# Purpose

Password manager. RS version is simpler and lighter than the official bitwarden.

* [Official site](https://bitwarden.com/)
* [Github](https://github.com/dani-garcia/bitwarden_rs)
* [DockerHub](https://hub.docker.com/r/bitwardenrs/server)

  [Documentation](https://github.com/dani-garcia/bitwarden_rs/wiki/Using-Docker-Compose) on compose.

  `docker-compose.yml`

  **All containers must be on the same network**.</br>
  If one does not exist yet: `docker network create caddy_net`

# Reverse proxy

  Caddy v2 is used, details [here.](https://github.com/DoTheEvo/Caddy-v2-docker-example-setup)</br>
  Bitwarden_rs documentation has a [section on reverse proxy.](https://github.com/dani-garcia/bitwarden_rs/wiki/Proxy-examples)
  
  `Caddyfile`
  ```
  {
      # acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
  }

  passwd.{$MY_DOMAIN} {
      header / {
         X-XSS-Protection "1; mode=block"
         X-Frame-Options "DENY"
         X-Robots-Tag "none"
         -Server
      }
      encode gzip
      reverse_proxy /notifications/hub/negotiate bitwarden:80
      reverse_proxy /notifications/hub bitwarden:3012
      reverse_proxy bitwarden:80
  }
  ```

# Forward port 3012 TCP on your router

[WebSocket](https://youtu.be/2Nt-ZrNP22A) protocol is used for notifications,
so that all web based clients can immediatly sync when a change happens on server.

* Enviromental variable `WEBSOCKET_ENABLED=true` needs to be set.</br>
* Reverse proxy needs to route `/notifications/hub` to port 3012.</br>
* Router needs to **forward port 3012** to docker host,
same as port 80 and 443 are forwarded.

To test if websocket works, have the desktop app open
and make changes through browser extension, or through the website.
Changes should immediatly appear in the desktop app. If it is not working,
you need to manually sync for changes to appear.
 
# Extra info

**bitwarden can be managed** at `<url>/admin` and entering `ADMIN_TOKEN`
set in the `.env` file. Especially if signups are disabled it is the only way
to invite users.

**push notifications**

# Update

  * [watchtower](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/watchtower) updates the image automaticly

  * manual image update</br>
    `docker-compose pull`</br>
    `docker-compose up -d`</br>
    `docker image prune`

# Backup and restore

  * **backup** using [borgbackup setup](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/borg_backup)
  that makes daily snapshot of the entire directory
    
  * **restore**</br>
    down the bitwarden container `docker-compose down`</br>
    delete the entire bitwarden directory</br>
    from the backup copy back the bitwarden directortory</br>
    start the container `docker-compose up -d`

# Backup of just user data

User-data daily export using the [official procedure.](https://github.com/dani-garcia/bitwarden_rs/wiki/Backing-up-your-vault)</br>
For bitwarden_rs it means sqlite database dump and backing up `attachments` directory.</br>

Daily run of [borg backup](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/borg_backup)
takes care of backing up the directory.
So only database dump is needed.
The created backup sqlite3 file is overwriten on every run of the script,
but that's ok since borg backup is making daily snapshots.

* **create a backup script**</br>
    placed inside `bitwarden` directory on the host
    
    `bitwarden-backup-script.sh`
    ```
    #!/bin/bash

    # CREATE SQLITE BACKUP
    docker container exec bitwarden sqlite3 /data/db.sqlite3 ".backup '/data/BACKUP.bitwarden.db.sqlite3'"
    ```

    the script must be **executabe** - `chmod +x bitwarden-backup-script.sh`

* **cronjob** on the host</br>
  `crontab -e` - add new cron job</br>
  `0 2 * * * /home/bastard/docker/bitwarden/bitwarden-backup-script.sh` - run it [at 02:00](https://crontab.guru/#0_2_*_*_*)</br>
  `crontab -l` - list cronjobs

# Restore the user data

  Assuming clean start.

  * start the bitwarden container: `docker-compose up -d`
  * let it run so it creates its file structure
  * down the container `docker-compose down`
  * in `bitwarden/bitwarden-data/`</br>
    replace `db.sqlite3` with the backup one `BACKUP.bitwarden.db.sqlite3`</br>
    replace `attachments` directory with the one from the borg backup repository 
  * start the container `docker-compose up -d`
