首先，运行docker images查看图像列表，并将IMAGE HASH ID复制到剪贴板中。

运行docker rmi -f <镜像>

记住选项-f是强制删除。

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

这招对我很管用:

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

如何删除带标签的图像

Docker先取标签 Docker对图像进行了描述。 #可以在一个docker rmi调用中完成，例如:# Docker rmi <repo:tag> <imageid>

(2016年11月，Docker版本1.12.2)

e.g.

$ docker images 
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
usrxx/the-application   16112805            011fd5bf45a2        12 hours ago        5.753 GB
usryy/the-application   vx.xx.xx            5af809583b9c        3 days ago          5.743 GB
usrzz/the-application   vx.xx.xx            eef00ce9b81f        10 days ago         5.747 GB
usrAA/the-application   vx.xx.xx            422ba91c71bb        3 weeks ago         5.722 GB
usrBB/the-application   v1.00.18            a877aec95006        3 months ago        5.589 GB

$ docker rmi usrxx/the-application:16112805 && docker rmi 011fd5bf45a2
$ docker rmi usryy/the-application:vx.xx.xx && docker rmi 5af809583b9c
$ docker rmi usrzz/the-application:vx.xx.xx eef00ce9b81f
$ docker rmi usrAA/the-application:vx.xx.xx 422ba91c71bb
$ docker rmi usrBB/the-application:v1.00.18 a877aec95006

例:脚本删除超过2周的内容。

IMAGESINFO=$(docker images --no-trunc --format '{{.ID}} {{.Repository}} {{.Tag}} {{.CreatedSince}}' |grep -E " (weeks|months|years)")
TAGS=$(echo "$IMAGESINFO" | awk '{ print $2 ":" $3 }' )
IDS=$(echo "$IMAGESINFO" | awk '{ print $1 }' )
echo remove old images TAGS=$TAGS IDS=$IDS
for t in $TAGS; do docker rmi $t; done
for i in $IDS; do docker rmi $i; done

要删除没有容器运行的标记图像，你必须使用一个小脚本:

#!/bin/bash

# remove not running containers
docker rm $(docker ps -f "status=exited" -q)

declare -A used_images

# collect images which has running container
for image in $(docker ps | awk 'NR>1 {print $2;}'); do
    id=$(docker inspect --format="{{.Id}}" $image);
    used_images[$id]=$image;
done

# loop over images, delete those without a container
for id in $(docker images --no-trunc -q); do
    if [ -z ${used_images[$id]} ]; then
        echo "images is NOT in use: $id"
        docker rmi $id
    else
        echo "images is in use:     ${used_images[$id]}"
    fi
done

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。
