What are the best practices for Kubernetes pod probes?

Best practices for Kubernetes pod probes include using readiness and liveness probes effectively, setting appropriate timeouts, and ensuring your application can handle probe requests without performance degradation.

Can you explain the difference between readiness and liveness probes?

Sure! Readiness probes determine if a pod is ready to accept traffic, while liveness probes check if a pod is still running. If a liveness probe fails, Kubernetes will restart the pod.

How do I configure these probes in my deployment?

You can configure probes in your deployment YAML file under the spec section. For example, you can define livenessProbe and readinessProbe with parameters like httpGet, initialDelaySeconds, and timeoutSeconds.

What should I do if my probes are failing?

If your probes are failing, check the application logs for errors, ensure the probe endpoints are correct, and verify that your application is healthy and responsive.
