Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Ed Santiago 2017-05-11 17:35:22 UTC
# yum update docker
    ...
    Running transaction
      Updating   : 2:docker-common-1.12.6-25.git62520c0.el7.x86_64                                                           1/8

    Cannot connect to the Docker daemon. Is the docker daemon running on this host?
    "docker stop" requires at least 1 argument(s).
    See 'docker stop --help'.

    Usage:  docker stop [OPTIONS] CONTAINER [CONTAINER...]

    Stop one or more running containers
      Updating   : 2:docker-1.12.6-25.git62520c0.el7.x86_64
    ....

Root cause: specfile line 518:

    %{_bindir}/%{name} stop $(%{_bindir}/%{name} ps -a -q)

Proposed solution: check if daemon is running:

    systemctl --quiet is-active %{name} && ....etc

Comment 4 Luwen Su 2017-05-15 09:47:33 UTC
I don't see the warning during update from docker-1.12.6-20 to docker-1.12.6-26.git62520c0.el7.x86_64, move to verified.

Comment 6 Ed Santiago 2017-05-25 20:03:22 UTC
Moving back to ASSIGNED: although the "Cannot connect to the Docker daemon" warning is gone, the docker stop usage message is still displayed when there are no running containers.
