即使没有容器在运行也无法删除图像

Question

我的机器中有多个停止的容器和图像。
我想清理并删除所有容器：
docker ps -a什么也不返回。
我运行docker rmi $(docker images -q)删除缓存的图像，但得到：

来自守护程序的错误响应：冲突：无法删除...（必须强制执行）-在多个存储库中引用了图像

它在说什么仓库？

Answer 1

要强制删除涉及多个存储库的 Docker 镜像，只需使用以下命令：

sudo docker rmi -f image_id

Answer 2

You cannot remove images having multiple repositories without the force modifier, see Docker docs for more info.

docker images
REPOSITORY                   TAG      IMAGE ID            CREATED           SIZE
repository/image-name        tag      a8e6fa672e89        10 days ago         344MB
repository2/image-name       tag      a8e6fa672e89        10 days ago         344MB

If you want to do it manually, instead of using the image id to remove the images, you must remove the repository/tag that you don't need using image names:

docker rmi a8e6fa672e89
Error response from daemon: conflict: unable to delete a8e6fa672e89 (must be forced) - image is referenced in multiple repositories

Remove the repository/tag you don't need:

docker rmi repository/image-name:tag
Untagged: repository/image-name:tag
Untagged: repository/image-name:tag@sha256:64b5a02e2bb3ee4d4b7c0982e8e2e5eb68bdfd0fb096fce22b6c030dafb53a33

(Repeat last step until only one repository/tag remains) And now you will be able to remove the image:

docker rmi a8e6fa672e89
Untagged: repository2/image-name:tag
Deleted: sha256:a8e6fa672e89b399bd3ac52b96c031e6816a69191d1fd7e6a1839fd643e3c751
Deleted: sha256:9861dd7b5783217515f571fdcfa6729e1e38af3ae9c971026e5a317b12fc5905

If you use the -f flag and specify the image’s short or long ID, then rmi untags and removes all images that match the specified ID.

Answer 3

The "repositories" it is talking about is part of the first column of a docker images:

docker images
REPOSITORY                   TAG      IMAGE ID            CREATED           SIZE
repository/image-name        tag      a8e6fa672e89        10 days ago         344MB
repository2/image-name       tag      a8e6fa672e89        10 days ago         344MB

(I take the samples which Gabriel showed in his answer)

Here we have two repositories: "repository" and "repository2". As you also can see, both images have the same IMAGE ID.

A docker images -q lists all available IMAGE ID's. Thus if you want to remove an IMAGE ID which is referenced by two images you get the error that you have mentioned.

Solution: You can remove the image by its name instead of its ID:

docker rmi repository/image-name:tag

Answer 4

根本问题是您试图删除该图像，但该图像被标记为 Tarun Banda 所写的。因此，不要通过 id 删除图像，而是通过其标签删除图像。这将取消图像的标记，然后将其删除。

这是清理旧容器的示例：

docker images | grep '3 weeks ago' | awk '{print $1 ":" $2}' | xargs -n 1 docker rmi

Answer 5

您可以清理所有容器。首先，您需要使用以下命令停止所有容器：docker stop $(docker ps -aq)。最后，使用以下命令删除所有容器docker rm $(docker ps -aq)：您可以通过一个命令完成这一切docker rm $(docker stop $(docker ps -aq))。

如果要删除所有容器数据：

docker container prune
docker network prune
docker system prune
docker volume prune
docker builder prune
