查询本机的版本：

[root@localhost ~]# docker --version
Docker version 19.03.0-rc2, build f97efcc

[root@localhost ~]# docker images

[root@localhost ~]# docker run hello-world
docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "process_linux.go:430: container init caused \"write /proc/self/attr/keycreate: permission denied\"": unknown.
