How to enable SSL certificate for internal services on Kubernetes

I have some NodeJS based internal backend services running on Kubernetes. I would like to use a SSL certificate for those services.

Model:

Browser -> SSL -> Load Balancer -> SSL -> Web App - Need SSL here -> Backend service

Backend service is a nodejs app using ClusterIp.

Any pointers on how to go about?

Thanks, Karthik

Hello,

One way to do this would be to generate a self-signed SSL certificate.

You can do that by following the instructions from step 2 from this tutorial here:

Hope that this helps!

Best,

Bobby
