Additional context

This can have multiple use cases, I need this to place some custom certificates (read from secrets) under /data/server/tls before the server's initial start.

Hey @MohamedZ3kri ! You should be able to mount these via regular ConfigMaps / Secrets, which is usually a better approach than using init containers. In general we could think about such an option though.

Unfortunately regular ConfigMaps / Secrets won't work, I'm trying to mount the certificates based on the solution described here, If I mount the configmap directly under /data/server/tls I get a read-only file system error.

level=fatal msg="starting kubernetes: preparing server: open /data/server/tls/client-ca.nochain.crt: read-only file system"

@MohamedZ3kri do you mount the complete folder? I guess you need to mount the individual files only as k3s is trying to write other things into the folder

yes mounting the 6 files separately solved the read-only file system error, thank you.
