只需简单地使用:

docker rmi <image:tag> -f

例如:

docker rmi ubuntu:latest -f 

将删除标签名为latest的映像名称ubuntu， -f是强制删除。

这对我很有效

正在删除镜像id: b721d1cdaac7

 docker rmi b721d1cdaac7 -f

响应:来自守护进程的错误响应:冲突:无法删除b721d1cdaac7(不能强制)- image有依赖的子映像

删除所有子映像

docker image rm $(docker images --filter since=b721d1cdaac7 -q) -f

正如这里所解释的，我使用以下方法来识别依赖图像并删除它们，

image_id=123456789012

docker images -a -q --filter since=$image_id |
xargs docker inspect --format='{{.Id}} {{.Parent}}'

你会看到类似这样的输出:

sha256:f7ef19862215ec0bf7a6b103504d213e1c001691703808f4154689cfbb5f14f9 sha256:a7d2efad2847bd10e5223980ed80f5781c716eddbf6131a3cf97614e7f2db97f

然后你可以逐个删除这些图片，如下所示:

docker image rm f7ef19862215ec0bf7a6b103504d213e1c001691703808f4154689cfbb5f14f9

输出类似如下所示的内容:

# docker rm $(docker ps -aq)

之后，按照阮的建议使用命令。

下面是一个脚本，用于删除一个图像和依赖于它的所有图像。

#!/bin/bash

if [[ $# -lt 1 ]]; then
    echo must supply image to remove;
    exit 1;
fi;

get_image_children ()
{
    ret=()
    for i in $(docker image ls -a --no-trunc -q); do
        #>&2 echo processing image "$i";
        #>&2 echo parent is $(docker image inspect --format '{{.Parent}}' "$i")
        if [[ "$(docker image inspect --format '{{.Parent}}' "$i")" == "$1" ]]; then
            ret+=("$i");
        fi;
    done;
    echo "${ret[@]}";
}

realid=$(docker image inspect --format '{{.Id}}' "$1")
if [[ -z "$realid" ]]; then
    echo "$1 is not a valid image.";
    exit 2;
fi;
images_to_remove=("$realid");
images_to_process=("$realid");
while [[ "${#images_to_process[@]}" -gt 0 ]]; do
    children_to_process=();
    for i in "${!images_to_process[@]}"; do
        children=$(get_image_children "${images_to_process[$i]}");
        if [[ ! -z "$children" ]]; then
            # allow word splitting on the children.
            children_to_process+=($children);
        fi;
    done;
    if [[ "${#children_to_process[@]}" -gt 0 ]]; then
        images_to_process=("${children_to_process[@]}");
        images_to_remove+=("${children_to_process[@]}");
    else
        #no images have any children. We're done creating the graph.
        break;
    fi;
done;
echo images_to_remove = "$(printf %s\n "${images_to_remove[@]}")";
indices=(${!images_to_remove[@]});
for ((i="${#indices[@]}" - 1; i >= 0; --i)) ; do
    image_to_remove="${images_to_remove[indices[i]]}"
    if [[ "${image_to_remove:0:7}" == "sha256:" ]]; then
        image_to_remove="${image_to_remove:7}";
    fi
    echo removing image "$image_to_remove";
    docker rmi "$image_to_remove";
done

找到图像id和父id的所有图像之后创建的图像问题如下:

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since=<image_id> -q)

然后调用command:

docker rmi {sub_image_id} 

sub_image_id为从属图像ID
