What are the best practices for Kubernetes probes?

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

Can you explain the difference between readiness and liveness probes?

Sure! Liveness probes check if your application is running, while readiness probes determine if it's ready to handle traffic. If a liveness probe fails, Kubernetes will restart the pod; if a readiness probe fails, the pod will be removed from the service endpoints.

What should I consider when setting the timeout for probes?

When setting timeouts, consider the expected response time of your application, network latency, and the potential for temporary issues. A good practice is to set a timeout that allows for normal fluctuations in response time.

Are there any common mistakes to avoid with probes?

Yes, common mistakes include setting timeouts too short, not using both readiness and liveness probes, and failing to test probes thoroughly in different scenarios.
