>docker info

效果与docker version 基本一致

docker pull 仓库:TAG

docker pull [OPTIONS] NAME[:TAG|@DIGEST]
docker pull centos:7 //拉取centos仓库标签为7的镜像

docker search 镜像名称
docker search nginx

docker images
docker images -aq 查看本地全部镜像id信息

docker image ls -aq // 查看本地全部镜像id信息

强制删除相关镜像
docker rmi -f 仓库:TAG //删除单个镜像
docker rmi -f $(docker images -ag) 通过查看所有镜像id，删除所有镜像

docker 命令 --help
