CodeBuild

💡 Definition

AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy.

🔑 Key Concepts

• Build Service: Compiles code and runs unit tests.
• Serverless: No build servers to manage. Scales automatically to meet peak build requests.
• Artifacts: Produces build artifacts (e.g., WAR files, ZIP files, Docker images) stored in S3.
• Buildspec: Uses a buildspec.yml file to define build commands and settings.

⚙️ How it Works

1. Source: Connects to CodeCommit, S3, or GitHub.
2. Build: Provision a temporary container, run the commands in buildspec.yml.
3. Output: Upload the resulting artifacts to an S3 bucket.

🎯 Use Cases

• Continuous Integration (CI): Running tests automatically whenever code is pushed.
• Compiling Code: Turning source code into executable applications.
• Docker Images: Building and pushing Docker images to Amazon ECR.

💰 Pricing Model

• Build Minutes: Charged per minute based on the compute instance type used for the build.

📝 Exam Tips (CLF-C02)

• "Compiles source code, runs tests, produces software packages".
• Serverless build service.
• Uses buildspec.yml.
