docker 清理 等常用命令

查看正在運行的所有容器(Container)

docker ps -a

殺死所有正在運行的容器（此命令危險，請謹慎使用）

docker kill $(docker ps -a -q)

查看所有鏡像

docker images

刪除所有鏡像

docker rmi $(docker images -q)

通過鏡像的id來刪除指定鏡像

#可以刪除多個image,image id使用空格隔開,例如: docker rmi image_id_1 image_id_2 image_id_3
docker rmi <image id>

刪除所有未打 dangling 標籤的鏡像

docker rmi $(docker images -q -f dangling=true)

爲這些命令創建別名

# ~/.bash_aliases

# 殺死所有正在運行的容器.
alias dockerkill='docker kill $(docker ps -a -q)'

# 刪除所有已經停止的容器.
alias dockercleanc='docker rm $(docker ps -a -q)'

# 刪除所有未打標籤的鏡像.
alias dockercleani='docker rmi $(docker images -q -f dangling=true)'

# 刪除所有已經停止的容器和未打標籤的鏡像.
alias dockerclean='dockercleanc || true && dockercleani'

停止、啓動、殺死一個容器

docker stop <容器名orID>
docker start <容器名orID>
docker kill <容器名orID>

實時查看容器日誌

docker logs -f <容器名orID>

快速清理docker資源 刪除沒有使用的鏡像

docker  system prune

WARNING! This will remove:
        - all stopped containers
        - all networks not used by at least one container
        - all dangling images
        - all build cache
