Hi,
I am sometimes experiencing an issue where a new container can't write to
an existing volume after removing the old container. The containers are
running rootless on RHEL8.
I tried resetting the permissions on the volume by running the "podman
unshare" command again, but it seems to have no effect. If I create a new
volume and mount it to the new container, the new container can write to
the new volume.
Why is the new container unable to write to the existing volume, but able
to write to a new volume with supposedly identical permissions?
Sequence of events:
1. create volume and container
podman volume create <volume_name>
podman unshare chown 1000:1000 -R <path_to_volume>
podman run -d --name <container_name> ... --volume <volume_name>:/var/log:Z
... <container_image>
2. Some point in the future I get a new container image
podman container stop <container_name>
podman container rm <container_name>
podman run -d --name <container_name> ... --volume <volume_name>:/var/log:Z
... <new_container_image>
3. The new container logs show it is unable to write to the volume
Regards,
