一、前提：
1.要删除image， 必须该image下没有container
2.要删除container，必须使该container处于stop状态
正文：
二、说自己成功的笨办法
1）批量停止container：
sudo docker ps -a | awk '{print $1}'| grep -v CONTAINER | xargs sudo docker stop
2）批量删除container：
sudo docker images | awk '{print $3}' | grep -v IMAGE | xargs sudo docker rmi
3）批量删除image：
sudo docker images | awk '{print $1}' | grep -v REPOSITORY | xargs sudo docker rmi
成功
三、走过的坑：
使用网上说的 sudo docker stop $(docker ps -q) 命令批量停止container——失败
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.29/containers/json: dial unix /var/run/docker.sock: connect: permission denied
"docker stop" requires at least 1 argument(s).
See 'docker stop --help'.
Usage: docker stop [OPTIONS] CONTAINER [CONTAINER...]
Stop one or more running containers
接下来使用网上说的 sudo docker rm -f `docker ps -aq` 命令批量删除container——失败（明显有没停止的，注定后面批量失败）
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.29/containers/json?all=1: dial unix /var/run/docker.sock: connect: permission denied
"docker rm" requires at least 1 argument(s).
See 'docker rm --help'.
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers
使用网上说的 sudo docker rm $(docker ps --all -q -f status=exited) 命令批量删除container——失败
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.29/containers/json?all=1&filters=%7B%22status%22%3A%7B%22exited%22%3Atrue%7D%7D: dial unix /var/run/docker.sock: connect: permission denied
"docker rm" requires at least 1 argument(s).
See 'docker rm --help'.
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers
使用网上说的 sudo docker rmi `docker images -q` 命令批量删除images——失败
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.29/images/json: dial unix /var/run/docker.sock: connect: permission denied
"docker rmi" requires at least 1 argument(s).
See 'docker rmi --help'.
Usage: docker rmi [OPTIONS] IMAGE [IMAGE...]
Remove one or more images
使用网上说的 sudo docker image prune -a 成功删掉一部分images
另外，在使用常规的删除命令docker rmi删除image时，遇到提示
Error response from daemon: conflict: unable to delete 536ade400cd9 (cannot be forced) - image has dependent child images
gitlab-runner@yue:~$ sudo docker rmi c8a528e46ad2

"docker image inspect" requires at least 1 argument(s).

Usage: docker image inspect [OPTIONS] IMAGE [IMAGE...]
Display detailed information on one or more images
此时，使用网上说的 列出所有在image之后创建的image的父image 的命令：
docker image inspect --format='{{.RepoTags}} {{.Id}} {{.Parent}}' $(docker image ls -q --filter since=xxxxx)后，失败

Display detailed information on one or more images希望和我一样遇到类似问题的人找到解决办法，也希望能有大神指点一二，谢谢！
