We have deployed our Micro-services in Azure Kubernetes Services using Dockers and it has a InGress Controller to route the calls. ref:https://docs.microsoft.com/en-us/azure/aks/ingress

We are protecting the public end point with a SSL Certificate but We want to know is there a way to encrypt the communication happening within the Kubernetes Clusters i.e. between Micro-services. Most of the Microsoft documentation was referring to Nginx implmenetations and nothing beyond that..

Any help will be really appreciated, thanks in advance,

Regards JK
