What happened?
When the grid isn't ready the healthcheck shouldn't return a 200 OK status code.
I think the correct status code would be 503.

When the grid would return a proper status code - health checks would make a real sense, which could lead to a pod restart.
How can we reproduce the issue?
Start a hub in kubernetes and see the health check statuscode in your browser. It's always "OK".
