下面是我的docker-cleanup脚本，它删除未标记的容器和图像。请检查来源的任何更新。

#!/bin/sh
# Cleanup docker files: untagged containers and images.
#
# Use `docker-cleanup -n` for a dry run to see what would be deleted.

untagged_containers() {
  # Print containers using untagged images: $1 is used with awk's print: 0=line, 1=column 1.
  docker ps -a | awk '$2 ~ "[0-9a-f]{12}" {print $'$1'}'
}

untagged_images() {
  # Print untagged images: $1 is used with awk's print: 0=line, 3=column 3.
  # NOTE: intermediate images (via -a) seem to only cause
  # "Error: Conflict, foobarid wasn't deleted" messages.
  # Might be useful sometimes when Docker messed things up?!
  # docker images -a | awk '$1 == "<none>" {print $'$1'}'
  docker images | tail -n +2 | awk '$1 == "<none>" {print $'$1'}'
}

# Dry-run.
if [ "$1" = "-n" ]; then
  echo "=== Containers with uncommitted images: ==="
  untagged_containers 0
  echo

  echo "=== Uncommitted images: ==="
  untagged_images 0

  exit
fi

# Remove containers with untagged images.
echo "Removing containers:" >&2
untagged_containers 1 | xargs --no-run-if-empty docker rm --volumes=true

# Remove untagged images
echo "Removing images:" >&2
untagged_images 3 | xargs --no-run-if-empty docker rmi

官方的说法是:

docker rm `docker ps -aq`

Docker的维护者已经表示不会有这样的命令——你可以像这样组合命令:

我们之前讨论过这个问题，希望用户使用上面的代码行，而不必向Docker添加额外的代码。

对于感兴趣的人，我从qkrijger中取了一个例子，并将其转换为clear all(停止并删除所有)

docker stop `docker ps --no-trunc -aq` ; docker rm `docker ps --no-trunc -aq`

你可以停止docker容器，一旦停止，你可以删除容器。

停止容器:

$ docker stop "containerID" -你也可以提到容器ID的前两个字母，它是有效的。

取出容器

$ docker rm "containerID" -同样你也可以提到容器的前两个字母

如果这些命令不让你停止/删除容器，m，确保你有sudo访问docker主机。

对于Linux安装，请确保使用sudo。另外，寻找几个月或几周前的图像也很好:

sudo docker ps -a | grep 'weeks ago\|months ago' | \
    awk '{print $1}' | xargs --no-run-if-empty sudo docker rm

一个伟大的自动替代- containrrr/watchtower

它包含图像自动清理，更新和监控选项
