Kubernetes:在内部公开多种服务&在外部 [英] Kubernetes: Expose multiple services internally & externally

问题描述

我在集群中使用AKS

Am using AKS for my cluster

场景: 我们有多个API(例如在端口101、102、103上可访问的svc1，svc2和svc3). 这些API链接需要向客户端公开，并且还应在应用程序内部使用.

Scenario: We have multiple API's (say svc1, svc2 & svc3 accessible on port 101, 102, 103). These API links need to be exposed to client and are also used internally in application.

问题: 我想将其同时暴露给外部&内部负载均衡器在相同的端口上. 另外，当我在内部访问该服务时，我希望它们可以通过服务名称进行访问(例如:svc1:101)

Question: I want to expose this to both external & internal load balancer on same ports. Also when i access the service internally, i want them to be accessible by service name (Example: svc1:101)

推荐答案

好吧，我能够在不使用NodePort/ClusterIP的情况下解决此问题.

Well, I was able to fix the issue without using NodePort/ClusterIP.

解决方案非常简单，但似乎没有记录.

Solution is pretty simple but seems its not documented.

我们要做的就是拥有多个标签，其中1个标签与外部负载均衡器相同，而其他标签具有相同的匹配服务.

Only thing we have to do is have multiple tags where 1 tag is same as of external load balancer and other tag you have same matching service.

这会将您的副本集映射到服务&外部负载均衡器.

This will map your replicaset to both service & external loadbalancer.
