Re-encrypt example

Hi,
I am looking for a solution. My application running on k8s is TLS enabled (self signed certificate and listen at 8200), now I want that when the TLS traffic coming from client gets terminated at Traefik ingress level and then Traefik ingress will re-encrypt the traffic using my application certificate (self signed certificate) before forwarding it to my application.
What options I have available ?

Thanks in advance
