How to implement internal HTTPS proxy for traffic inside kubernetes cluster?

8/5/2021

We have two services deployed in the cluster. For compliance we need to enable these services to send HTTPS requests to each other even though they are both inside the cluster.

Constraints: 1. We cannot use Ingress as there is no external LoadBalancer in the on prem server and we also can't use Ingress in NodePort mode. 2. Cannot handle traffic encryption/decryption in the application end.
