要删除超过一个月的旧标记图像:

$ docker images --no-trunc --format '{{.ID}} {{.CreatedSince}}' \
    | grep ' months' | awk '{ print $1 }' \
    | xargs --no-run-if-empty docker rmi

注意，它将无法删除容器使用的图像，在存储库中引用，有依赖的子图像…这可能是你想要的。否则只需添加-f标志。

/etc/cron.示例每日/ docker-gc脚本:

#!/bin/sh -e

# Delete all stopped containers (including data-only containers).
docker ps -a -q --no-trunc --filter "status=exited" | xargs --no-run-if-empty docker rm -v

# Delete all tagged images more than a month old
# (will fail to remove images still used).
docker images --no-trunc --format '{{.ID}} {{.CreatedSince}}' | grep ' months' | awk '{ print $1 }' | xargs --no-run-if-empty docker rmi || true

# Delete all 'untagged/dangling' (<none>) images
# Those are used for Docker caching mechanism.
docker images -q --no-trunc --filter dangling=true | xargs --no-run-if-empty docker rmi

# Delete all dangling volumes.
docker volume ls -qf dangling=true | xargs --no-run-if-empty docker volume rm

你可以使用sparrow插件docker-remove-dangling-images来清理停止的容器和未使用的(悬挂的)图像:

运行docker-remove-dangling-images

它适用于Linux和Windows操作系统。

我正在使用这个命令:

export BEFORE_DATETIME=$(date --date='10 weeks ago' +"%Y-%m-%dT%H:%M:%S.%NZ")
docker images -q | while read IMAGE_ID; do
    export IMAGE_CTIME=$(docker inspect --format='{{.Created}}' --type=image ${IMAGE_ID})
    if [[ "${BEFORE_DATETIME}" > "${IMAGE_CTIME}" ]]; then
        echo "Removing ${IMAGE_ID}, ${BEFORE_DATETIME} is earlier then ${IMAGE_CTIME}"
        docker rmi -f ${IMAGE_ID};
    fi;
done

这将删除创建时间大于10周的所有映像。

其他答案都很棒，具体来说:

docker system prune # doesn't clean out old images
docker system prune --all # cleans out too much

但我需要在两个命令中间的一些东西，所以过滤器选项是我所需要的:

docker image prune --all --filter "until=4320h" # delete images older than 6 months ago; 4320h = 24 hour/day * 30 days/month * 6 months

参考:https://docs.docker.com/config/pruning/#prune-images

docker rm `docker ps -aq`

or

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