[Podman] Re: volume permission issues after deleting / recreating 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, -- Jeremy V. _______________________________________________ Podman mailing list -- podman(a)lists.podman.io To unsubscribe send an email to podman-leave(a)lists.podman.io The second :Z relabels the content of the volume to be private to the second container. This means the first container can not longer read/write it. Use :z if you want to share a volume between multiple containers. Note the :z only needs to be done ONCE. Once it is done, all containers can use it as a volume. _______________________________________________ Podman mailing list -- podman(a)lists.podman.io To unsubscribe send an email to podman-leave(a)lists.podman.io
