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

从Windows shell中删除所有容器:

FOR /f "tokens=*" %i IN ('docker ps -a -q') DO docker rm %i

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

我用的是:

docker rm -v $(docker ps -a -q -f status=exited)

删除已退出的容器:

docker rmi -f $(docker images | grep "<none>" | awk "{print \$3}")

为了摆脱所有未标记的图像。

使用实例删除已退出的容器。

docker rm $(sudo docker ps -a | grep Exit | cut -d ' ' -f 1)

以下是删除docker上旧图像的完整要点:

首先，在试图删除容器之前停止运行它们

移除正在运行的容器

docker rm $(docker stop -t=1 $(docker ps -q))

你可以用kill代替stop。在我的情况下，我更喜欢停止，因为我倾向于重新运行它们，而不是每次都创建一个新的，所以我试图很好地关闭它们。

注意:试图停止一个容器会给你一个错误:

错误:无法移除正在运行的容器，请先停止它

移除所有容器

docker rm $(docker ps -a -q)
