SELinuxඞ

When attempting to mount a host volume into a Podman container on a system where SELinux is enabled, the container may fail to start, or access to the volume may be denied due to SELinux policy restrictions.

Use :z or :Z volume mount options (mount argument as /data/appdata:/appdata:Z), these flags relabel the host directory for container access:

:z – Use when the volume is shared between multiple containers. :Z – Use when the volume is private to a single container.
