CI/CD with CodeBuild & CodePipeline

CI/CD Pipeline with AWS CodeBuild & CodePipeline

This guideline describes how to implement a production-ready CI/CD pipeline with AWS CodePipeline and CodeBuild using GitLab as SCM. When a new Release is created in the GitLab repository, CodePipeline is triggered, CodeBuild runs the frontend and backend projects using the existing frontend-buildspec.yml and backend-buildspec.yml, and then CodePipeline deploys to ECS.

What you’ll do

• 5.3.1 – Configure CodeBuild projects (frontend/backend) and trigger on GitLab Release
• 5.3.2 – Design CodePipeline for ECS deploy and integrate post-build artifacts

Prerequisites

• An IAM user/role with permissions for CodeBuild, CodePipeline, S3, ECR (if needed for GitLab token), and IAM pass role.
• An S3 bucket for pipeline artifacts (will be created by CodePipeline wizard or you can pre-create).
• ECR repository created.
