docker命令有很多，總的分為以下幾大類：
容器生命周期管理 — docker [run|start|stop|restart|kill|rm|pause|unpause] 容器操作運維 — docker [ps|inspect|top|attach|events|logs|wait|export|port] 容器rootfs命令 — docker [commit|cp|diff] 鏡像倉庫 — docker [login|pull|push|search] 本地鏡像管理 — docker [images|rmi|tag|build|history|save|import] 其他命令 — docker [info|version]
以上只是日常中大部分使用的命令，更詳細的可以查看官網或者命令幫助
