Validating the health of our https://kubernetes.io/docs/concepts/workloads/ — applications running on Kubernetes — is crucial to their success. To manage workload health, we rely on telemetry information and diagnostics, which are often captured via system and application components and then sent to a monitoring tool.

Before we explore how to use Kubernetes probes efficiently, we must familiarize ourselves with the three kinds of Kubernetes probes: startup, readiness and liveness.

In this article, we explored the important role of health checks for validating containers and how Kubernetes probes enable us to perform these checks.

The more accurately we can tune our probe parameters, the better our probe checks, autoscaling capabilities and overall Kubernetes application performance will be.
