以下是搜到的幾種方案

# 停止docker
docker stop $(docker ps -a | grep "Exited" | awk '{print $1 }')
# 刪除docker
docker rm $(docker ps -a | grep "Exited" | awk '{print $1 }')
# 刪除images
docker rmi $(docker images | grep "none" | awk '{print $3}')

- 好的<none>:<none>鏡像的產(chǎn)生
例如從鏡像倉庫里拿一個(gè)fedora 鏡像。如圖雖然docker images 只顯示fedora:latest，但是
docker images -a 顯示了兩個(gè)鏡像fedora:latest 和<none>:<none>.
原來docker中鏡像是有垂直父子關(guān)系的，層級(jí)關(guān)系可以在/var/lib/docker/graph中看到。docker pull fedora執(zhí)行的時(shí)候呢，就會(huì)每次下載一個(gè)鏡像。
可以通過查看/var/lib/docker/graph的json查看父子關(guān)系。這些鏡像都不會(huì)引起存儲(chǔ)空間占用的問題。

- 壞的<none>:<none>鏡像的產(chǎn)生
而docker build 或是 pull 命令就會(huì)產(chǎn)生臨時(shí)鏡像。如果我們用dockerfile創(chuàng)建一個(gè)helloworld鏡像后，因?yàn)榘姹靖滦枰匦聞?chuàng)建，那么以前那個(gè)版本的鏡像就會(huì)
成為臨時(shí)鏡像。這個(gè)是需要?jiǎng)h除的。刪除命令見下。
sudo docker rmi $(docker images -f "dangling=true" -q)
