当把exec-opt native.cgroupdriver改成"cgroupfs"时，docker不能运行正确吗？
when change exec-opt native.cgroupdriver to "cgroupfs"，docker can not run correct?
my os version : centos7.3
kenerl version : 3.10.0-514.16.1.el7.x86_64
docker version : 1.12.6
我修改配置文件“/lib/systemd/system/docker.service”，将选项“--exec-opt native.cgroupdriver”从systemd更改为cgroupfs。我发现 docker 不能 运行 任何图像！
[root@surenode2 system]# cat /lib/systemd/system/docker.service |grep cgroup
--exec-opt native.cgroupdriver=cgroupfs \
[root@surenode2 system]# docker images | grep mysql

而且，如果我将 exec-opt native.cgroupdriver 更改为 systemd ，Docker 可以 运行 任何图像..
Docker 1.12.6 ("community edition") 已停产，不再受支持；
我们可以安装最新的docker版本参考'https://docs.docker.com/engine/installation/linux/centos/'。
使用最新的docker版本时，此问题不再重现！
