在虚拟机上通过Docker Compose部署了一个Harbor服务，通过Nginx反向代理了Harbor服务，实现可以通过域名访问Harbor。

通过配置的外网域名进行镜像的推送，镜像推送到一半，直接出现unknown blob，通过IP直接推送到Harbor仓库则没问题。

解决方案如下，参考Issue

sudo vi common/config/registry/config.yml

在http的配置下面，新增relativeurls: true配置项：

http:
  # Add the following line
  relativeurls: true

然后重启Harbor：

sudo docker compose restart
# Or
sudo docker-compose restart

这个Issue也有说明，每次运行install.sh都会重新覆盖该文件，也就是说都得重新修改该配置。

Note: You should do this every time after you run the install.sh script, as install.sh will overwrite all files under the common directory.
