Kubernetes Liveness and Readiness Probes for Nginx Proxy

Hello,

I am using nginx as a reverse proxy in a Kubernetes Cluster where I have multiple services terminating TLS and being routed to the appropriate servers. The one question I have is how best to setup Liveness and Readiness probes on the Kubernetes side, so that the nginx pod is not dependent on a single service.

Is there a best practice? Should I setup a faux service just to facilitate the checks?

Any help or suggestions is greatly appreciated.
Thanks
Ray
