查看docker镜像
docker images
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker images

从镜像仓库查询镜像
Docker Hub 的地址是：hub.docker.com/
镜像仓库搜索结果.png
在 Docker Hub 的搜索结果中，有几项关键的信息有助于我们选择合适的镜像：
OFFICIAL 代表镜像为 Docker 官方提供和维护，相对来说稳定性和安全性较高
Stars 代表镜像的关注人数，这类似 GitHub 的 Stars，可以理解为热度
Downloads 代表镜像被拉取的次数，基本上能够表示镜像被使用的频度
除了直接通过 Docker Hub 网站搜索镜像这种方式外，我们还可以用 docker CLI 中的 docker search 这个命令搜索 Docker Hub 中的镜像。
docker search mysql
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker search mysql

管理镜像
除了使用docker images查看镜像列表以外 还可以使用 docker inspect （容器ID或镜像ID） 查看镜像详情
docker inspect mysql/990386cbd5c0
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker inspect mysql
[
{

删除镜像
docker rmi （镜像ID或名称） 支持同时删除多个镜像
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker rmi ubuntu
