正在手动删除 docker 张图像

Question

我本地有大约 50K 张图片 ubuntu:

$ 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}")

占用 100% CPU 并且速度太慢。有什么快速删除大量图片的方法吗？

Answer 1

您似乎需要清理 /var/lib/docker/aufs。我没有做，这可能是不安全的。

但首先尝试使用 ndk:

编写的这些别名

# 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：自此答案发布以来，引入了几种新的手动清理方法。我将允许自己引用 GitHub 用户 adamhadani 的代码（需要 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())

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

运行它用 sudo 删除了我所有的图像，只需重新启动 docker 守护进程就可以了。
