Description: A Readiness Probe in Kubernetes is a mechanism that checks if a pod is ready to receive traffic. This check can involve HTTP requests, TCP connections, or executing commands within the container. The Readiness Probe is crucial for ensuring that only fully operational pods ready to handle requests are exposed to users. This helps prevent errors and enhances user experience by avoiding traffic directed to instances that have not completed initialization or are in an unstable state. Probes are configured in the pod specification file and can include parameters such as timeout, number of retries, and interval between checks. Proper implementation of readiness probes is essential in production environments where availability and reliability are critical. In summary, Readiness Probes are a key tool in managing the health of applications deployed on container orchestration platforms, ensuring that services remain operational and efficient.
