Won't chowning the socket also impact other things using said socket? IE portainer. If so, might want to think about setting a user field that someone can run the container as that will have access to said socket.

You are right, I didn't know that. I guess then we'll need to add PUID and PGID
Reference for me: https://docs.linuxserver.io/general/understanding-puid-and-pgid/#why-use-these

[Meierschlumpf]

What do you think of that solution? We allow the user to change PUID and PGID to whatever they need and chown the volumes the same way and internally still use the internal_user to run the processes as we don't want to change the owner of all files in the /app directory when starting up the container. But that user is member of the homarr group which is owner of the volumes
