That would cause all the pods are pending with "ContainerCreating" state due to "Failed create pod sandbox".

Check /etc/systemd/system/atomic-openshift-node.service, found no "-v /var/lib/origin/.docker:/root/.docker:ro" is added there.

Check openshift-ansible code, the root cause is "Create credentials for registry auth (alternative)" task is skipped, "node_oreg_auth_credentials_create" is overwritten, that lead to the when judgment for "Setup ro mount of /root/.docker for containerized hosts" task is set to FALSE, so the task is skipped.


This bug is should be a regression bug introduced by "0de92e0e4c85c876436ae21f61daee31c870705e"
