Server installation fails on K8s

Marahin commented 2 years ago

Describe the bug Hello! I am trying to deploy PZ using this image on Kubernetes (with storage being mounted through NFS), however the installation steps are failing.

To Reproduce Steps to reproduce the behavior:

Create all necessary Kubernetes manifests:

nfs:

server: storagemaster.local

Ensure NFS is available and path /mnt/ssd-pool/zomboid has two subdirectories: data and config, both set to chown 1017:1017 (zomboid:zomboid)
Apply the manifests

Expected behavior Container starting up, eventually running the server.

Actual behavior Container fails to run steamcmd.sh due to lack of permissions (the script is owned by steam:steam user, and when I run id steam within the container, it resolves to 1000:1000 - while the container runtime is already set to 1017:1017, which is zomboid:zomboid user).

In order to get past this issue, what I had to do is match uid and gid set in Dockerfile to the ones of my NFS user (1017). https://github.com/Marahin/zomboid-dedicated-server/commit/f322c954c4082c735b6b5a46c0c229b5971d0dd1

Is there any way to achieve that without having to resolve to build my custom image?

Hey, thanks for trying this out on K8S. I was meaning to give it a go, but never got around to it properly.

To be honest, I would say you are running into much the same issue that #19 and #24 are suffering from. I need to revise how I am handling folder permissions as there is definitely something going wrong between the SteamCMD base image, and the user actually deploying the Zomboid Container.

I am quite busy at the moment with other things, so I may not be able to address this particularly quickly. I would say that fixing the permissions issue will fix most of the problems people have been seeing.

If you have any ideas in the meantime, please feel free to make a PR on this or the SteamCMD repo that is reachable from my profile. 🙂

You should be able to override those if you set the build arguments for the Image.

And the worst you should have to do is to build the steamcmd-minimal image with your own IDs. Not ideal, I know. This is part of what I want to address.
