Health Checks: Liveness & Readiness Probes
Configure liveness and readiness probes to ensure your applications are healthy and ready to serve traffic.
Keeping Apps Healthy
How does Kubernetes know if your application is truly working? It's not enough for a container to just be running; it needs to be healthy and ready to serve traffic.
Kubernetes uses special checks called probes to monitor your applications. These probes help ensure your users always experience a reliable service.
What are Liveness Probes?
A Liveness Probe checks if your application is still alive and responsive. If a liveness probe fails, Kubernetes assumes your container is unhealthy and will restart it.
Think of it like a heartbeat monitor: if the heart stops, a restart is needed! This helps recover from deadlocks or application crashes.
