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。

docker rm `docker ps -aq`

or

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

Docker系统修剪-a

(系统会要求您确认命令。使用-f强制运行，如果你知道你在做什么。)

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

如果你自己构建这些修剪过的映像(从其他一些较旧的基础映像)，请谨慎使用上述基于docker image prune的可接受解决方案，因为该命令是生硬的，并将尝试删除最新映像所需的所有依赖关系(该命令可能应该重命名为docker image*s* prune)。

我为我的docker映像构建管道(其中有每日构建和标签=日期YYYYMMDD格式)提出的解决方案是:

# carefully narrow down the image to be deleted (to avoid removing useful static stuff like base images)
my_deleted_image=mirekphd/ml-cpu-py37-vsc-cust

# define the monitored image (tested for obsolescence), which will be usually the same as deleted one, unless deleting some very infrequently built image which requires a separate "clock"
monitored_image=mirekphd/ml-cache

# calculate the oldest acceptable tag (date)
date_week_ago=$(date -d "last week" '+%Y%m%d')

# get the IDs of obsolete tags of our deleted image
# note we use monitored_image to test for obsolescence
my_deleted_image_obsolete_tag_ids=$(docker images --filter="before=$monitored_image:$date_week_ago" | grep $my_deleted_image | awk '{print $3}')

# remove the obsolete tags of the deleted image
# (note it typically has to be forced using -f switch)
docker rmi -f $my_deleted_image_obsolete_tag_ids

根据文档，下面的命令将删除超过48小时的图像。

$ docker image prune --all --filter until=48h
