Kubernetes health checks are essential for maintaining the reliability of distributed microservices-based systems, as they help detect unhealthy applications, reroute requests, and restore broken components. These health checks use probes—such as Liveness, Readiness, and Startup probes—to monitor the state of containers and determine when they are ready to accept traffic or need restarting. Probes can be configured using HTTP(S), TCP, command, and gRPC protocols, each suited for different types of applications and services. Proper implementation of health checks can significantly enhance troubleshooting efficiency by providing insights into application readiness and performance issues. Tools like Komodor's Continuous Kubernetes Reliability Platform further aid in managing Kubernetes environments by offering features like health monitoring, access governance, drift detection, and cost optimization, enabling teams to focus more on innovation rather than operational complexities.
