單個容器操做

[root@sys ~]#docker  start 3ad7725a72f3 #啓動某個容器
[root@sys ~]#docker  stop 3ad7725a72f3  #關閉某個容器

刪除操做

[root@sys ~]# docker rmi nginx   #刪除鏡像
[root@sys ~]# docker rm 08a40f59bf14  #刪除容器

---

批量容器操做

[root@sys ~]#docker kill $(docker ps -a -q) #殺死全部正在運行的容器
[root@sys ~]#docker rm $(docker ps -a -q)  #刪除全部已經中止的容器
[root@sys ~]#docker rmi $(docker images -q)#刪除全部鏡像
[root@sys ~]#docker rmi $(docker images -q -f dangling=true) #刪除全部未打 dangling 標籤的鏡像
[root@sys ~]#docker rmi --force $(docker images | grep doss-api | awk '{print $3}') #強制刪除鏡像名稱中包含「doss-api」的鏡像
