About This Architecture

GitHub Actions CI/CD pipeline orchestrates automated builds, tests, and blue-green deployments to AWS ECS across multiple availability zones. Code pushes trigger GitHub Actions workflows that build Docker images, run tests, push to Amazon ECR, and invoke AWS CodeDeploy for zero-downtime deployments. The Application Load Balancer routes traffic between blue (live) and green (standby) ECS task groups, with CloudWatch health checks enabling instant rollback on deployment failures. This architecture eliminates downtime during updates while maintaining high availability across AZ-1 and AZ-2 in a VPC with isolated public and private subnets.

How do I set up a GitHub Actions CI/CD pipeline with blue-green deployments to AWS ECS?

This diagram shows a complete GitHub Actions workflow that triggers on code push, builds and tests Docker images, pushes to Amazon ECR, and uses AWS CodeDeploy to orchestrate blue-green deployments across ECS task groups. The Application Load Balancer switches traffic between live (blue) and standby (green) environments, while CloudWatch health checks enable automatic rollback if the new deploymen
