could you please verify if these steps fix the issue for you? 1) create the directory "/var/lib/dockershim" on the host 2) adding this snippet to /var/lib/containers/atomic/atomic-openshift-node.0/config.json (under the mounts section): { "type": "bind", "source": "/var/lib/dockershim", "destination": "/var/lib/dockershim", "options": [ "bind", "slave", "rw", "mode=777" ] }, 3) systemctl restart atomic-openshift-node If you can confirm that, I'll prepare a patch to add the missing bind mount and ensure the directory exists on the host.
