docker删除中间镜像

执行docker build的时候，经常会产生一些中间镜像，执行docker iamges -a可以看到。

coffee@myserver:/home/coffee$ sudo docker images -a

如果直接用命令

sudo docker rmi $(sudo docker images --filter dangling=true -q)

容易出现报错：

coffee@myserver:/home/coffee$ sudo docker rmi $(sudo docker images --filter dangling=true -q)
Error response from daemon: conflict: unable to delete 8684a0a8943f (must be forced) - image is being used by stopped container ecbd5ade37e8
Error response from daemon: conflict: unable to delete c90d308e2c8c (must be forced) - image is being used by stopped container 871bd66088c4
Error: failed to remove images: [8684a0a8943f c90d308e2c8c]

此时需要先停止并删除容器，依次执行以下命令

sudo docker ps -a | grep "Exited" | awk '{print $1 }'|xargs sudo docker stop
sudo docker ps -a | grep "Exited" | awk '{print $1 }'|xargs sudo docker rm
sudo docker images|grep none|awk '{print $3 }'|xargs sudo docker rmi

就可以删除docker build产生的临时镜像。
