Kubernetes nginx ingress ssl redirect behind SSL termination LB

ingress.yaml

annotations:
  # Since the SSL term happens at the LB level, nginx will always receive HTTP traffic, which will always cause 'force-ssl-redirect' to loop and the browser to get a 'too many redirects' error.
  # What we need to check in order to remedy this is which protocol the LB receives traffic in, HTTP or HTTPS, we do this by checking the header 'X-Forwarded-Proto', if it's HTTP, we redirect the client to the current URL ($host$request_uri), but with an added 'https://' prefix
  nginx.ingress.kubernetes.io/configuration-snippet: |
          if ($http_x_forwarded_proto = 'http'){
            return 301 https://$host$request_uri;
          }
