【六袆-linux】docker删除镜像；docker删除容器才能再删除镜像；docker删除容器

1.docker中删除images的命令是docker rmi，但有时候执行此命令并不能删除images

[xiaolh@ly ~]$docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
117843ade696 ed9c93747fe1 /bin/sh -c /usr/sbin 46 hours ago Up 46 hours 0.0.0.0:49153->22/tcp test_sshd

可以看出ed9c93747fe1的image被117843ade696的container使用着，所以必须首先删除该container

2.删除容器 docker rm u_id

 

[xiaolh@ly ~]$docker rm 117843ade696
Error: container_delete: Impossible to remove a running container, please stop it first
2014/03/22 16:36:44 Error: failed to remove one or more containers

 

出现错误，这是因为该container正在运行中(运行docker ps查看)，先将其关闭

3.停止正在运行的镜像

[xiaolh@ly ~]$docker stop 117843ade696
117843ade696

 

4.删除镜像

[xiaolh@ly ~]$docker rm 117843ade696
117843ade696
[xiaolh@ly ~]$docker rmi ed9c93747fe1

[xiaolh@ly ~]$docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

 

可以看出，image已经被删除。
