K8S中Harbor使用Nginx反向代理没法获取image

问题：Kubernetes建立Pod失败，没法获取image

Failed create pod sandbox: rpc error: code = Unknown desc = failed pulling image "harbor.od.com/public/pause:latest": Error response from daemon: Get http://harbor.od.com/v2/public/pause/manifests/latest: Get http://harbor.od.com:180/service/token?scope=repository%3Apublic%2Fpause%3Apull&service=harbor-registry: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers

环境：
harbor.od.com二进制包安装，使用docker-compose启动，
harbor.yaml配置port：180
而后经过部署nginx，反向到后端harbor上

故障排查：

1.使用docker pull 仓库镜像也没法获取

Error response from daemon: Get http://harbor.od.com/v2/public/pause/manifests/latest: Get http://harbor.od.com:180/service/token?scope=repository%3Apublic%2Fpaue%3Apull&service=harbor-registry: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

2.使用docker loginx登陆Harbor

Error response from daemon: Get https://harbor,od,com/v2/: dial tcp: lookup harbor,od,com: no such host

3.修改为使用IP的方式登陆Harbor

 

Error response from daemon: Get http://harbor.od.com/v2/: Get http://harbor.od.com:180/service/token?account=admin&client_id=docker&offline_token=true&service=habor-registry: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

分析问题：

docker使用Http请求获取镜像，harbor是经过nginx的80端口访问，可是经过Log上看到的是使用Get方式，另外还要带有域名加180端口方式验证，应该是配置问题引发

解决问题：
修改harbor.yml配置文件，取消external_url注释，设置为：

external_url: http://harbor.od.com:80
而后，docker-compose down中止全部服务，删除当前配置目录：rm -rf ./common/config下配置清单，从新执行install.sh生成配置，便可解决

配置大概解释：若是使用外部代理就要启动该项# Uncomment external_url if you want to enable external proxy# And when it enabled the hostname will no longer used
