摘要：以下都會(huì)使用到容器，所以執(zhí)行以下指令查看容器或者容器名稱(chēng)檢查環(huán)節(jié)變量查看日志備份恢復(fù)備份使用進(jìn)入容器沒(méi)有剩余磁盤(pán)空間使用以下指令刪除容器和鏡像刪除所有容器刪除未使用的鏡像清理日

以下都會(huì)使用到容器 id，所以執(zhí)行以下指令查看容器 id 或者容器名稱(chēng)

[yexiaobaideMacBook-Pro: ~]$ sudo docker ps 
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS                              NAMES

sudo docker inspect --format "{{.Config.Env}}" abf7cdbe5d1c

sudo docker logs -f abf7cdbe5d1c

sudo docker run --rm -v /tmp:/backup --volumes-from  busybox tar -cvf /backup/backup.tar 

恢復(fù)備份

sudo docker run --rm -v /tmp:/backup --volumes-from  busybox tar -xvf /backup/backup.tar 

sudo docker exec -it ecstatic_morse  bash

使用以下指令刪除容器和鏡像

sudo docker ps -aq | xargs sudo docker rm # 刪除所有容器
sudo docker images -aq -f dangling=true | xargs sudo docker rmi # 刪除未使用的鏡像

清理日志 - 非 root 權(quán)限

 sudo su -c "echo "" > $(sudo docker inspect --format="{{.LogPath}}" ecstatic_morse)"      

在 .zshrc 或者 .bashrc 中寫(xiě)入以下腳本：

alias dockercleancontainers="docker ps -aq | xargs docker rm"
alias dockercleanimages="docker images -aq -f dangling=true | xargs docker rmi"
alias dockerclean="dockercleancontainers && dockercleanimages"
alias docker-killall="docker ps -q | xargs docker kill"
