NetAlertX/docs/MIGRATION.md

Migration form PiAlert to NetAlertX

Warning

Follow this guide only after you you downloaded and started NetAlert X at least once after previously using the PiAlert image.

Tip

In short: The application will auto-migrate the database, config, and all device information. A ticker message on top will be displayed until you update your docker mount points. Even so, it's always good to have a backup strategy in place.

The migration should be pretty straightforward. The application installation folder in the docker container has changed from /home/pi/pialert to /app. That means the new mount points are:

Old mount point	New mount point
/home/pi/pialert/config	/app/config
/home/pi/pialert/db	/app/db

If you were mounting files directly, please note the file names have changed:

Old file name	New file name
pialert.conf	app.conf
pialert.db	app.db

Note

The application uses symlinks linking the old db and config locations to the new ones, so data loss should not occur. Backup strategies are still recommended to backup your setup.

In summary:

1. Docker file mount locations in your docker-compose.yml or docker run command have changed.
2. Backup your current config and database (optional devices.csv to have a backup)
3. Rename them to app.db app.conf
4. Update the volume mappings in your docker-compose.yaml
5. Place the renamed files the above locations.

Tip

If you have troubles accessing past backups, config or database files you can copy them into the newly mapped directories, for example by running this command in the container: cp -r /app/config /home/pi/pialert/config/old_backup_files. This should create a folder in the config directory called old_backup_files conatining all the files in that location. Another approach is to map the old location and the new one at the same time to copy things over.

Examples follow.

Example 1: Mapping folders

Old docker-compose.yml

version: "3"
services:
  pialert:
    container_name: pialert
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest" 
    image: "jokobsk/pialert:latest"      
    network_mode: "host"        
    restart: unless-stopped
    volumes:
      - local/path/config:/home/pi/pialert/config  
      - local/path/db:/home/pi/pialert/db         
      # (optional) useful for debugging if you have issues setting up the container
      - local/path/logs:/home/pi/pialert/front/log
    environment:
      - TZ=Europe/Berlin      
      - PORT=20211

New docker-compose.yml

version: "3"
services:
  netalertx:                                  # ⚠  This has changed (🟡optional) 
    container_name: netalertx                 # ⚠  This has changed (🟡optional) 
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest" 
    image: "jokobsk/netalertx:latest"         # ⚠  This has changed (🟡optional/🔺required in future) 
    network_mode: "host"        
    restart: unless-stopped
    volumes:
      - local/path/config:/app/config         # ⚠  This has changed (🔺required) 
      - local/path/db:/app/db                 # ⚠  This has changed (🔺required) 
      # (optional) useful for debugging if you have issues setting up the container
      - local/path/logs:/app/front/log        # ⚠  This has changed (🟡optional) 
    environment:
      - TZ=Europe/Berlin      
      - PORT=20211

Example 2: Mapping files

Note

The recommendation is to map folders as in Example 1, map files directly only when needed.

Old docker-compose.yml

version: "3"
services:
  pialert:
    container_name: pialert
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest" 
    image: "jokobsk/pialert:latest"      
    network_mode: "host"        
    restart: unless-stopped
    volumes:
      - local/path/config/pialert.conf:/home/pi/pialert/config/pialert.conf  
      - local/path/db/pialert.db:/home/pi/pialert/db/pialert.db         
      # (optional) useful for debugging if you have issues setting up the container
      - local/path/logs:/home/pi/pialert/front/log
    environment:
      - TZ=Europe/Berlin      
      - PORT=20211

New docker-compose.yml

version: "3"
services:
  netalertx:                                  # ⚠  This has changed (🟡optional) 
    container_name: netalertx                 # ⚠  This has changed (🟡optional) 
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest" 
    image: "jokobsk/netalertx:latest"         # ⚠  This has changed (🟡optional/🔺required in future) 
    network_mode: "host"        
    restart: unless-stopped
    volumes:
      - local/path/config/app.conf:/app/config/app.conf # ⚠  This has changed (🔺required) 
      - local/path/db/app.db:/app/db/app.db             # ⚠  This has changed (🔺required) 
      # (optional) useful for debugging if you have issues setting up the container
      - local/path/logs:/app/front/log                  # ⚠  This has changed (🟡optional) 
    environment:
      - TZ=Europe/Berlin      
      - PORT=20211
