy also provides a number of useful endpoints.

TLSTLSTLS contains the information for loading the certificate and key for the
secure traffic.

TLS​

(Appears on: Server)

TLS contains the information for loading a TLS certifcate and key.

FieldTypeDescription
KeySecretSourceKey is the TLS key data to use.
Typically this will come from a file.
CertSecretSourceCert is the TLS certificate data to use.
Typically this will come from a file.

Upstream​

(Appears on: Upstreams)

Upstream represents the configuration for an upstream server. Requests will be proxied to this upstream if the path matches the request path.

FieldTypeDescription
idstringID should be a unique identifier for the upstream.
This value is required for all upstreams.
pathstringPath is used to map requests to the upstream server.
The closest match will take precedence and all Paths must be unique.
uristringThe URI of the upstream server. This may be an HTTP(S) server of a File
based URL. It may include a path, in which case all requests will be served
under that path.
Eg:
- http://localhost:8080
- https://service.localhost
- https://service.localhost/path
- file://host/path
If the URI's path is "/base" and the incoming request was for "/dir",
the upstream request will be for "/base/dir".
insecureSkipTLSVerifyboolInsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.
This option is insecure and will allow potential Man-In-The-Middle attacks
betweem OAuth2 Proxy and the usptream server.
Defaults to false.
staticboolStatic will make all requests to this upstream have a static response.
The response will have a body of "Authenticated" and a response code
matching StaticCode.
If StaticCode is not set, the response will return a 200 response.
staticCodeintStaticCode determines the response code for the Static response.
This option can only be used with Static enabled.
flushIntervalDurationFlushInterval is the period between flushing the response buffer when
streaming response from the upstream.
Defaults to 1 second.
passHostHeaderboolPassHostHeader determines whether the request host header should be proxied
to the upstream server.
Defaults to true.
proxyWebSocketsboolProxyWebSockets enables proxying of websockets to upstream servers
Defaults to true.

Overview

oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

To generate a strong cookie secret use python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

Config File​

Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

When combined with --reverse-proxy and optionally --real-client-ip-header this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

Environment variables​

Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

Configuring for use with the Nginx auth_request directive​

The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

server {
  listen 443 ssl;
  server_name ...;
  include ssl/ssl.conf;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;

    # or, if you are handling multiple domains:
    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;

When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
  auth_request_set $name_upstream_1 $upstream_cookie_name_1;

  access_by_lua_block {
    if ngx.var.name_upstream_1 ~= "" then
      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
    end
  }

It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

Configuring for use with the Traefik (v2) ForwardAuth middleware​

This option requires --reverse-proxy option to be set.

ForwardAuth with 401 errors middleware​

The Traefik v2 ForwardAuth middleware allows Traefik to authenticate requests via the oauth2-proxy's /oauth2/auth endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through.

Endpoints

OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

  • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
  • /ping - returns a 200 OK response, which is intended for use with health checks
  • /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by --metrics-address, disabled by default
  • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
  • /oauth2/sign_out - this URL is used to clear the session cookie
  • /oauth2/start - a URL that will redirect to start the OAuth cycle
  • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
  • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
  • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

Sign out​

To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

GET /oauth2/sign_out HTTP/1.1
X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
...

(The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored.

Behaviour

  1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
  2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
  3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
  4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

Notice that the proxy also provides a number of useful endpoints.

This value is required for all upstreams.
pathstringPath is used to map requests to the upstream server.
The closest match will take precedence and all Paths must be unique.
Path can also take a pattern when used with RewriteTarget.
Path segments can be captured and matched using regular experessions.
Eg:
- ^/foo$: Match only the explicit path /foo
- ^/bar/$: Match any path prefixed with /bar/
- ^/baz/(.*)$: Match any path prefixed with /baz and capture the remaining path for use with RewriteTarget
rewriteTargetstringRewriteTarget allows users to rewrite the request path before it is sent to
the upstream server.
Use the Path to capture segments for reuse within the rewrite target.
Eg: With a Path of ^/baz/(.*), a RewriteTarget of /foo/$1 would rewrite
the request /baz/abc/123 to /foo/abc/123 before proxying to the
upstream server.
uristringThe URI of the upstream server. This may be an HTTP(S) server of a File

under that path.
Eg:
- http://localhost:8080
- https://service.localhost
- https://service.localhost/path
- file://host/path
If the URI's path is "/base" and the incoming request was for "/dir",
the upstream request will be for "/base/dir".

Overview

oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

To generate a strong cookie secret use one of the below commands:

python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

Config File​

Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

Environment variables​

Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

This is particularly useful for storing secrets outside of a configuration file @@ -20,7 +20,7 @@ The default format is configured as follows:

{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}

Standard Log Format​

All other logging that is not covered by the above two types of logging will be output in this standard logging format. This includes configuration information at startup and errors that occur outside of a session. The default format is below:

[19/Mar/2015:17:20:19 -0400] [main.go:40] <MESSAGE>

If you require a different format than that, you can configure it with the --standard-logging-format flag. The default format is configured as follows:

[{{.Timestamp}}] [{{.File}}] {{.Message}}

Available variables for standard logging:

VariableExampleDescription
Timestamp19/Mar/2015:17:20:19 -0400The date and time of the logging event.
Filemain.go:40The file and line number of the logging statement.
MessageHTTP: listening on 127.0.0.1:4180The details of the log statement.

Configuring for use with the Nginx auth_request directive​

The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

server {
  listen 443 ssl;
  server_name ...;
  include ssl/ssl.conf;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host                    $host;
    proxy_set_header X-Real-IP               $remote_addr;
    proxy_set_header X-Scheme                $scheme;
    proxy_set_header X-Auth-Request-Redirect $request_uri;
    # or, if you are handling multiple domains:
    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
  }
  location = /oauth2/auth {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host             $host;
    proxy_set_header X-Real-IP        $remote_addr;

    # nginx auth_request includes headers but not body
    proxy_set_header Content-Length   "";
    proxy_pass_request_body           off;
  }

  location / {
    auth_request /oauth2/auth;
    error_page 401 = /oauth2/sign_in;

    # pass information via X-User and X-Email headers to backend,
    # requires running with --set-xauthrequest flag
    auth_request_set $user   $upstream_http_x_auth_request_user;
    auth_request_set $email  $upstream_http_x_auth_request_email;
    proxy_set_header X-User  $user;
    proxy_set_header X-Email $email;

    # if you enabled --pass-access-token, this will pass the token to the backend
    auth_request_set $token  $upstream_http_x_auth_request_access_token;
    proxy_set_header X-Access-Token $token;

    # if you enabled --cookie-refresh, this is needed for it to work with auth_request
    auth_request_set $auth_cookie $upstream_http_set_cookie;
    add_header Set-Cookie $auth_cookie;

    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
    # limit and so the OAuth2 Proxy splits these into multiple parts.
    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;

    # Extract the Cookie attributes from the first Set-Cookie header and append them
    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
    if ($auth_cookie ~* "(; .*)") {
        set $auth_cookie_name_0 $auth_cookie;
        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
    }

    # Send both Set-Cookie headers now if there was a second part
    if ($auth_cookie_name_upstream_1) {
        add_header Set-Cookie $auth_cookie_name_0;
        add_header Set-Cookie $auth_cookie_name_1;
    }

    proxy_pass http://backend/;
    # or "root /path/to/site;" or "fastcgi_pass ..." etc
  }
}

When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
  auth_request_set $name_upstream_1 $upstream_cookie_name_1;

  access_by_lua_block {
    if ngx.var.name_upstream_1 ~= "" then
      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
    end
  }

It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

Configuring for use with the Traefik (v2) ForwardAuth middleware​

This option requires --reverse-proxy option to be set.

ForwardAuth with 401 errors middleware​

The Traefik v2 ForwardAuth middleware allows Traefik to authenticate requests via the oauth2-proxy's /oauth2/auth endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through.

Endpoints

OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

  • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
  • /ping - returns a 200 OK response, which is intended for use with health checks
  • /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by --metrics-address, disabled by default
  • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
  • /oauth2/sign_out - this URL is used to clear the session cookie
  • /oauth2/start - a URL that will redirect to start the OAuth cycle
  • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
  • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
  • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

Sign out​

To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

GET /oauth2/sign_out HTTP/1.1
X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
...

(The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored.

Behaviour

  1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
  2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
  3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
  4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

Notice that the proxy also provides a number of useful endpoints.

Upstream​

(Appears on: UpstreamConfig)

Upstream represents the configuration for an upstream server. Requests will be proxied to this upstream if the path matches the request path.

FieldTypeDescription
idstringID should be a unique identifier for the upstream.
This value is required for all upstreams.
pathstringPath is used to map requests to the upstream server.
The closest match will take precedence and all Paths must be unique.
Path can also take a pattern when used with RewriteTarget.
Path segments can be captured and matched using regular experessions.
Eg:
- ^/foo$: Match only the explicit path /foo
- ^/bar/$: Match any path prefixed with /bar/
- ^/baz/(.*)$: Match any path prefixed with /baz and capture the remaining path for use with RewriteTarget
rewriteTargetstringRewriteTarget allows users to rewrite the request path before it is sent to
the upstream server.
Use the Path to capture segments for reuse within the rewrite target.
Eg: With a Path of ^/baz/(.*), a RewriteTarget of /foo/$1 would rewrite
the request /baz/abc/123 to /foo/abc/123 before proxying to the
upstream server.
uristringThe URI of the upstream server. This may be an HTTP(S) server of a File
based URL. It may include a path, in which case all requests will be served
under that path.
Eg:
- http://localhost:8080
- https://service.localhost
- https://service.localhost/path
- file://host/path
If the URI's path is "/base" and the incoming request was for "/dir",
the upstream request will be for "/base/dir".

Overview

oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

To generate a strong cookie secret use one of the below commands:

python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

Config File​

Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . or a *. will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

When combined with --reverse-proxy and optionally --real-client-ip-header this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

[1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

[2]: When using the whitelist-domain option, any domain prefixed with a . or a *. will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

See below for provider specific options

Upstreams Configuration​

oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

Environment variables​

Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

This is particularly useful for storing secrets outside of a configuration file @@ -20,7 +20,7 @@ The default format is configured as follows:

{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}

Available variables for request logging:

Standard Log Format​

All other logging that is not covered by the above two types of logging will be output in this standard logging format. This includes configuration information at startup and errors that occur outside of a session. The default format is below:

[19/Mar/2015:17:20:19 -0400] [main.go:40] <MESSAGE>

If you require a different format than that, you can configure it with the --standard-logging-format flag. The default format is configured as follows:

[{{.Timestamp}}] [{{.File}}] {{.Message}}

Available variables for standard logging:

VariableExampleDescription
Timestamp19/Mar/2015:17:20:19 -0400The date and time of the logging event.
Filemain.go:40The file and line number of the logging statement.
MessageHTTP: listening on 127.0.0.1:4180The details of the log statement.

Configuring for use with the Nginx auth_request directive​

The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

server {
  listen 443 ssl;
  server_name ...;
  include ssl/ssl.conf;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host                    $host;
    proxy_set_header X-Real-IP               $remote_addr;
    proxy_set_header X-Scheme                $scheme;
    proxy_set_header X-Auth-Request-Redirect $request_uri;
    # or, if you are handling multiple domains:
    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
  }
  location = /oauth2/auth {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host             $host;
    proxy_set_header X-Real-IP        $remote_addr;

    # nginx auth_request includes headers but not body
    proxy_set_header Content-Length   "";
    proxy_pass_request_body           off;
  }

  location / {
    auth_request /oauth2/auth;
    error_page 401 = /oauth2/sign_in;

    # pass information via X-User and X-Email headers to backend,
    # requires running with --set-xauthrequest flag
    auth_request_set $user   $upstream_http_x_auth_request_user;
    auth_request_set $email  $upstream_http_x_auth_request_email;
    proxy_set_header X-User  $user;
    proxy_set_header X-Email $email;

    # if you enabled --pass-access-token, this will pass the token to the backend
    auth_request_set $token  $upstream_http_x_auth_request_access_token;
    proxy_set_header X-Access-Token $token;

    # if you enabled --cookie-refresh, this is needed for it to work with auth_request

    add_header Set-Cookie $auth_cookie;

    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
    # limit and so the OAuth2 Proxy splits these into multiple parts.
    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;

    # Extract the Cookie attributes from the first Set-Cookie header and append them
    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
    if ($auth_cookie ~* "(; .*)") {
        set $auth_cookie_name_0 $auth_cookie;
        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
    }

    # Send both Set-Cookie headers now if there was a second part
    if ($auth_cookie_name_upstream_1) {
        add_header Set-Cookie $auth_cookie_name_0;
        add_header Set-Cookie $auth_cookie_name_1;
    }

    proxy_pass http://backend/;
    # or "root /path/to/site;" or "fastcgi_pass ..." etc
  }
}

When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
  auth_request_set $name_upstream_1 $upstream_cookie_name_1;

  access_by_lua_block {
    if ngx.var.name_upstream_1 ~= "" then
      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
    end
  }

It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

Configuring for use with the Traefik (v2) ForwardAuth middleware​

This option requires --reverse-proxy option to be set.

ForwardAuth with 401 errors middleware​

The Traefik v2 ForwardAuth middleware allows Traefik to authenticate requests via the oauth2-proxy's /oauth2/auth endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through.

    Endpoints

    OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

    • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
    • /ping - returns a 200 OK response, which is intended for use with health checks
    • /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by --metrics-address, disabled by default
    • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
    • /oauth2/sign_out - this URL is used to clear the session cookie
    • /oauth2/start - a URL that will redirect to start the OAuth cycle
    • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
    • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
    • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

    Sign out​

    To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

    /oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

    Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

    GET /oauth2/sign_out HTTP/1.1
    X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
    ...

    (The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

    BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored.

    Auth​

    This endpoint returns 202 Accepted response or a 401 Unauthorized response.

    It can be configured using the following query parameters query parameters:

    • allowed_groups: comma separated list of allowed groups
    • allowed_email_domains: comma separated list of allowed email domains
    • allowed_emails: comma separated list of allowed emails

    Behaviour

    1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
    2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
    3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
    4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

    Notice that the proxy also provides a number of useful endpoints.

    Upstream​

    (Appears on: UpstreamConfig)

    Upstream represents the configuration for an upstream server. Requests will be proxied to this upstream if the path matches the request path.

    FieldTypeDescription
    idstringID should be a unique identifier for the upstream.
    This value is required for all upstreams.
    pathstringPath is used to map requests to the upstream server.
    The closest match will take precedence and all Paths must be unique.
    Path can also take a pattern when used with RewriteTarget.
    Path segments can be captured and matched using regular experessions.
    Eg:
    - ^/foo$: Match only the explicit path /foo
    - ^/bar/$: Match any path prefixed with /bar/
    - ^/baz/(.*)$: Match any path prefixed with /baz and capture the remaining path for use with RewriteTarget
    rewriteTargetstringRewriteTarget allows users to rewrite the request path before it is sent to
    the upstream server.
    Use the Path to capture segments for reuse within the rewrite target.
    Eg: With a Path of ^/baz/(.*), a RewriteTarget of /foo/$1 would rewrite
    the request /baz/abc/123 to /foo/abc/123 before proxying to the
    upstream server.
    uristringThe URI of the upstream server. This may be an HTTP(S) server of a File
    based URL. It may include a path, in which case all requests will be served
    under that path.
    Eg:
    - http://localhost:8080
    - https://service.localhost
    - https://service.localhost/path
    - file://host/path
    If the URI's path is "/base" and the incoming request was for "/dir",
    the upstream request will be for "/base/dir".
    insecureSkipTLSVerifyboolInsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.
    This option is insecure and will allow potential Man-In-The-Middle attacks

    staticboolStatic will make all requests to this upstream have a static response.
    The response will have a body of "Authenticated" and a response code
    matching StaticCode.
    If StaticCode is not set, the response will return a 200 response.
    staticCodeintStaticCode determines the response code for the Static response.
    This option can only be used with Static enabled.
    flushIntervalDurationFlushInterval is the period between flushing the response buffer when

    Overview

    oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

    To generate a strong cookie secret use one of the below commands:

    python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

    Config File​

    Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

    An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

When combined with --reverse-proxy and optionally --real-client-ip-header this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

    [1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

    [2]: When using the whitelist-domain option, any domain prefixed with a . or a *. will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

    See below for provider specific options

    Upstreams Configuration​

    oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

    Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

    Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

    Environment variables​

    Every command line argument can be specified as an environment variable by +

    Version: 7.4.x

    Overview

    oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

    To generate a strong cookie secret use one of the below commands:

    python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

    Config File​

    Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

    An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

    Upstreams Configuration​

    oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

    Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

    Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

    Environment variables​

    Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

    This is particularly useful for storing secrets outside of a configuration file @@ -20,7 +20,7 @@ The default format is configured as follows:

    {{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}

    Available variables for request logging:

    If you require a different format than that, you can configure it with the --standard-logging-format flag. The default format is configured as follows:

    [{{.Timestamp}}] [{{.File}}] {{.Message}}

    Available variables for standard logging:

    VariableExampleDescription
    Timestamp19/Mar/2015:17:20:19 -0400The date and time of the logging event.

    Configuring for use with the Nginx auth_request directive​

    The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

    server {
      listen 443 ssl;
      server_name ...;
      include ssl/ssl.conf;

    When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

    nginx.ingress.kubernetes.io/auth-response-headers: Authorization
    nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
    nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
    nginx.ingress.kubernetes.io/configuration-snippet: |
      auth_request_set $name_upstream_1 $upstream_cookie_name_1;

      access_by_lua_block {
        if ngx.var.name_upstream_1 ~= "" then
          ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
        end
      }

    It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

    You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

    Configuring for use with the Traefik (v2) ForwardAuth middleware​

    This option requires --reverse-proxy option to be set.

    ForwardAuth with 401 errors middleware​

    The Traefik v2 ForwardAuth middleware allows Traefik to authenticate requests via the oauth2-proxy's /oauth2/auth endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through. For example, on Dynamic File (YAML) Configuration:

    http:

    Endpoints

    OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

    • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
    • /ping - returns a 200 OK response, which is intended for use with health checks
    • /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by --metrics-address, disabled by default
    • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
    • /oauth2/sign_out - this URL is used to clear the session cookie
    • /oauth2/start - a URL that will redirect to start the OAuth cycle
    • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
    • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
    • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive

    Sign out​

    To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

    /oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

    Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

    GET /oauth2/sign_out HTTP/1.1
    X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
    ...

    (The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

    BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored. Make sure to include the actual domain and port (if needed) and not the URL (e.g "localhost:8081" instead of "http://localhost:8081").

    Auth​

    This endpoint returns 202 Accepted response or a 401 Unauthorized response.

    It can be configured using the following query parameters query parameters:

    • allowed_groups: comma separated list of allowed groups
    • allowed_email_domains: comma separated list of allowed email domains

    Behaviour

    1. Any request passing through the proxy (and not matched by --skip-auth-regex) is checked for the proxy's session cookie (--cookie-name) (or, if allowed, a JWT token - see --skip-jwt-bearer-tokens).
    2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with Accept: application/json, in which case 401 Unauthorized is returned)
    3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
    4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)

    Notice that the proxy also provides a number of useful endpoints.

    Upstream represents the configuration for an upstream server. Requests will be proxied to this upstream if the path matches the request path.

    FieldTypeDescription
    idstringID should be a unique identifier for the upstream.
    This value is required for all upstreams.
    pathstringPath is used to map requests to the upstream server.
    The closest match will take precedence and all Paths must be unique.
    Path can also take a pattern when used with RewriteTarget.
    Path segments can be captured and matched using regular experessions.
    Eg:
    - ^/foo$: Match only the explicit path /foo
    - ^/bar/$: Match any path prefixed with /bar/
    - ^/baz/(.*)$: Match any path prefixed with /baz and capture the remaining path for use with RewriteTarget
    rewriteTargetstringRewriteTarget allows users to rewrite the request path before it is sent to
    the upstream server.
    Use the Path to capture segments for reuse within the rewrite target.
    Eg: With a Path of ^/baz/(.*), a RewriteTarget of /foo/$1 would rewrite
    the request /baz/abc/123 to /foo/abc/123 before proxying to the
    upstream server.
    uristringThe URI of the upstream server. This may be an HTTP(S) server of a File
    based URL. It may include a path, in which case all requests will be served
    under that path.
    Eg:
    - http://localhost:8080
    - https://service.localhost
    - https://service.localhost/path
    - file://host/path
    If the URI's path is "/base" and the incoming request was for "/dir",
    the upstream request will be for "/base/dir".

    Overview

    oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

    To generate a strong cookie secret use one of the below commands:

    python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

    Config File​

    Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

    An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

When combined with --reverse-proxy and optionally --real-client-ip-header this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

    [1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

    [2]: When using the whitelist-domain option, any domain prefixed with a . or a *. will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

    See below for provider specific options

    Upstreams Configuration​

    oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

    Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

    Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

    Environment variables​

    Every command line argument can be specified as an environment variable by +

    Version: Next

    Overview

    oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings).

    To generate a strong cookie secret use one of the below commands:

    python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(32)).decode())'

    Config File​

    Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the config option should be plural (trailing s).

    An example oauth2-proxy.cfg config file is in the contrib directory. It can be used by specifying --config=/etc/oauth2-proxy.cfg

WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them.

    [1]: Only these providers support --cookie-refresh: GitLab, Google and OIDC

    [2]: When using the whitelist-domain option, any domain prefixed with a . or a *. will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: example.com:8080. To allow any port, use *: example.com:*.

    See below for provider specific options

    Upstreams Configuration​

    oauth2-proxy supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as http://127.0.0.1:8080/ for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide http://127.0.0.1:8080/some/path/ then it will only be requests that start with /some/path/ which are forwarded to the upstream.

    Static file paths are configured as a file:// URL. file:///var/www/static/ will serve the files from that directory at http://[oauth2-proxy url]/var/www/static/, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. file:///var/www/static/#/static/ will make /var/www/static/ available at http://[oauth2-proxy url]/static/.

    Multiple upstreams can either be configured by supplying a comma separated list to the --upstream parameter, supplying the parameter multiple times or providing a list in the config file. When multiple upstreams are used routing to them will be based on the path they are set up with.

    Environment variables​

    Every command line argument can be specified as an environment variable by prefixing it with OAUTH2_PROXY_, capitalising it, and replacing hyphens (-) with underscores (_). If the argument can be specified multiple times, the environment variable should be plural (trailing S).

    This is particularly useful for storing secrets outside of a configuration file @@ -20,7 +20,7 @@ The default format is configured as follows:

    Configuring for use with the Nginx auth_request directive​

    The Nginx auth_request directive allows Nginx to authenticate requests via the oauth2-proxy's /auth endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:

    server {
      listen 443 ssl;
      server_name ...;
      include ssl/ssl.conf;

      location /oauth2/ {
        proxy_pass       http://127.0.0.1:4180;

        proxy_set_header X-Auth-Request-Redirect $request_uri;
        # or, if you are handling multiple domains:
        # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
      }
      location = /oauth2/auth {
        proxy_pass       http://127.0.0.1:4180;
        proxy_set_header Host             $host;
        proxy_set_header X-Real-IP        $remote_addr;
        proxy_set_header X-Scheme         $scheme;
        # nginx auth_request includes headers but not body
        proxy_set_header Content-Length   "";
        proxy_pass_request_body           off;
      }

      location / {
        auth_request /oauth2/auth;
        error_page 401 = /oauth2/sign_in;

        # pass information via X-User and X-Email headers to backend,
        # requires running with --set-xauthrequest flag

        auth_request_set $auth_cookie $upstream_http_set_cookie;
        add_header Set-Cookie $auth_cookie;

        # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
        # limit and so the OAuth2 Proxy splits these into multiple parts.
        # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
        # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
        auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;

        # Extract the Cookie attributes from the first Set-Cookie header and append them
        # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
        if ($auth_cookie ~* "(; .*)") {
            set $auth_cookie_name_0 $auth_cookie;
            set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
        }

        # Send both Set-Cookie headers now if there was a second part
        if ($auth_cookie_name_upstream_1) {
            add_header Set-Cookie $auth_cookie_name_0;
            add_header Set-Cookie $auth_cookie_name_1;
        }

        proxy_pass http://backend/;
        # or "root /path/to/site;" or "fastcgi_pass ..." etc
      }
    }

    When you use ingress-nginx in Kubernetes, you MUST use kubernetes/ingress-nginx (which includes the Lua module) and the following configuration snippet for your Ingress. Variables set with auth_request_set are not set-able in plain nginx config when the location is processed via proxy_pass and then may only be processed by Lua. Note that nginxinc/kubernetes-ingress does not include the Lua module.

    nginx.ingress.kubernetes.io/auth-response-headers: Authorization
    nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
    nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
    nginx.ingress.kubernetes.io/configuration-snippet: |
      auth_request_set $name_upstream_1 $upstream_cookie_name_1;

      access_by_lua_block {
        if ngx.var.name_upstream_1 ~= "" then
          ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
        end
      }

    It is recommended to use --session-store-type=redis when expecting large sessions/OIDC tokens (e.g. with MS Azure).

    You have to substitute name with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

    Configuring for use with the Traefik (v2) ForwardAuth middleware​

    This option requires --reverse-proxy option to be set.

    ForwardAuth with 401 errors middleware​

    The Traefik v2 ForwardAuth middleware allows Traefik to authenticate requests via the oauth2-proxy's /oauth2/auth endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through.

    Endpoints

    OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The /oauth2 prefix can be changed with the --proxy-prefix config variable.

    • /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see robotstxt.org for more info
    • /ping - returns a 200 OK response, which is intended for use with health checks
    • /ready - returns a 200 OK response if all the underlying connections (e.g., Redis store) are connected
    • /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by --metrics-address, disabled by default
    • /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
    • /oauth2/sign_out - this URL is used to clear the session cookie
    • /oauth2/start - a URL that will redirect to start the OAuth cycle
    • /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
    • /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
    • /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the Nginx auth_request directive
    • /oauth2/static/* - stylesheets and other dependencies used in the sign_in and error pages

    Sign out​

    To sign the user out, redirect them to /oauth2/sign_out. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the rd query parameter, i.e. redirect the user to something like (notice the url-encoding!):

    /oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page

    Alternatively, include the redirect URL in the X-Auth-Request-Redirect header:

    GET /oauth2/sign_out HTTP/1.1
    X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
    ...

    (The "sign_out_page" should be the end_session_endpoint from the metadata if your OIDC provider supports Session Management and Discovery.)

    BEWARE that the domain you want to redirect to (my-oidc-provider.example.com in the example) must be added to the --whitelist-domain configuration option otherwise the redirect will be ignored. Make sure to include the actual domain and port (if needed) and not the URL (e.g "localhost:8081" instead of "http://localhost:8081").

    Auth​

    This endpoint returns 202 Accepted response or a 401 Unauthorized response.

    It can be configured using the following query parameters query parameters:

    • allowed_groups: comma separated list of allowed groups
    • allowed_email_domains: comma separated list of allowed email domains
    • allowed_emails: comma separated list of allowed emails
