docker-runc not installed on system

解决方法：

[root@vm173 ~]# cat /etc/docker/daemon.json 
{
    "log-level":"warn",
    "hosts": ["unix:///var/run/docker.sock","tcp://0.0.0.0:2375"],
    "runtimes": {
        "docker-runc": {
            "path": "/usr/libexec/docker/docker-runc-current"
        }
    },
    "add-runtime": "docker-runc=/usr/libexec/docker/docker-runc-current",
    "default-runtime": "docker-runc"

}

加入上述配置后重启docker服务
