一、上次到阿里云服务器
1、制作一个带有vim功能的Ubuntu镜像
2、在阿里云上面创建镜像仓库
3、从阿里云仓库中上传和拉取镜像
二、上传镜像到本地私有库registry
1、下载镜像docker registry
2、运行私有库registry，相当于本地有个私有docker hub。
3、制作一个带有ifconfig的Ubuntu镜像
4、curl验证私有仓库有什么镜像
5、将镜像修改符合私有库规范的tag
6、修改配置文件使之支持http
7、push推送到私服库
8、再次curl验证私服库有什么镜像
9、pull到本地并运行

docker run -it ubuntu
root@8b9f2522faa0:/# apt-get update #先更新一下软件包列表
root@8b9f2522faa0:/# apt-get install vim -y
root@8b9f2522faa0:/# echo "hello world" > abc.tec #随便添加一点信息
root@8b9f2522faa0:/# cat abc.tec
hello world
按下Ctrl+p+q退出容器，容器不停止（如果直接使用exit，容器会停止运行，这样就不能制作镜像了）
# docker ps

3、从阿里云仓库中上传和拉取镜像
直接复制示例中的代码

二、上传镜像到本地私有库registry
1、下载镜像docker registry
# docker pull registry2、运行私有库registry，相当于本地有个私有docker hub。
docker run -d -p 5000:5000 -v /yoyo/myregistry/:/tmp/registry --privileged=true registry3、制作一个带有ifconfig的Ubuntu镜像

4、curl验证私有仓库有什么镜像
# curl -XGET http://192.168.80.172:5000/v2/_catalog
{"repositories":[]}
5、将镜像修改符合私有库规范的tag
# docker images

6、修改配置文件使之支持http
# vim /etc/docker/daemon.json
, "insecure-registries":["192.168.80.172:5000"] #重点逗号
#重启docker
7、push推送到私服库
# docker run -d -p 5000:5000 -v /yoyo/myregistry/:/tmp/registry --privileged=true registry

#重新启用私服库
# docker push 192.168.80.172:5000/ifubuntu:3.24

8、再次curl验证私服库有什么镜像
# curl -XGET http://192.168.80.172:5000/v2/_catalog
{"repositories":["ifubuntu"]}
9、pull到本地并运行
