Achieving Zero Downtime Deployment with Kubernetes Rolling Updates
Update a running containerized application without downtime using rolling updates.
1. Why We Need This Use Case:
In modern software development, continuous delivery and deployment are critical to ensuring rapid feature releases, bug fixes, and performance improvements. However, updating an application with minimal or no downtime remains a significant challenge, especially in production environments where service availability is crucial. Kubernetes provides a built-in solution to this problem through Deployments and rolling updates. By leveraging rolling updates, applications can be updated without disrupting end users, ensuring a smooth transition to new versions.
2. When We Need This Use Case:
When deploying a new version of an application without disrupting ongoing operations.
When applying security patches or bug fixes to containerized applications.
In production environments where zero downtime is a requirement.
When using microservices that need frequent updates.
To maintain high availability in customer-facing applications.
