将 google kubernetes 引擎 (GKE) 公开为服务后无法访问该 IP
Cannot access the IP create by google kubernetes engine (GKE) after exposing it as service
我有一个应用程序,它将在 127.0.0.1:8080
启动服务器并使用 Dockerfile
创建一个映像以将其托管在 GKE 上。我在 kubernetes 集群的 port 8080
上部署了这个应用程序。然后我将服务暴露为 LoadBalancer
相同的端口 8080,但它不允许从外部访问它。所以我为外部访问创建了一个入口,但仍然不起作用。
当我点击 ingress 提供的 IP 时,我得到这个错误:
Error: Server Error
The server encountered a temporary error and could not complete your request.
Please try again in 30 seconds.
请问我在执行过程中有没有遗漏或做错的地方

start a server at 127.0.0.1:8080
这将允许您的应用仅接受 pod 内的连接。而是绑定到 0.0.0.0
。
还有你的部署:
