Tips and tricks about Podman
Disable security in SELinux context
Most of the time just add :Z after volume parameters:
podman run -dit -v ./cockpit:/tmp/cockpit:z localhost/cockpit-builder
If it is not working, add --security-opt label=disable and the :z option to your volume
podman run -dit --security-opt label=disable -v ./cockpit:/tmp/cockpit:z localhost/cockpit-builder
