## Configure
## 1. Prepare CouchDB
### A. Using Docker container
The easiest way to set up a CouchDB instance is using the official [docker image](https://hub.docker.com/_/couchdb).
#### 1. Prepare
```bash
Some initial configuration is required. Create a `local.ini` to use Self-hosted LiveSync as follows ([CouchDB has to be version 3.2 or higher](https://docs.couchdb.org/en/latest/config/http.html#chttpd/enable_cors), if lower `enable_cors = true` has to be under section `[httpd]` ):
# Prepare environment variables.
export hostname=localhost:5984
export username=goojdasjdas #Please change as you like.
export password=kpkdasdosakpdsa #Please change as you like
```ini
[couchdb]
single_node=true
max_document_size = 50000000
[chttpd]
require_valid_user = true
max_http_request_size = 4294967296
enable_cors = true
[chttpd_auth]
require_valid_user = true
authentication_redirect = /_utils/session.html
[httpd]
WWW-Authenticate = Basic realm="couchdb"
bind_address = 0.0.0.0
[cors]
origins = app://obsidian.md, capacitor://localhost, http://localhost
credentials = true
headers = accept, authorization, content-type, origin, referer
methods = GET,PUT,POST,HEAD,DELETE
max_age = 3600
# Prepare directories which saving data and configurations.
mkdir couchdb-data
mkdir couchdb-etc
```
## Run
#### 2. Run docker container
### Docker CLI
1. Boot Check.
```
$ docker run --name couchdb-for-ols --rm -it -e COUCHDB_USER=${username} -e COUCHDB_PASSWORD=${password} -v ${PWD}/couchdb-data:/opt/couchdb/data -v ${PWD}/couchdb-etc:/opt/couchdb/etc/local.d -p 5984:5984 couchdb
```
If your container has been exited, please check the permission of couchdb-data, and couchdb-etc.
Once CouchDB run, these directories will be owned by uid:`5984`. Please chown it for you again.
You can launch CouchDB using your `local.ini` like this:
2. Enable it in background
```
$ docker run --rm -it -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v /path/to/local.ini:/opt/couchdb/etc/local.ini -p 5984:5984 couchdb
$ docker run --name couchdb-for-ols -d --restart always -e COUCHDB_USER=${username} -e COUCHDB_PASSWORD=${password} -v ${PWD}/couchdb-data:/opt/couchdb/data -v ${PWD}/couchdb-etc:/opt/couchdb/etc/local.d -p 5984:5984 couchdb
```
*Remember to replace the path with the path to your local.ini*
### B. Install CouchDB directly
Please refer the [official document](https://docs.couchdb.org/en/stable/install/index.html). However, we do not have to configure it fully. Just administrator needs to be configured.
Run in detached mode:
## 2. Run couchdb-init.sh for initialise
```
$ docker run -d --restart always -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v /path/to/local.ini:/opt/couchdb/etc/local.ini -p 5984:5984 couchdb
```
*Remember to replace the path with the path to your local.ini*
### Docker Compose
Create a directory, place your `local.ini` within it, and create a `docker-compose.yml` alongside it. Make sure to have write permissions for `local.ini` and the about to be created `data` folder after the container start. The directory structure should look similar to this:
```
obsidian-livesync
├── docker-compose.yml
└── local.ini
$ curl -s https://raw.githubusercontent.com/vrtmrz/obsidian-livesync/main/utils/couchdb/couchdb-init.sh | bash
```
A good place to start for `docker-compose.yml`:
```yaml
version: "2.1"
services:
couchdb:
image: couchdb
container_name: obsidian-livesync
user: 1000:1000
environment:
- COUCHDB_USER=admin
- COUCHDB_PASSWORD=password
volumes:
- ./data:/opt/couchdb/data
- ./local.ini:/opt/couchdb/etc/local.ini
ports:
- 5984:5984
restart: unless-stopped
If it results like following:
```
-- Configuring CouchDB by REST APIs... -->
{"ok":true}
""
""
""
""
""
""
""
""
""
<-- Configuring CouchDB by REST APIs Done!
```
And finally launch the container
Your CouchDB has been initialised successfully. If you want this manually, please read the script.
## 3. Expose CouchDB to the Internet
- You can skip this instruction if you using only in intranet and only with desktop devices.
- For mobile devices, Obsidian requires a valid SSL certificate. Usually, it needs exposing the internet.
Whatever solutions we can use. For the simplicity, following sample uses Cloudflare Zero Trust for testing.
```
# -d will launch detached so the container runs in background
docker compose up -d
$ cloudflared tunnel --url http://localhost:5984
2024-02-14T10:35:25Z INF Thank you for trying Cloudflare Tunnel. Doing so, without a Cloudflare account, is a quick way to experiment and try it out. However, be aware that these account-less Tunnels have no uptime guarantee. If you intend to use Tunnels in production you should use a pre-created named tunnel by following: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps
2024-02-14T10:35:25Z INF Requesting new quick Tunnel on trycloudflare.com...
2024-02-14T10:35:26Z INF +--------------------------------------------------------------------------------------------+
2024-02-14T10:35:26Z INF | Your quick Tunnel has been created! Visit it at (it may take some time to be reachable): |
2024-02-14T10:35:26Z INF | https://tiles-photograph-routine-groundwater.trycloudflare.com |
2024-02-14T10:35:26Z INF +--------------------------------------------------------------------------------------------+
:

:
```
Now `https://tiles-photograph-routine-groundwater.trycloudflare.com` is our server. Make it into background once please.
## 4. Client Setup
> [!TIP]
> Now manually configuration is not recommended for some reasons. However, if you want to do so, please use `Setup wizard`. The recommended extra configurations will be also set.
### 1. Generate the setup URI on a desktop device or server
```bash
$ export hostname=https://tiles-photograph-routine-groundwater.trycloudflare.com #Point to your vault
$ export database=obsidiannotes #Please change as you like
$ export passphrase=dfsapkdjaskdjasdas #Please change as you like
$ deno run -A https://raw.githubusercontent.com/vrtmrz/obsidian-livesync/main/utils/flyio/generate_setupuri.ts
obsidian://setuplivesync?settings=%5B%22tm2DpsOE74nJAryprZO2M93wF%2Fvg.......4b26ed33230729%22%5D
```
## Access from a mobile device
If you want to access Self-hosted LiveSync from mobile devices, you need a valid SSL certificate.
### 2. Setup Self-hosted LiveSync to Obsidian
[This video](https://youtu.be/7sa_I1832Xc?t=146) may help us.
1. Install Self-hosted LiveSync
2. Choose `Open the Setup URI` from the command palette and paste the setup URI. (obsidian://setuplivesync?settings=.....).
3. Type `welcome` for setup-uri passphrase.
4. Answer `yes` and `Set it up...`, and finish the first dialogue with `Keep them disabled`.
5. `Reload app without save` once.
### Testing from a mobile
In the testing phase, [localhost.run](https://localhost.run/) or something like services is very useful.
---
example using localhost.run:
```
$ ssh -R 80:localhost:5984 nokey@localhost.run
Warning: Permanently added the RSA host key for IP address '35.171.254.69' to the list of known hosts.
===============================================================================
Welcome to localhost.run!
Follow your favourite reverse tunnel at [https://twitter.com/localhost_run].
**You need a SSH key to access this service.**
If you get a permission denied follow Gitlab's most excellent howto:
https://docs.gitlab.com/ee/ssh/
*Only rsa and ed25519 keys are supported*
To set up and manage custom domains go to https://admin.localhost.run/
More details on custom domains (and how to enable subdomains of your custom
domain) at https://localhost.run/docs/custom-domains
To explore using localhost.run visit the documentation site:
https://localhost.run/docs/
===============================================================================
** your connection id is xxxxxxxxxxxxxxxxxxxxxxxxxxxx, please mention it if you send me a message about an issue. **
xxxxxxxx.localhost.run tunneled with tls termination, https://xxxxxxxx.localhost.run
Connection to localhost.run closed by remote host.
Connection to localhost.run closed.
```
https://xxxxxxxx.localhost.run is the temporary server address.
