服务不在 kubernetes 中公开

Question

我在 GKE 中有一个部署和一个服务。我将部署公开为负载均衡器，但无法通过服务（curl 或浏览器）访问它。我得到一个：

curl: (7) Failed to connect to <my-Ip-Address> port 443: Connection refused

我可以直接转发到 pod 并且工作正常：

kubectl --namespace=redfalcon port-forward web-service-rf-76967f9c68-2zbhm 9999:443 >> /dev/null

curl -k -v --request POST   --url https://localhost:9999/auth/login/   --header 'content-type: application/json'   --header 'x-profile-key: '   --data '{"email":"<testusername>","password":"<testpassword>"}'

我很可能错误配置了我的服务，但看不出如何。非常感谢对我所做的任何帮助。

服务 Yaml：

Answer 1

我明白这是什么了...

我的 golang 应用程序正在侦听本地主机而不是 0.0.0.0。这意味着 kubectl 上的端口转发有效，但任何服务公开都不起作用。

我不得不在我的 k8s 命令中添加“--host 0.0.0.0”，然后它会监听来自本地主机外部的请求。

我的命令最终是...

"./server --port 8080 --host 0.0.0.0"
