UID=1000 required inside php container on rootless docker?

[Trogie]

Hello, I am running my docker rootless (i.e dockerd is not root anymore, but one of the users on the system (https://docs.docker.com/engine/security/rootless/).

I wonder if the app user (uid 1000) inside the php docker container is still necessary then? This because it's gives me problems with the volume mapping on the host system (especially the different uid:gid's between rootless docker and the host)
