Rustdesk in docker

guide-by-example

Purpose & Overview

Remote desktop application.

• Official site
• Github
• DockerHub

Rustdesk is a young opensource replacement for TeamViewer or Anydesk. The major thing is that it does NAT punching, and lets you host all the infrastructure for it to function.

Written in rust(gasp), with Dart and Flutter framework for client side.

Files and directory structure

/home/
└── ~/
    └── docker/
        └── rustdesk/
            ├── data/
            ├── .env
            └── docker-compose.yml

• data/ - relay server
• .env - a file containing environment variables for docker compose
• docker-compose.yml - a docker compose file, telling docker how to run the containers

You only need to provide the files.
The directories are created by docker compose on the first run.

docker-compose

Using edited version of S6-overlay based images.

docker-compose.yml

services:
  rustdesk:
    image: rustdesk/rustdesk-server-s6:latest
    container_name: rustdesk
    hostname: rustdesk
    restart: unless-stopped
    env_file: .env
    ports:
      - 21115:21115
      - 21116:21116
      - 21116:21116/udp
      - 21117:21117
      - 21118:21118
      - 21119:21119
    volumes:
      - ./data:/data

networks:
  default:
    name: $DOCKER_MY_NETWORK
    external: true

.env

# GENERAL
MY_DOMAIN=example.com
DOCKER_MY_NETWORK=caddy_net
TZ=Europe/Bratislava

# RUSTDESK
RELAY=rust.example.com:21117
ENCRYPTED_ONLY=1"

All containers must be on the same network.
Which is named in the .env file.
If one does not exist yet: docker network create caddy_net

Port forwarding

ports 21115 - 21119 needs to be open port 21116 open as tcp and udp

First run

Trouble shooting

If after update you cant see edit tools. Clear cookies.

Update

Manual image update:

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

Backup and restore

Backup

Using borg that makes daily snapshot of the entire directory.

Restore

• down the bookstack containers docker-compose down
  
• delete the entire bookstack directory
  
• from the backup copy back the bookstack directory
  
• start the containers docker-compose up -d

Backup of just user data

Users data daily export using the official procedure.
For bookstack it means database dump and backing up several directories containing user uploaded files.

Daily borg run takes care of backing up the directories. So only database dump is needed.
The created backup sqlite3 file is overwritten on every run of the script, but that's ok since borg is making daily snapshots.

Create a backup script

Placed inside bookstack directory on the host

bookstack-backup-script.sh

#!/bin/bash

# CREATE DATABASE DUMP, bash -c '...' IS USED OTHERWISE OUTPUT > WOULD TRY TO GO TO THE HOST
docker container exec bookstack-db bash -c 'mysqldump -u $MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE > $MYSQL_DIR/BACKUP.bookstack.database.sql'

the script must be executable - chmod +x bookstack-backup-script.sh

Cronjob

Running on the host, so that the script will be periodically run.

• su - switch to root
• crontab -e - add new cron job
  
• 0 22 * * * /home/bastard/docker/bookstack/bookstack-backup-script.sh
  runs it every day at 22:00
• crontab -l - list cronjobs to check

Restore the user data

Assuming clean start, first restore the database before running the app container.

• start only the database container: docker-compose up -d bookstack-db
• copy BACKUP.bookstack.database.sql in bookstack/bookstack-db-data/
• restore the database inside the container
  docker container exec --workdir /config bookstack-db bash -c 'mysql -u $MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE < BACKUP.bookstack.database.sql'
• now start the app container: docker-compose up -d
• let it run so it creates its file structure
• down the containers docker-compose down
• in bookstack/bookstack-data/www/
  replace directories files,images,uploads and the file .env
  with the ones from the BorgBackup repository
• start the containers: docker-compose up -d
• if there was a major version jump, exec in to the app container and run php artisan migrate
docker container exec -it bookstack /bin/bash
cd /var/www/html/
php artisan migrate

Again, the above steps are based on the official procedure.
