Bug ID: 1149882 Summary: docker socket not found errors Product: Fedora Version: 20 Component: docker-io Assignee: lsm5@fedoraproject.org Reporter: bparees@redhat.com QA Contact: extras-qa@fedoraproject.org CC: admiller@redhat.com, golang@lists.fedoraproject.org, hushan.jia@gmail.com, jperrin@centos.org, lsm5@fedoraproject.org, mattdm@redhat.com, mgoldman@redhat.com, s@shk.io, thrcka@redhat.com, vbatts@redhat.com
Description of problem: When run as a service, I frequently run into issues with the /var/run/docker.sock being reported as not found, but if i shutdown the service, remove /var/run/docker.sock, and run "docker -d" manually instead, I have no such problem.
In addition, systemctl start docker does not appear to consistently create /var/run/docker.sock, though the docker daemon reports as running.
Version-Release number of selected component (if applicable): docker-io-1.2.0-2.fc20.x86_64
How reproducible: Intermittent, most consistently recreates when bind mounting the docker socket into a docker container and trying to perform docker operations from within that container.
Additional info: Disabling selinux has no effect on the results.
Sample output:
running as a service:
[bparees@bparees ~]$ ps ax | grep docker 10731 ? Ssl 0:00 /usr/bin/docker -d -H fd:// --selinux-enabled 11021 pts/6 S+ 0:00 grep --color=auto docker [bparees@bparees ~]$ ls -l /var/run/docker* -rw-r--r--. 1 root root 5 Oct 6 16:08 /var/run/docker.pid [bparees@bparees ~]$ docker ps 2014/10/06 16:10:03 Get http:///var/run/docker.sock/v1.14/containers/json: dial unix /var/run/docker.sock: no such file or directory

--- Comment #1 from Daniel Walsh dwalsh@redhat.com --- The socket should be created by the systemd if docker.socket is enabled.

--- Comment #2 from Lokesh Mandvekar lsm5@fedoraproject.org --- Ben, could you check if things work better after a 'systemctl restart docker.socket' ?
fwiw, this seems to work best on my rawhide machine. I stopped docker and rm'd docker.sock prior to below steps.

--- Comment #3 from Eric Paris eparis@redhat.com --- A little bit of systemd knowledge was dropped on my and I have this working now. I'll try to get patches everywhere tomorrow. Below look good? Socket activation works. Service enablement works. Deleting the /var/run/docker.sock is fine the next time you restart the docker.socket or start the docker.service. But for now, sleep.
