第一个解决方案:

首先删除不使用的容器。 docker ps -a | grep -v Up | awk '{打印$1;}' | xargs docker rm 删除所有没有标签的容器。 Docker images | grep none | awk '{打印$3;}' | xargs docker rmi

第二种解决方案删除所有:

$ docker system prune -a


WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all images without at least one container associated to them
- all build cache

Are you sure you want to continue? [y/N]

根据docker文档，你只能列出未标记的(悬空的)图像

$ docker images -f "dangling=true"

然后将它们重定向到docker rmi命令，就像这样:

$ docker rmi $(docker images -f "dangling=true" -q) --force

注意-q参数只显示容器的数字id。

Docker系统修剪将做的把戏，它删除

- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache

但是要小心使用它!

运行以下命令，使用docker rmi删除映像

docker images --filter "dangling=true"      

这是tansadio回答的延伸:

如果你得到以下错误:

Error response from daemon: conflict: unable to delete <> (must be forced) - image is being used by stopped container <>

你可以强迫它——force:

docker images | grep none | awk '{ print $3; }' | xargs docker rmi --force

docker rmi -f $(docker images -a|awk 'NR > 1 && $2 == "" {print $3}')
