Configure Kubernetes health checks by defining specific HTTP or TCP endpoints for readiness, liveness, and startup probes. This signals your application's operational status to the Kubernetes control plane for robust lifecycle management.

Readiness probes signal when an application is ready to serve traffic, liveness probes determine if an application is running and needs restarting, and startup probes monitor initial initialization to delay other checks until fully booted.

Add /healthz/ready, /healthz/live, and /healthz/startup endpoints to your application configuration to establish HTTP health check paths. This ensures Kubernetes effectively manages your containerized application lifecycle.

You need startup probes when deploying applications with slow initialization processes. They monitor initial startup and delay readiness and liveness checks until the application is fully initialized, preventing premature restarts.

Yes, you can define either specific HTTP or TCP endpoints for Kubernetes liveness probes. Configuring TCP endpoints allows the control plane to check operational status when HTTP paths are not available.

Kubernetes restarts containers prematurely when liveness probes fail before initialization completes. Setting up startup probes delays liveness and readiness checks until the application is fully initialized, preventing unwanted restarts.
