CodeBuild & CodeArtifact

• CodeBuild = Automates code compilation and testing.
• CodeArtifact = Stores and manages software packages.

CodeBuild

CodeBuild

AWS’s CI/CD build service—it takes your source code, runs build commands, and produces artifacts

• Managed execution environment
• Automates code compilation and testing

• What it does: Compiles source code, runs tests, and generates deployable packages.

  • can build Docker images from source, storing artifacts in ECR or S3, with no server management

• Fully managed: No need to maintain build servers.

• Pay-as-you-go: Charged based on build minutes.

• Example use case: You push code to CodeCommit → CodeBuild runs npm build or make → It outputs an artifact (like a ZIP file) for deployment.

• Configure Environment

  • Choose code source (github repo, etc)
  • Execution environment (OS, base software)
  • Extra settings (timeouts, environment variables)

• Configure Execution steps

  • Create a buildspec file (contains the details of what should happen in this environment)
    • ex. download packages, start tests, build code, etc
    • can execute any kind of commands in order to test & build ur app correctly
    • official docs
  • Define build output (“artifacts”) details if any (ex. where it should be stored in S3)
  • Run manually or based on triggers

CodeArtifact

CodeArtifact

AWS’s managed package repository (like npm registry, PyPI, Maven, etc.)

• lets you store, share, and retrieve software packages securely within your AWS environment

• Two main things
  • A private repository for your team’s internal packages (so only authorized users can access them).
  • A proxy for public repositories like NPM, PyPI, Maven Central, etc. (so you don’t have to download public packages separately).
• Private & secure: IAM-based access control.
• Example use case: Instead of publishing your team’s packages to npmjs.com, you push them to CodeArtifact for internal use.
