unit1:docker 官方提供的私有仓库 registry

step1:从docker官方pull用于管理私有仓库镜像服务
    docker pull registry:2
step2:挂载仓库到本地
    docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --name myregistry registry:2
    说明：Registry服务默认会将上传的镜像保存在容器的/var/lib/registry，我们将主机的/opt/registry目录挂载到该目录，即可实现将镜像保存到主机的/opt/registry目录了
    验证挂载是否成功：浏览器访问http://127.0.0.1:5000/v2
setp3:上传镜像到私有仓库
    docker tag nginx:latest localhost:5000/nginx:latest
    docker push localhost:5000/nginx:latest
    访问 http://127.0.0.1:5000/v2/_catalog 查看私有仓库目录，可以看到刚上传的镜像了
setp4:下载私有仓库镜像
    docker pull localhost:5000/镜像名:版本号
    例如
    docker pull localhost:5000/nginx:latest

unit2:Harbor用于存储和分发Docker镜像的企业级Registry服务器

说明：harbor使用的是官方的docker registry(v2命名是distribution)服务去完成。harbor在docker distribution的基础上增加了一些安全、访问控制、管理的功能以满足企业对于镜像仓库的需求
step1:下载harbor
    https://github.com/goharbor/harbor/releases
    tar -xvf harbor-offline-installer-v1.2.2.tgz
step2:配置harbor
    非mac用户：
        非 Mac 用户只需要 修改 harbor.cfg 中的 hostname ，就可以直接通过./install.sh 就可以构建镜像，并把服务启动起来
        #hostname 改为本地ip，非 Mac OS系统 可以不指定端口
        hostname = 192.168.31.143:9090
        #设置secretkey_path 的路径为 当前目录的data下
        secretkey_path = ./data
    mac用户：
        Mac用户要配置secretkey_path 和 下面 docker-    
                    compose.yml 的修改 
setp3:安装harbor构建镜像
    ./install.sh
setp4:使用harbor
    访问：http://127.0.0.1:9090/
    默认 admin 用户的密码为 Harbor12345，可以在 harbor.cfg 进行修改
setp4:上传镜像到harbor
    docker login -u admin -p Harbor12345 127.0.0.1:9090
    说明：登录私有仓库，可以使用 admin 用户 ，也可以使用我们自己创建的具有上传权限的用户
    docker tag nginx:latest 127.0.0.1:9090/library/nginx:latest
    docker push 127.0.0.1:9090/library/nginx:latest
    说明2：访问 http://127.0.0.1:9090/harbor/projects ，在 library 项目下可以看见刚上传的 nginx镜像了
