Here's my thought on 💭 Configure Liveness, Readiness and Startup Probes | Kubernetes

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


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.
