Health Probes enable Kubernetes to automatically detect and recover from application failures, ensuring high availability. Understanding Health Probes The Problem Without Probes: Crashed applications continue receiving traffic Deadlocked processes never recover Slow-starting apps receive traffic too early Failed containers remain in “Running” state The Solution: Health probes provide automated health monitoring and recovery: Automatic restart of failed containers Traffic routing only to healthy pods Graceful startup for slow applications Self-healing without manual intervention Types of Probes - Complete Comparison Probe Type Purpose Action on Failure When to Use Liveness Is container alive?
