问题
Am using AKS for my cluster
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.
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)
回答1:
In Kubernetes:
- if you want to expose something internally only, you should use ClusterIP service type
- if you want to expose both internally & externally, use LoadBalancer (or NodePort) service type.
Please check Kubernetes: Service Types for more details.

Well, I was able to fix the issue without using NodePort/ClusterIP.
Solution is pretty simple but seems its not documented.
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.
This will map your replicaset to both service & external loadbalancer.
