删除映像时，出现以下错误

Error response from daemon: conflict: unable to delete 9f8c08f4755e (must be forced) - image is referenced in multiple repositories

查看映像，确实出现大量ID相同，repository或tag不同的映像

ps images
# docker images

 参考CSDN文章：https://blog.csdn.net/JackLiu16/article/details/80581709

可以用名称删除，但这样太慢。

参考另外一篇文章https://www.cnblogs.com/q4486233/p/6482711.html中批量删除untagged images，也就是那些id为<None>的image的映像的作法，

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

将<none>替换为上面images中的模式字符 ：

docker rmi $(docker images | grep "^xproject" | awk "{print $3}")

顺序删除全部映像。

 

将该文备忘如下：
 

1.停止所有的container，这样才能够删除其中的images：

docker stop $(docker ps -a -q)

如果想要删除所有container的话再加一个指令：

docker rm $(docker ps -a -q)

2.查看当前有些什么images

docker images

3.删除images，通过image的id来指定删除谁

docker rmi <image id>

想要删除untagged images，也就是那些id为<None>的image的话可以用

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

要删除全部image的话

docker rmi $(docker images -q)
