Cache volume is not writable in rootless build container

[MShekow]

I'm on RHEL 8.6 and I'm running a rootless build via podman build -f Dockerfile . with a very simple Dockerfile:

FROM busybox:latest
RUN --mount=type=cache,id=some-cache,target=/cache touch /cache/foo

The RUN statement fails with touch: /cache/foo: Permission denied

Is this expected behavior? What do I need to do to get it working?

Hi @MShekow , Is SElinux enabled ? if yes consider adding a RUN --mount=type=cache,id=some-cache,target=/cache,z touch /cache/foo

That worked, thank you!
