docker images
2、查看正在运行的容器
docker ps
3、查看所有容器
docker ps -a 
4、运行已存在的容器
docker start {id} 
5、停止已存在的容器
docker stop {id} 
6、删除容器 （必须先停止容器）
docker rm {容器id}  
7、删除镜像
docker rmi {镜像id} 
8、进入容器，推荐使用
docker exec -it {容器id} /bin/bash 
9、进入容器
docker attach {容器id}
10、查看容器ip：
docker inspect --format='{{.Name}} - {{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
