Description: Graceful update in container orchestration systems is a process designed to manage the transition of tasks in a container cluster in an orderly and efficient manner. This approach allows existing tasks to finish correctly before new instances are started, thereby minimizing downtime and ensuring that services remain available during the update process. The main feature of graceful update is its ability to handle the termination of active tasks, meaning that user connections and ongoing operations are not abruptly interrupted. This is especially crucial in production environments where availability and service continuity are essential. Additionally, this process allows system administrators to implement changes in configuration or container images without affecting the end-user experience. In summary, graceful update is a technique that enhances the resilience and stability of applications deployed in container orchestration environments, allowing for smoother management of updates and reducing the risk of failures during the deployment of new versions.
