I installed docker 17.09.1 on openSUSE Leap 15.0 via zypper. Unfortunately starting the docker service always times out.

output of systemctl start docker:

Job for docker.service failed because a timeout was exceeded.
See "systemctl  status docker.service" and "journalctl  -xe" for details.

output of journalctl:

Oct 28 10:38:06 linux-j8zs dockerd[3786]: time="2018-10-28T10:38:06.692915975+01:00" level=warning msg="Your kernel does not support cgroup rt runtime"

Oct 28 10:41:06 linux-j8zs systemd[1]: docker.service: Failed with result 'timeout'.

What I tried:

  1. Emptying /var/lib/docker like here
  2. Adding the user to the group docker and reboot like here
  3. Starting the daemon via systemctl start docker -- like here

Any ideas how to solve this issue?

@Marph,

Journal logs clearly shows your kernel not supporting cgroup feature.

level=warning msg="Your kernel does not support cgroup rt runtime"

Try to update your kernel version and take a reboot. Once server back online your docker service will be up and running.

  • I tried to update my kernel, but it can't load the bbswitch module. I will post if I can get it working. – Marph Oct 29 '18 at 16:33
