A Simple Coffee Site

I recently deployed a simple Next.js application to AWS and built an automated CI/CD pipeline:

GitHub → GitHub Actions → Docker → ECR → ECS Fargate → Application Load Balancer → Live App

The pipeline now automatically handles:

• Linting and building the application

• Docker image creation and tagging

• Pushing images to Amazon ECR

• Creating new ECS task definition revisions

• Deploying updates to ECS

• Waiting for ALB health checks before completing the deployment

The process came with a few challenges — including IAM AccessDeniedException errors, iam:PassRole, ECS permissions, security group configuration, ALB connectivity, and making sure the latest image was actually running.

After troubleshooting those issues, a git push can now take a change from code all the way to a running container on AWS.
