简单说来，Harbor封装了Docker的registry v2，帮用户提供了许多便捷管理的特性，方便用户操作。
Harbor的github主页上已经讲得很详细了，在此不再赘述。
proxy: image: nginx:1.9 container_name: nginx restart: always volumes: -./common/config/nginx:/etc/nginx ports: - 9999:80 - 443:443 depends_on: - mysql - registry - ui
然后再修改common/templates/registry/config.yml文件：
auth: token: issuer:registry-token-issuer realm: $ui_url:9999/service/token rootcertbundle:/etc/registry/root.crt service: token-service
修改完成后执行sudo ./prepare重新生成配置文件
Registry端口修改（非必需）
按照惯例，开放5000端口给registry使用，则修改docker-compose.yml文件，为registry节点添加posts属性，步骤与修改Nginx配置一样，不再赘述。
增加这个
ports:
- 5000:5000

设置信赖列表
默认情况下，docker对registry的操作是基于https协议的，而Harbor默认是以http协议访问的，如果这时候执行docker login的操作，会得到这样的错误信息：
Error response from daemon: Get https://xx.xxx.xx.xx/v1/users/: dial tcp xx.xxx.xx.xx:443:getsockopt: connection refused
这时候需要修改docker的启动文件（Ubuntu16.04下，这个文件是/lib/systemd/system/docker.service），如下所示：
# Modified,origin: ExecStart=/usr/bin/dockerd -H fd:// ExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry xx.xxx.xx.xx:5000
然后执行命令：
sudo systemctl daemon-reload sudo systemctl restart docker
万事俱备，下面我们来试试上传镜像。以docker的官方镜像hello-world为例，先下载好镜像，然后给镜像打tag：
docker tag hello-world xx.xx.xx.xx:5000/test/hello-world
其中“test”为项目名，如果预先没有创建test项目的话，push的时候会提示：
denied: requested access to the resource is denied
那么现在Harbor UI里新建一个test项目，然后执行：
docker push xx.xx.xx.xx:5000/test/hello-world
大功告成！
再来看拉取镜像，启动另一台虚拟机（CentOS系统），然后输入：
docker pull xx.xx.xx.xx:5000/test/hello-world
开个玩笑，你不会真的直接这样输入吧？会报错的：
http: server gave HTTP response to HTTPS client
解决的方法也很简单，在/etc/docker/daemon.json（如果没有就新建）中添加以下代码：
{ "insecure-registries":["xx.xx.xx.xx:5000"] }
仅限于Docker 1.12+，如果使用较低版本的docker，请自行查找解决方案：）
