RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

docker-autotest reporting this failure on docker-1.10.3-55.el7.x86_64 et al:

    # docker run --rm --cgroup-parent=foo-bar.slice centos cat /proc/1/cgroup

What OS are you testing on? I do not see the pids cgroup enabled on my RHEL 7.2 VM.

RHEL 7.3, kernel 3.10.0-513.el7.x86_64

Thanks! I checked the code. We don't have the pids cgroups support for libcontainer in our docker 1.10.x branches. So, if we really want it in docker 1.10 then we need a backport which should be straight forward. 

Dan, wdyt about backporting to 1.10 or should we just support it in 1.12+?

I think we should just support this in docker-1.12 unless we are forced by OpenShift.  For now lets close this as fixed in docker-1.12.

In docker-1.12.3-4.el7.x86_64

# docker run --rm --cgroup-parent=foo-bar.slice rhel7 cat /proc/1/cgroup
.....
10:pids:/foo.slice/foo-bar.slice/docker-9788efa1b06cfa3dd86ad523c79dde6143740908b030d434fbeda03939b7365d.scope
