What are Kubernetes pod health checks?

Kubernetes pod health checks are mechanisms to determine the health of a pod. They include liveness and readiness probes.

How do liveness and readiness probes differ?

Liveness probes check if a pod is running, while readiness probes determine if a pod is ready to accept traffic.

Can you give me an example of a liveness probe configuration?

Sure! A simple liveness probe can be configured using an HTTP GET request to a specific endpoint, like this:

livenessProbe:
  httpGet:
    path: /healthz
    port: 8080
  initialDelaySeconds: 30
  periodSeconds: 10

What happens if a pod fails the liveness probe?

If a pod fails the liveness probe, Kubernetes will automatically restart it to try to recover from the failure.
