Probes are Kubernetes’ secret weapon for maintaining healthy, resilient applications in production. These diagnostic tools act as your application’s health monitoring system, regularly checking if your containers are alive, ready to serve traffic, and functioning as expected. By implementing three key probes types – liveness, readiness, and startup probes – you can create sophisticated health check mechanisms that prevent downtime and ensure smooth service delivery. Think of probes as your application’s vital signs monitor. Just as a doctor checks a patient’s pulse, temperature, and blood pressure, Kubernetes uses probe to monitor your containers’ health status. These checks can be as…
