CS running in docker - how to access files of a different container

[IonasElate]

Hello

i know the purpose of docker is having isolated services.
I cannot figure out how to access files of a different container (specifically i try to edit my openHAB files) wit code server.

i use the standard config of CS in docker:

code-server:
    image: lscr.io/linuxserver/code-server:latest
    container_name: code-server
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Berlin
      - PASSWORD=pw#optional
      #- HASHED_PASSWORD= #optional
      #- SUDO_PASSWORD=#optional
      #- SUDO_PASSWORD_HASH= #optional
      #- PROXY_DOMAIN=code-server.my.domain #optional
      #- DEFAULT_WORKSPACE=/config/workspace #optional
    volumes:
      - "./codeserver/config:/config"
    ports:
      - 8445:8443
    restart: always

can you push me in the right direction?

Thank you

out of my wheelhouse but maybe @code-asher or @bpmct can answer?

Your OpenHAB container is probably using a volume to persist those configuration files, right? The only thing that comes to my mind is to mount that same volume into the code-server container so it can read and edit those files. Ideally we would implement #1315 to support code-server editing into other Docker containers but that is not scheduled to be worked on at the moment. If you do not need browser support you could use native VS Code with the remote container plugin.

i was thinking about that too but was not sure if i should try it because i was scared of breaking something.

i will try tomorrow and report back. thanks a lot for your reply!

it worked like charm :-) just mounted the local folder to a directory inside the cs container.

[IonasElate]

Nope it doesnt :-)
i can view but not write (because the directory was created from another container). i will have to dig deeper in shared volumes.

[code-asher]

Ohhh right you will probably need to give permissions to the code-server user on the directory.

It worked, thank you! :-)
