Configuring an Ingress for Custom Header Transmission to Upstream Server

[sajith-madhusanka]

What do you want to happen?

My requirement is to configure an ingress to send the client certificate to the upstream server in a custom HTTP header. I have followed the instructions in [1] to send a custom header to the upstream server using the following configuration.

apiVersion: v1
data:
  X-CLIENT-CERTIFICATE: $ssl_client_escaped_cert
kind: ConfigMap
metadata:
  name: custom-headers
  namespace: ingress-nginx

Since this applies globally to all the ingresses deployed in my deployment, I need a way to configure a specific ingress to send custom headers to the upstream server.
