Why Kubernetes Health Checks Are a False Sense of Security

Episode 30 of DevOps Daily with Fexingo: Lucas and Luna dig into why standard Kubernetes liveness and readiness probes often give teams a false sense of security. They walk through a real-world case where a service passed health checks but crashed under load because probes only tested a single endpoint. They break down the difference between basic TCP probes, HTTP probes, and deep dependency-aware probes, and explain why teams need to instrument startup probes and custom readiness gates. They also cover how Inc's 2025 postmortem on a multi-hour payment outage traced back to a stale readiness probe. By the end, listeners understand why a health check is only as good as the dependencies it actually tests. #Kubernetes #HealthChecks #LivenessProbes #ReadinessProbes #SiteReliabilityEngineering #CloudNative #DevOps #IncidentResponse #PodLifecycle #StartupProbes #DependencyManagement #ContainerOrchestration #TechOps #Observability #ProductionDebugging #ReliabilityEngineering #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
