See the README for usage with Dex or any other OIDC provider.
To test run a backend:
python3 -m http.server
Run dex and modify the example config with the proxy callback:
go get github.com/coreos/dex/cmd/dex
cd $GOPATH/src/github.com/coreos/dex
sed -i.bak \
's|http://127.0.0.1:5555/callback|http://127.0.0.1:5555/oauth2/callback|g' \
examples/config-dev.yaml
make
./bin/dex serve examples/config-dev.yaml
Then run the oauth2_proxy
oauth2_proxy \
--oidc-issuer-url http://127.0.0.1:5556/dex \
--upstream http://localhost:8000 \
--client-id example-app \
--client-secret ZXhhbXBsZS1hcHAtc2VjcmV0 \
--cookie-secret foo \
--email-domain '*' \
--http-address http://127.0.0.1:5555 \
--redirect-url http://127.0.0.1:5555/oauth2/callback \
--cookie-secure=false
Login with the username/password "admin@example.com:password"
golang.org/x/oauth2/google is same repo as golang.org/x/oauth2
- this sometimes confused gpm/git
cloud.google.com/go/compute/metadata is a missing dependency
of golang.org/x/oauth2
This change extracts the UserMap class from NewValidator() so that its
LoadAuthenticatedEmailsFile() method can be called concurrently. This method
is called by a goroutine containing a fsnotify.Watcher watching the
authenticated emails file.
Watching isn't forever aborted when the authenticated emails file disappears.
The goroutine will call os.Stat() up to twenty times a second if the file is
persistently missing, but that's the pathological case, not the common one.
The common case is that some editors (including Vim) will perform a
rename-and-replace when updating a file, triggering fsnotify.Rename events,
and the file will temporarily disappear. This watcher goroutine handles that
case.
Also, on some platforms (notably Arch Linux), a remove will be preceded by a
fsnotify.Chmod, causing a race between the upcoming fsnotify.Remove and the
call to UserMap.LoadAuthenticatedEmailsFile(). Hence, we treat fsnotify.Chmod
the same as fsnotify.Remove and fsnotify.Rename. There's no significant
penalty to re-adding a file to the watcher.
