# 查看正在运行的容器
docker ps
# 查看全部的容器，包括已经停止运行的
docker ps -a

docker stop 容器id

docker rm 容器id

# 查看正在运行的镜像
docker iamges
# 查看全部的镜像，包括已经停止运行的
docker images -a

# 通过镜像id删除
docker rmi IMAGE ID(镜像id)
# 通过仓库名和标签删除
docker rmi REPOSITORY:TAG(仓库:标签)
# 删除异常停止的docker容器
docker rm `docker ps -a | grep Exited | awk '{print $1}'`   
# 删除名称或标签为none的镜像
docker rmi -f  `docker images | grep '<none>' | awk '{print $3}'`
