Does fluentd pod works with either /var/lib/docker or /var/lib/docker/containers without any modification? I would expect these 2 directories to contain different content.

[gnufied]

My main concern same as before is - this will again break in future if docker deployment causes "/var/lib/docker" to be mounted as private mount.

Rather than doing this here - is it possible to disable MountPropagation feature from inventory file that deploys the cluster to free-int? I tried making the same change in openshift-ansible - #7936 but now that I think of, since we are rolling back "slave" mount propagation defaults in upstream, modifying openshift-ansible may not be the right place.

[gnufied]

Any change we make in openshift-ansible will be temporary(and not required) to fix this issue once openshift/origin#19364 PR merges. So it is best to workaround this by disabling MountPropagation feature via inventory file.

[jsafrane]

openshift/origin#19364 was merged into Origin 3.10, so this PR is probably not needed. Sorry it took so long.

[ewolinetz]

Closing as the origin fix for this has merged
