我在CentOS 7中安装了docker，当我运行时
[root@hk-qa-linux-2 ~]# docker daemon
我得到以下
INFO[0000] libcontainerd: new containerd process, pid: 611
ERRO[0001] 'overlay' not found as a supported filesystem on this host. Please ensure kernel is new enough and has overlay support loaded.
INFO[0001] Graph migration to content-addressability took 0.00 seconds
WARN[0001] Your kernel does not support cgroup memory limit

WARN[0001] Unable to find cpuset cgroup in mounts
WARN[0001] mountpoint for pids not found
FATA[0001] Error starting daemon: Devices cgroup isn't mounted
当我检查文件安装时，我可以看到cgroup
[root@hk-qa-linux-2 cgroup]# df

不确定如何解决此问题。任何建议都会有所帮助
