在Docker使用中,经常会碰到删除镜像不成功,反而让镜像变成了<none > <none>即,没名字,没Tag的镜像。

好多<none>,删又删不了。这主要是一些container使用了该image导致的,不仅仅是说现在运行的容器,之前运行的也会。

docker ps -a

可以查历史记录,然后将container commit成镜像。

我们需要删除这些依赖Image的container,当使用到该镜像的所有container都删除了,就可以直接用IMAGE_ID来删除该镜像。

好,删除干净了。还我们一个干净的工作区间。



docker的删除有两种,一个是rm 删除容器,一个是rmi删除镜像。

rm Remove one or more containers
rmi Remove one or more images

这里有两个不同的单词,imagescontainer。其中images很好理解,跟平常使用的虚拟机的镜像一个意思,相当于一个模版,而container则是images运行时的的状态。docker对于运行过的image都保留一个状态(container),可以使用命令docker ps来查看正在运行的container,对于已经退出的container,则可以使用docker ps -a来查看。 如果你退出了一个container而忘记保存其中的数据,你可以使用docker ps -a来找到对应的运行过的container使用docker commit命令将其保存为image然后运行。

回到之前的问题,由于image被某个container引用(拿来运行),如果不将这个引用的container销毁(删除),那image肯定是不能被删除。

所以想要删除运行过的images必须首先删除它的container。继续来看刚才的例子,

[yaxin@ubox ~]$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

[yaxin@ubox ~]$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

[yaxin@ubox ~]$docker stop 117843ade696
117843ade696
[yaxin@ubox ~]$docker rm 117843ade696

可以看出,image已经被删除
