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.

Description Qian Cai 2016-04-18 21:02:20 UTC
Description of problem:
Right now, everything goes to /run/docker/. The easy part to fix this is to pass --exec-root /run/docker-latest to the docker-latest unit file. The hard part is that netns seems hard-cored and does not honor --exec-root.

# mount
...
proc on /run/docker/netns/8d54a73b0709 type proc (rw,nosuid,nodev,noexec,relatime)

This might be one of reasons caused bug 1328204 . Once this is fixed, we can test to see if that will solve the mentioned bug.

Version-Release number of selected component (if applicable):
docker-latest-1.10.3-9.el7.x86_64

How reproducible:
always

Comment 2 Daniel Walsh 2016-05-03 15:15:12 UTC
We don't want to support two versions of docker at the same time, since /run/docker.sock is built into two many tools, I don't think we should do this.

Comment 3 Qian Cai 2016-05-03 17:32:16 UTC
As far as I can tell, docker.sock is always hard-coded in /run/docker/ and does NOT honor --exec-root .
