Keeping Applications Healthy with Liveness Probes
Understand how Kubernetes liveness probes work to keep applications healthy by periodically checking their status. Learn to configure both HTTP and custom command probes to detect unhealthy states and automatically restart failing pods, ensuring stable deployments.

livenessProbe and readinessProbe
Sometimes applications will enter an unhealthy state after they have been running for a while. Our buggy applications could, for example, start failing just after the 1000th request instead of the third, so our readinessProbe would happily pass. But after some time, the app would start returning a 500. To deal with this issue, Kubernetes also provides a livenessProbe.
A pod that crashes will already be restarted, as we have seen. But a ...
