docker安装的镜像文件如何完全卸载？

1、docker ps -a查看运行的镜像进程：

root@oracle-u-a1:~# docker ps -a
CONTAINER ID   IMAGE                  COMMAND        CREATED         STATUS                          PORTS     NAMES
5fcad40de5fc   6053537/portainer-ce   "/portainer"   5 minutes ago   Restarting (1) 28 seconds ago             prtainer
528bed031a7a   hello-world            "/hello"       24 hours ago    Exited (0) 24 hours ago                   flamboyant_matsumoto

2、docker stop CONTAINER ID例如要删除mysql镜像，停止该镜像进程：

root@oracle-u-a1:~# docker stop 5fcad40de5fc
5fcad40de5fc

3、docker rm CONTAINER ID卸载镜像：

root@oracle-u-a1:~# docker rm 5fcad40de5fc
5fcad40de5fc

4、docker images 查看当前docker的镜像IMAGE ID：

root@oracle-u-a1:~# docker images
REPOSITORY             TAG       IMAGE ID       CREATED        SIZE
6053537/portainer-ce   latest    0c8284f681fe   5 weeks ago    245MB
hello-world            latest    18e5af790473   2 months ago   9.14kB

5、docker rmi IMAGE ID 删除镜像：

root@oracle-u-a1:~# docker rmi 0c8284f681fe
