services:

  bitwarden:
    image: bitwardenrs/server
    container_name: bitwarden
    hostname: bitwarden
    restart: unless-stopped
    env_file: .env
    volumes:

All containers must be on the same network.
If one does not exist yet: docker network create caddy_net

Reverse proxy

Caddy v2 is used, details here.
Bitwarden_rs documentation has a section on reverse proxy.

Caddyfile

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 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.
  
• Reverse proxy needs to route /notifications/hub to port 3012.
  
• 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 updates the image automaticly

• manual image update
  docker-compose pull
docker-compose up -d
docker image prune

Backup and restore

• backup using BorgBackup setup that makes daily snapshot of the entire directory

• restore
  down the bitwarden container docker-compose down
  delete the entire bitwarden directory
  from the backup copy back the bitwarden directortory
  start the container docker-compose up -d

Backup of just user data

User-data daily export using the official procedure.
For bitwarden_rs it means sqlite database dump and backing up attachments directory.

Daily run of BorgBackup 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 BorgBackup is making daily snapshots.

• create a backup script
  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
  crontab -e - add new cron job
  0 2 * * * /home/bastard/docker/bitwarden/bitwarden-backup-script.sh - run it at 02:00
  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/
  replace db.sqlite3 with the backup one BACKUP.bitwarden.db.sqlite3
  replace attachments directory with the one from the BorgBackup repository
• start the container docker-compose up -d
