Are you new to AWS CodeBuild and wondering how it fits into your CI/CD pipeline? You’re in the right place! In this post, we’ll walk through what CodeBuild is, how it works, and why it’s a powerful tool for modern developers.
📦 What is AWS CodeBuild?
AWS CodeBuild is a fully managed build service in the cloud, and a part of the AWS Developer Tools suite.
Why use CodeBuild?
✅ Serverless – No servers to provision or manage.
🔄 Scalable – Automatically scales to meet your build volume.
💰 Cost-effective – You pay only for the minutes your builds run.
🧪 CI/CD integration – Acts as a command line tool in your pipeline.
How does it work?
CodeBuild uses Docker containers to run build environments.
You can use:
- Prebuilt Docker images provided by AWS
- Your own Docker images from Docker Hub or Amazon ECR
Supported platforms: Ubuntu, Amazon Linux 2, and Windows Server Core
🛠️ What is a Buildspec?
A buildspec is a YAML file that tells CodeBuild how to run your build.
Key features:
It can be:
- Included in your source code repo (usually as buildspec.yml)
- Defined directly in the AWS Console
Contains instructions organized into phases:
- install
- pre_build
- build
- post_build
You can:
- Set runtime environments (in install phase)
- Define output artifacts
- Add environment variables as key-value pairs
- Integrate with Parameter Store and Secrets Manager
💡 Tip: Define environment variables in the project settings to reuse the same buildspec.yml across different environments or projects.
🧰 Managing Build Projects
Here’s what you can do with AWS CodeBuild:
- Add CodeBuild projects to your CI/CD pipelines
- Create standalone projects for one-off or reusable builds
- Schedule builds using AWS EventBridge or CloudWatch
🔒 Security in CodeBuild
AWS CodeBuild ensures your builds are secure by default:
- 🔐 Data-in-transit is encrypted with SSL and Signature Version 4
- 💾 Data-at-rest in Amazon S3 is encrypted with Customer Managed Keys (CMKs) via AWS KMS
- 🔑 Access is controlled using AWS IAM
- 🤖 Pipelines use IAM service roles to run CodeBuild projects securely
🎯 Final Thoughts
AWS CodeBuild is a powerful and flexible build tool, especially when used with other AWS Developer Tools like CodePipeline. Whether you're just getting started with CI/CD or looking to scale your build process, CodeBuild is worth exploring.
