### docker-compose

  Dockerhub linuxserver/bookstack [example compose.](https://hub.docker.com/r/linuxserver/bookstack)

  `docker-compose.yml`

  ```
  version: "2"
  services:

    bookstack:
      image: linuxserver/bookstack
      container_name: bookstack
      hostname: bookstack
      environment:
        - PUID
        - PGID
        - DB_HOST
        - DB_USER
        - DB_PASS
        - DB_DATABASE
        - APP_URL
      volumes:
        - ./bookstack-data:/config
      restart: unless-stopped
      depends_on:
        - bookstack_db

    bookstack_db:
      image: linuxserver/mariadb
      container_name: bookstack_db
      hostname: bookstack_db
      environment:
        - PUID
        - PGID
        - MYSQL_ROOT_PASSWORD
        - TZ
        - MYSQL_DATABASE
        - MYSQL_USER
        - MYSQL_PASSWORD
      volumes:
        - ./bookstack-data-db:/config
      restart: unless-stopped

  networks:
    default:
      external:
        name: $DEFAULT_NETWORK
  ```

  `.env`

  ```
  # GENERAL
  MY_DOMAIN=blabla.org
  DEFAULT_NETWORK=caddy_net
  TZ=Europe/Prague

  # BOOKSTACK
  PUID=1000
  PGID=1000
  DB_HOST=bookstack_db
  DB_USER=bookstack
  DB_PASS=bookstack
  DB_DATABASE=bookstackapp
  APP_URL=https://book.blabla.org

  # BOOKSTACK-MARIADB
  PUID=1000
  PGID=1000
  MYSQL_ROOT_PASSWORD=bookstack
  MYSQL_DATABASE=bookstackapp
  MYSQL_USER=bookstack
  MYSQL_PASSWORD=bookstack
  ```

### Reverse proxy

  Caddy v2 is used,
  details [here](https://github.com/DoTheEvo/Caddy-v2-examples)

  `Caddyfile`
  ```
  {
      # acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
  }

  book.{$MY_DOMAIN} {
      reverse_proxy {
          to bookstack:80
      }
  }
  ```

### 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 backup of the entire directory
    
  * **restore**</br>
    down the bookstack containers `docker-compose down`</br>
    delete the entire bookstack directory</br>
    from the backup copy back the bookstack directortory</br>
    start the container `docker-compose up -d`

### Backup of just user data

For additional peace of mind,
user-data daily exported using the [official procedure.](https://www.bookstackapp.com/docs/admin/backup-restore/)</br>
For bookstack it means database dump and backing up several directories containing user uploaded files.
The created backup files are overwriten on every run of the script,
but borg backup is daily making snapshot of the entire directory.

* **create a backup script**</br>
    placed inside `bookstack` directory on the host

    `bookstack-backup-script.sh`
    ```
    #!/bin/sh

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

    # ARCHIVE UPLOADED FILES
    docker container exec bookstack tar -czPf /config/BACKUP.bookstack.uploaded-files.tar.gz /config/www/
    ```

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

* **cronjob** on the host</br>
  `crontab -e` - add new cron job</br>
  `0 2 * * * /home/bastard/docker/bookstack/bookstack-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, first restore the database before running the app container.

  * start only the database container: `docker-compose up -d bookstack_db`
  * have `BACKUP.bookstack.database.sql` mounted in
  * exec in to the container and restore the database</br>
    `docker container exec -it bookstack_db /bin/bash`</br>
    `cd /config`</br>
    `mysql -u $MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE < BACKUP.bookstack.database.sql`
  * now start both containers: `docker-compose up -d`
  * let it run so it creates folder structure
  * down the containers `docker-compose down`
  * extract `BACKUP.bookstack.uploaded-files.tar.gz` and place directories `files` and `uploads` where they belong in the mounted volume
  * start the containers: `docker-compose up -d`
  * if there was a major version jump, exec in to the container and run `php artisan migrate`</br>
    `docker container exec -it bookstack /bin/bash`</br>
    `cd /var/www/html/`</br>
    `php artisan migrate`
