Configure Traefik to Pass Health Checks on GCP

Google Cloud GCP Will NOT forward to Ingress that does not pass health checks. Could anyone share how exactly to configure Traefik Ingress to pass health checks? I think it needs to return a 200 on /health or something like that. But what would exact configuration look like? I am starting traefik using arguments rather than toml file. Thanks. 304 not accepted. Must be 200 I think. If I use the arg list what do I need to do to enable health checks?

UPDATE LATEST: CONFIG AND LOGS:

UPDATE: Here is my deployment. I think this correct but looking at the logs I am getting:

- - [29/Jun/2019:16:21:44 +0000] "GET /health HTTP/1.1" 404 19 "-" "kube-probe/1.13+" 4 "backend not found" "/health" 0ms

How do I setup to return the 200?

UPDATE: there is a ping setting but how to map this to health

# Ping definition
[ping]
  # Name of the related entry point
  #
  # Optional
  # Default: "traefik"
  #
  entryPoint = "traefik"

How to I enable /health which is where health check is done?
