Run nodebb inside of docker container



  • Hi,
    I tried to run nodebb/docker with a redis db as swarm / stack.

    compose:

    version: '3.7'
    services:
    
      nodebb:
        image: nodebb/docker
        networks:
          webproxy:
          redis:
        labels:
          # caddy swarm reverse proxy with lets encrypt
          caddy.address: "nodebb.example.com"
          caddy.targetport: '4567'
          caddy.log: '/ stdout "[{host}] {remote} - {user} [{when}] \"{method} {uri} {proto}\" {status} {size}"'
          caddy.errors: "stdout"  
        stdin_open: true
        tty: true         
        volumes:
          - build:/usr/src/app/build
          - uploads:/usr/src/app/public/uploads
        deploy:            
          restart_policy:  
            condition: any 
            delay: 10s     
            max_attempts: 5
            window: 60s
    
      redis:
        image: redis:5.0.7
        networks:
          redis:
        volumes:
          - data:/data
        command: 'redis-server --appendonly yes'  
        
    
    networks:
      webproxy:
        external:
          name: proxy_webproxy
      redis:
    
    volumes:
      data:
      build:
      uploads:
    

    After setup is finished I click the "Launch" button and that kills the container:

    2019-12-28T11:54:49.017Z [19] - info: [build] Asset compilation successful. Completed in 140.239sec.
    
         
    
    NodeBB Setup Completed. Run "./nodebb start" to manually start your NodeBB server.
    
    Starting NodeBB
        "./nodebb stop" to stop the NodeBB server
        "./nodebb log" to view server output
        "./nodebb restart" to restart NodeBB
    

    Would be no problem because of swarm restart_policy a new container should start...
    But after that I get the installer again instead of the installed nodebb forum.

    So something seems to be wrong. Redis DB is empty and nodebb volumes contains data.
    See below:

    rancher:/var/lib/docker/volumes# ls -lh nodebb_*/_data/
    nodebb_build/_data/:
    total 12
    -rw-r--r--    1 root     root          11 Dec 28 11:54 cache-buster
    drwxr-xr-x    2 root     root        4.0K Dec 28 11:33 export
    drwxr-xr-x    7 root     root        4.0K Dec 28 11:53 public
    
    nodebb_data/_data/:
    total 132
    -rw-r--r--    1 999      ping      129.8K Dec 28 11:52 appendonly.aof
    
    nodebb_uploads/_data/:
    total 20
    drwxr-xr-x    2 root     root        4.0K Dec 28 11:25 category
    drwxr-xr-x    2 root     root        4.0K Dec 28 11:25 files
    drwxr-xr-x    2 root     root        4.0K Dec 28 11:25 profile
    drwxr-xr-x    2 root     root        4.0K Dec 28 11:25 sounds
    

    So how to install with persistent data?

    Why no redis data is written to the volume?
    I'm new with redis, but it should work without password because I haven't set an password?
    Redis connect works fine from nodebb to redis container:

    root@a8dd26787f8f:/usr/src/app# telnet redis 6379
    Trying 10.0.19.2...
    Connected to redis.
    Escape character is '^]'.
    quit
    +OK
    Connection closed by foreign host.
    


  • If I restart the running nodebb container it would work, but docker swarm respawn a new container to the first one after I manually restart it...

    Also tested to add the install directory as volume if there would be changes after web install is finished, but same problem.
    Each time a new container is spawned I get the web installer again...

    It would help to now WHY I get the installer each time and how to solve that with the nodebb/docker image (with additional persistent volumes)?



  • @Staff
    After some more debugging I found the config.json file inside of the "/usr/src/app" directory, which prevents the image to update the nodebb app by pulling a new image...

    Any change to get the config.json moved to a sub directory "config"? Or wouldn't work nodebb inside of a docker container that way?
