Question

Is a newly created Docker container associated with a new cgroup?

After all the processes inside a container finishes running, and the container is restarted again sometime later, will it be associated with a new cgroup or still the same cgroup as before?

Answer 1

Yes, and that is most probably under system.slice. You can change the slice for all docker containers.

This can be viewed using systemd-cgls , or check for cat /proc/PROCESS_ID/cgroup
