Configure Liveness, Readiness and Startup Probes
 This page shows how to configure liveness, readiness and startup probes for containers.
For more information about probes, see Liveness, Readiness and Startup Probes
The kubelet uses liveness probe...

What is the difference between health, liveness, readiness, and startup? This article does a great job at a full writeup description of how it works in kubernetes, here is my TLDR.

* health 200 OK - I'm still responding to requests
* health ERR - something happened and I cant respond to requests

* liveness 200 OK - I'm ready for more work
* liveness ERR - I'm still responding to requests, and i'm already working send requests to another pod, or scale up

## Z-pages

These probes are commonly deployed at `/healthz` and `/livez` endpoints.

Why the z?

z is a convention that comes from google for meta endpoints to reduce conflict with actual endpoints, and can be deployed to any application.
