docker命令有很多，总的分为以下几大类：
容器生命周期管理 — docker [run|start|stop|restart|kill|rm|pause|unpause]容器操作运维 — docker [ps|inspect|top|attach|events|logs|wait|export|port]容器rootfs命令 — docker [commit|cp|diff]镜像仓库 — docker [login|pull|push|search]本地镜像管理 — 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，更详细的可以查看官网或者命令帮助
