运行docker镜像时出如下错误：

docker: Error response from daemon: OCI runtime create failed: systemd cgroup flag passed, but systemd support for managing cgroups is not available: unknown.

cat daemon.json

{

  "registry-mirrors": ["https://registry.docker-cn.co"],

  "exec-opts": ["native.cgroupdriver=systemd"]

}

因为指定了systemd，导致文件docker 运行镜像失败，

解决方法，去掉

 "exec-opts": ["native.cgroupdriver=systemd"]

重启docker 服务

service docker restart
