手动删除docker图像

我有我的本地Ubuntu的大约50K的图像：

$ docker info Containers: 3 Images: 49708 Storage Driver: aufs Root Dir: /var/lib/docker/aufs Backing Filesystem: extfs Dirs: 49714 

docker rmi -f $(docker images | grep "something" | awk "{print \$3}")

采取100％的CPU，速度太慢。 有没有快速的方法来删除大量的图像？

Answer 1

所以回答我自己的问题，在docker contrib目录中有一个脚本： https ： //github.com/docker/docker/blob/620339f166984540f15aadef2348646eee9a5b42/contrib/nuke-graph-directory.sh

用sudo运行它删除了所有的图像，只需重新启动docker守护进程，你就可以走了。

Answer 2

似乎你需要清理/var/lib/docker/aufs 。 我没有这样做，这可能是不安全的。

但首先尝试使用由ndk写的这些别名：

 # Kill all running containers. alias dockerkillall='docker kill $(docker ps -q)' # Delete all stopped containers. alias dockercleanc='printf "\n>>> Deleting stopped containers\n\n" && docker rm $(docker ps -a -q)' # Delete all untagged images. alias dockercleani='printf "\n>>> Deleting untagged images\n\n" && docker rmi $(docker images -q -f dangling=true)' # Delete all stopped containers and untagged images. alias dockerclean='dockercleanc || true && dockercleani' # Delete all alias dockercleanup='dockerkillall || true && dockercleanc || true && dockercleani' 

UPD：自从这个答案发表以来，已经引入了几种新的手工清理方法。 我将允许自己引用GitHub用户adamhadani的代码（需要docker docker-py ）：

 #!/usr/bin/env python """ Check all existing Docker containers for their mapped paths, and then purge any zombie directories in docker's volumes directory which don't correspond to an existing container. """ import logging import os import sys from shutil import rmtree import docker DOCKER_VOLUMES_DIR = "/var/lib/docker/vfs/dir" def get_immediate_subdirectories(a_dir): return [os.path.join(a_dir, name) for name in os.listdir(a_dir) if os.path.isdir(os.path.join(a_dir, name))] def main(): logging.basicConfig(level=logging.INFO) client = docker.Client() valid_dirs = [] for container in client.containers(all=True): volumes = client.inspect_container(container['Id'])['Volumes'] if not volumes: continue for _, real_path in volumes.iteritems(): if real_path.startswith(DOCKER_VOLUMES_DIR): valid_dirs.append(real_path) all_dirs = get_immediate_subdirectories(DOCKER_VOLUMES_DIR) invalid_dirs = set(all_dirs).difference(valid_dirs) logging.info("Purging %s dangling Docker volumes out of %s total volumes found.", len(invalid_dirs), len(all_dirs)) for invalid_dir in invalid_dirs: logging.info("Purging directory: %s", invalid_dir) rmtree(invalid_dir) logging.info("All done.") if __name__ == "__main__": sys.exit(main())
