这里看到了version     Show the Docker version information　　　即：显示docker版本信息,上一篇在介绍docker安装时已经使用过

docker version

可以看到docker的版本号为17.04.0-ce

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝镜像的操作＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

1:要介绍的镜像参数：

(1)search      Search the Docker Hub for images

(2) pull        Pull an image or a repository from a registry

(3)push        Push an image or a repository to a registry　　

(4)image       Manage images

(5)save        Save one or more images to a tar archive (streamed to STDOUT by default)

(6)load        Load an image from a tar archive or STDIN

(7)commit      Create a new image from a container's changes

(8)tag         Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE

......未完待续.....``````````````````````

(1)搜索镜像，docker提供了一个镜像中心，dockerhub，我们可以在https://hub.docker.com/注册一个账号，然后在本地登录，将本地镜像上传至我们的账号上。

      eg：使用docker login  登录自己的dockerhub账号，当然不管登录是否成功都可以搜索到dockerhub中的镜像，比如我之前上传的android 源码编译的镜像
