K8S中Harbor使用Nginx反向代理沒法獲取image

問題：Kubernetes建立Pod失敗，沒法獲取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

環境：
harbor.od.com二進制包安裝，使用docker-compose啓動，
harbor.yaml配置port：180
而後經過部署nginx，反向到後端harbor上

故障排查：

1.使用docker pull 倉庫鏡像也沒法獲取

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登陸Harbor

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

3.修改爲使用IP的方式登陸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)

分析問題：

docker使用Http請求獲取鏡像，harbor是經過nginx的80端口訪問，可是經過Log上看到的是使用Get方式，另外還要帶有域名加180端口方式驗證，應該是配置問題引發

解決問題：
修改harbor.yml配置文件，取消external_url註釋，設置爲：

external_url: http://harbor.od.com:80
而後，docker-compose down中止全部服務，刪除當前配置目錄：rm -rf ./common/config下配置清單，從新執行install.sh生成配置，便可解決

配置大概解釋：若是使用外部代理就要啓動該項# Uncomment external_url if you want to enable external proxy# And when it enabled the hostname will no longer used
