docker刪除不了鏡像：
docker rmi 45c94aceead5
Error response from daemon: conflict: unable to delete 45c94aceead5 (must be forced) - image is being used by stopped container 55881c13e4e4
說明docker容器正在啓動，不能刪除，所以要先停掉容器，而停掉容器不是簡單的stop或者kill，要做如下步驟：
先暫停正在運行中的容器：docker stop 容器ID
再清除掉容器使用的網絡： docker network disconnect --force bridge 容器ID
再強制刪除容器：docker rm -f 容器ID
> docker network disconnect --force bridge 55881c13e4e4
> docker rm -f 55881c13e4e4
> 55881c13e4e4
這時，容器已經被刪除掉了，可以刪除鏡像了：docker rmi 鏡像ID
