Question

我正在使用docker，我发现当我运行

时

<none>

我有大量没有标签的图片，或者至少它们有

标签

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

这些浪费了我磁盘上的太多空间，现在df -h告诉我我的根已经满了。

我潜伏在互联网上，发现

Error: response from daemon: Conflict, <id> wasn't deleted
Error: response from daemon: Conflict, <id> wasn't deleted 
Error: response from daemon: Conflict, <id> wasn't deleted
Error: response from daemon: Conflict, <id> wasn't deleted 
etc...
Error: failed to remove images: [<list of all the image ids that I want gone>]

至少会遍历所有无关，但随后我会得到一大堆错误信息。

FrameLayout

这有点令人讨厌。有谁知道这些没有标记的图像是什么，为什么我的命令没有摆脱它们？

Answer 1

每当您构建新版本的标记图像时（例如，运行docker build -t foo .，更改Dockerfile中的内容，然后再次运行该命令），旧图像不会被删除;它只是把它的标签带走了。您看到的<none>是没有任何标签的图像，您可以通过指定图像ID（fe336c4cdb2f或其他）来在命令中引用它们。您可以通过将这些ID传递给docker rmi来删除它们，或者您可以这样做：

docker images -f dangling=true -q | xargs -r docker rmi

如果您仍然收到有关无法删除图片的错误消息，则可能是仍有容器悬挂使用这些旧图像;通过运行docker ps -a进行检查。

Answer 2

Those <none> in REPOSITORY when you specifically do docker images -a are not meant to be deleted. Those are the internal layers that make up your image.

As suggested by @jwodder, you should delete the <none>ones which appear when you do docker images ( Note: I did not do -a ). If you see <none> in REPOSITORY when you do docker images, then you could do:
docker rmi -f $(docker images -f dangling=true -q)

If your disk space is full, try removing the images that you do not need and see when you do docker images, not with -a.

如果没有标签/ <无>标签，则无法删除泊坞窗图像
