3、运行私服库Registry，相当于本地有一个私服 Docker Hub

[root@gh ~]# docker run -d -p 8081:5000 --name myregistry -v /home/gh/myregistry:/temp/registry --privileged=true registry

4、cul验证私服库上有什么镜像

# 发现私服仓库为空  新建
[root@gh ~]# curl -XGET http://xxx.xxx.xxx.xxx[服务器端口]:8081/v2/_catalog
{"repositories":[]}

5、将镜像修改符合私服规范的Tag

[root@gh ~]# docker tag mytomcat:1.1 xxx.xxx.xxx.xxx[服务器端口]:8081/mytomcat:1.2
[root@gh ~]# docker images
REPOSITORY                     TAG       IMAGE ID       CREATED        SIZE

6、 修改配置文件使之支持http

7、push推送到私服库

8、curl验证私服库上有什么镜像

[root@gh ~]# curl -XGET http://xxx.xxx.xxx.xxx[容器ip]:8081/v2/_catalog
{"repositories":["mytomcat"]}

9、pull到本地并运行

[root@gh myregistry]# docker pull xxx.xxx.xxx.xxx[容器ip]:8081/mytomcat:1.2
