I'm looking for solution how to encrypt traffic between Traefik frontend to kubernetes Ingress resource serving multiple application. The examples on internet, e.g. [1], show how to enable TLS support in Traefik or even use Let's Encrypt for Traefik and Ingress controller [2]. The problem is that all of them pass HTTPs request from frontend to HTTP backend. What I'm looking for is end-to-end encryption between frontend and backends.

I enabled TLS in Traefik as shown in [1], I enabled TLS in Ingress as shown [3], but still all traffic goes from HTTPs to HTTP. And, I don't know who is responsible for this decision (where it should be configured) the Traefik or Ingress.

Any suggestions?
