Describe the solution you'd like

We operate PGWatch in a Kubernetes cluster and need to add standard endpoints for liveness and readiness probes to PGWatch.

Thanks

Where one can fine those standards described?

For example, here: https://cloud.google.com/blog/products/containers-kubernetes/kubernetes-best-practices-setting-up-health-checks-with-readiness-and-liveness-probes. We also have this requirement as part of our internal requirements for monitoring and operating applications in our internal K8S cluster.

So it's basically up to the developer how to name endpoint and what status code to return, right? Because probe can be configured, right?

[tvecera]

Yes, these endpoints usually also return "ok" or "error" in the response body. They are typically at the /health or /healthz endpoint, but it doesn't matter.
