Maintaining high availability and minimizing downtime during deployments is critical in modern software development.
This article walks you through designing a Blue/Green deployment using Minikube, Docker, and Kubernetes.
Blue/Green deployments effectively switch traffic between two identical environments, allowing seamless updates.
What Is a Blue/Green Deployment?
A Blue/Green deployment involves running two production environments: Blue (the current version) and Green (the updated version). Only one environment is live at any time, and traffic is routed.
Updates are deployed to the inactive environment, and after testing, traffic is switched. This ensures zero downtime and simplifies rollback if issues arise.
Project Overview
• Blue Environment: Displays a blue background.
• Green Environment: Displays a green background.
• Traffic Switching: Use Kubernetes to toggle between environments.
Prerequisites
1. Minikube
