...working on it ;-)
Any special points of attention?

Nothing from my side - if it starts it should be as good as the old image.

Well, I can confirm x64 7.9.3 starts fine and is able to scan a local music library. I will test with several plugins enabled later.
I have used my docker-compose file as mentioned earlier in this thread, albeit on a different host (Win10pro instead of Xubuntu 20.04). LMS runs in its own (docker) network.

/edit:
I have done additional testing with Spotty, Material Skin and Music & Artists Info plugin. First impressions are ok.
Will do some testing with some library scan/rescan use cases later.

I mentioned it above - use host based networking. That's when you attach the container directly to the hosts network stack. You could in theory communicate with Docker from inside the container and have it map extra ports using the API, but that is even more hacky.

Let me provide you a docker-compose file that should just work. I've left your mounts as is, but you may want to use a volume

Code:

version: "2"
services:
 lms:
    image: doliana/logitech-media-server
    network_mode: host
    volumes:
      - /docker/squeezebox/state:/srv/squeezebox
      - /docker/squeezebox/music:/srv/music
      - /etc/localtime:/etc/localtime:ro

So far host based networking wasn't neccessary for my use cases with LMS & Docker. Do you have examples where it is really needed? Imho host based networking is never the first choice in te container world.

Can you post your compose.yml that's working on Windows 10? I'm trying to run under Windows 2019 w/Docker in a Linux container and it's just not working.

my compose:

Code:

version: '3'
services:
  squeezebox:
      container_name: squeezebox
      image: doliana/logitech-media-server:latest-SetProperVersions-7.9.3
      restart: unless-stopped
      environment:
        - TZ=America/New_York
      ports:
        - "9000:9000"
        - "9090:9090"
        - "3483:3483"
        - "3483:3483/udp" 
      volumes:
        - K:\Docker\configs\logitechmediaserver:/srv/squeezebox
        - M:\ServerFolders\music\:/srv/music
        - K:\Docker\timezone:/etc/timezone:ro

And the startup issue. Can't even get it going - seems to not init. And the files DO exist in the config volume, which is the baffling part.

I am using Docker via WSL2 & Windows, and also have Docker on several linux systems.
On Win10 my current docker-compose for LMS is:

Code:

  logitech-media-server:
    container_name: lms
#    image: doliana/logitech-media-server:latest-7.9.2
#    image: doliana/logitech-media-server:latest-8.0
    image: doliana/logitech-media-server:latest-SetProperVersions-7.9.3
    restart: unless-stopped
    ports:
      - "9000:9000"
      - "9090:9090"
      - "3483:3483"
      - "3483:3483/udp"
    volumes:
      # folder where lms stores its data (cache, logs, prefs)
      - ./lms_storage:/srv/squeezebox
      # folder where lms should look for music
      - /mnt/c/data/lms-music:/srv/music
    environment:
      # use time of host
      - /etc/localtime:/etc/localtime:ro
      # use timezone of host
      - TZ=${TZ}

The main difference is in the volumes/mappings, I am using mount points instead of drive letters. It seems to me that you have to look into that first.
My docker-compose file lives in a WSL2 Debian environment, therefore mappings must be defined from Linux perspective, not from Win10.

Yeah, that's what's baffling me. I have had ZERO problems with mapping for any other container I setup except for this one. Can't figure out why at all.

If I don't map the config folder, it works fine. So..it's something there. What it is though...I haven't a damn clue or even how to diagnose. Permissions are correct, date/time is correct - not even sure what else to look at.

EDIT: Doing some quick checks, it looks like the volume I map for config is owned by root when mapped and squeezeboxserver when not mapped. I've tried running the container as UID/GID:1000 (which is squeezeboxserver) and UID/GID:0 (root), and both result in the same issue.

EDIT2: I setup a Alpine Linux, installed docker, and tried mapping to the same underlying directories (mounted in Alpine of course)...and it works. So, basically this is some kind of permissioning issue with Docker on Windows w/a Linux container. If anyone has it working in that setup, let me know. While things are working fine w/the Linux container...I feel like it defeats the purpose.

I was responding to the request for "dynamic port publishing depending on installed plugins" by DOliana. I have no idea which plugins would need you to forward more ports into the container, but ¯\_(ツ)_/¯. I don't need it. I'm happy with a few mappings.

As a separate note, I mentioned earlier that LMS doesn't play nice with an overlay Swarm network, I think because it is NAT'd. But I get that most people deep in the container world don't play with that any more, and enjoy K8s instead.

So I don't use Windows, but I do see many people struggling with permissions. Why not use a volume? It's generally not recommended to persist data using a bind mount (but I know it is super common). Anyway, try something like this. You can add port mappings if you prefer.

Code:

version: "2"
services:
 lms:
    image: doliana/logitech-media-server
    network_mode: host
    volumes:
      - M:\ServerFolders\music:/srv/music
      - K:\Docker\timezone:/etc/timezone:ro
      - lms_config:/srv/squeezebox
volumes:
  lms_config:
