I just installed docker then start the service and check the status. It said "Your kernel does not support cgroup rt runtime" There is bugzilla report about this http://bugzilla.redhat.com/show_bug.cgi?id=1544096 but noted as NOTABUG. I am curious what is cgroup rt runtime? Can anyone explain what it about? $ sudo systemctl status docker ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: active (running) since Tue 2018-05-29 12:49:59 +08; 7s ago Docs: http://docs.docker.com Main PID: 8017 (dockerd-current) Tasks: 18 (limit: 8192) Memory: 15.5M CGroup: /system.slice/docker.service └─8017 /usr/bin/dockerd-current --add-runtime oci=/usr/libexec/docker/docker-runc-current --default-runtime=oci --authorization-plugin=rhel-push-plugin --containerd /run/containerd.> May 29 12:49:55 robbinespu dockerd-current[8017]: time="2018-05-29T12:49:55.536963292+08:00" level=warning msg="Your kernel does not support cgroup rt runtime" May 29 12:49:55 robbinespu dockerd-current[8017]: time="2018-05-29T12:49:55.538150494+08:00" level=info msg="Loading containers: start."
