🔖 Feature description

Hi!
I just tried installing dockge on my host and I noticed the default docker socket is /var/run/docker.sock (as it should be on a default root Docker installation).

I installed Docker as rootless so my socket location is different, something like /run/user/1000/docker.sock so I had to modify the pregenerated compose.yaml file. (Nothing too difficult but I think it would be cool to have this automatically checked)

✔️ Solution

I think it may be useful to add the option here to use a custom Docker socket or a simple checkbox to use the default rootless Docker socket (alternatively reading DOCKER_HOST environment variable).

❓ Alternatives

dockge apparently uses the docker cli under the hood, so it respects the DOCKER_HOST environment variable. I modified my dockge compose.yaml to include a socket-proxy service and set DOCKER_HOST appropriately and it works fine. Here is a gist of a compose.yaml with dockge and socket-proxy.

I understand the socket proxy thing but wouldn't it be easier to just change the bind mount for the Dockge container?
Thanks

Sorry to revive an older thread, did you guys have any success with this while trying to authenticate with private container registries? I keep getting 403 unauthorized from gitlab when I mount /home/<rootless_docker_user>/.docker/config.json into the container.

Hi, does anyone have a simpler method just changing bind mount? I was looking here to see examples but couldn't seem to get it to work: https://stackoverflow.com/questions/68331153/docker-rootless-error-you-need-to-share-your-docker-host-socket-with-a-volume-a

On my setup I'm using:

volumes:
      - /run/user/1000/docker.sock:/var/run/docker.sock

and it works

Thanks so much, that worked perfectly!
