Hi Jirka, it looks like cgroups are not mounted for docker. This is more like cockpit issue. Can you run ls /sys/fs/cgroup/ on the f21 machine and inside docker? Jan
Hey, Jan here you go: [root@fidora-minimal-remix ~]# ls /sys/fs/cgroup/ blkio cpu cpuacct cpu,cpuacct devices freezer net_cls systemd
Thanks Jirka. This looks like cockpit is running docker without mounted cgroups.
Hi Jirka, have you tried running the docker command manually in the shell for comparison (not in cockpit)? e.g. "docker run docker.io/wordpress:latest" As far as I know we don't access cpuset from inside cockpit and we only interface with a running docker instance. If docker isn't running we offer to start it for the user, which is internally done via "systemctl start docker". If it works in the console and not in cockpit, could you also please test running a simple container like busybox via cockpit? Dominik
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
still receiving emails from this, I can see that this is closed, what is the best way to stop the email notifications coming?
