解决Error response from daemon: conflict: unable to delete bf6a13bd36ca (must be forced)

在删除REPOSITORY为none的docker镜像时，报如下Error错误：

[root@dms-npm smart]# docker images|grep none|awk '{print $3 }'|xargs docker rmi
Error response from daemon: conflict: unable to delete bf6a13bd36ca (must be forced) - image is being used by stopped container 83ef6f249283
Error response from daemon: conflict: unable to delete c708b5be204f (must be forced) - image is being used by stopped container 6f753e89c2d8

原因是这个镜像已经作为容器启动运行过，需要先删除容器，再删除镜像。
使用docker ps -a查看所有的容器

[root@dms-npm smart]# docker ps -a

删除container_id为 83ef6f249283和6f753e89c2d8的容器

[root@dms-npm smart]# docker rm 83ef6f249283
83ef6f249283
[root@dms-npm smart]# docker rm 6f753e89c2d8
6f753e89c2d8

再删除镜像可成功删除

[root@dms-npm smart]# docker images | grep none | awk '{FS=" "} {print $3}'| xargs -n 1 docker rmi $1

查看所有的镜像，发现REPOSITORY为none的镜像已经全部删除掉

[root@dms-npm smart]# docker images

强制删除镜像，加上-f参数即可

[root@dms-npm smart]# docker rmi -f af6ea583294b
