Kubernetes:ERR_NAME_NOT_RESOLVED [英] Kubernetes: ERR_NAME_NOT_RESOLVED

问题描述

我已经在GKE中部署了mongo数据库，Spring Boot BE和Angular应用程序.我的FE服务是一个负载平衡器，它需要与我的BE连接才能获取数据，但是在浏览器中出现控制台错误: GET

I have deployed a mongo db, Spring Boot BE, Angular app within GKE. My FE service is a load balancer, it needs to connect with my BE to get data but I'm getting an console error in my browser: GET http://contactbe.default.svc.cluster.local/contacts net::ERR_NAME_NOT_RESOLVED. My FE needs to consume /contacts endpoint to get data. I'm using DNS from my BE service (contactbe.default.svc.cluster.local) within my Angular app. It is my yml file that I used to create my deployment:

我在Google上搜索了很多，但仍然没有找到如何解决此问题的方法.如果有人可以伸出援手，我将不胜感激.

I googled a lot but I still have not found how to solve this problem. I would appreciate if someone could give a hand.

控制台错误

推荐答案

我找到了解决方案.我从后端更改了服务类型.我使用的是负载均衡器，而不是ClusterIP，它可以按预期工作

I found a solution. I changed the kind of service from my Backend. Instead of ClusterIP I'm using a Load balancer, it works as expected
