What is a buildspec.yml file?

A buildspec.yml is a YAML file that tells CodeBuild what commands to run during each phase of the build. It must be in the root of your source code repository (or specified in the build project configuration). It defines install, pre_build, build, and post_build phases along with artifacts, cache, and environment settings.

Can I use multiple buildspec files in one repository?

Yes. You can specify a custom buildspec file path or name in the CodeBuild project configuration or in the CodePipeline action settings. This is useful for repositories with multiple build targets, like separate buildspecs for development and production builds.

About This Tool

The CodeBuild Buildspec Generator creates AWS CodeBuild buildspec.yml files through a guided form interface. The buildspec file defines your build phases (install, pre_build, build, post_build), environment variables, artifacts, caching, and reports configuration. This tool lets you select your runtime, specify commands for each phase, and configure advanced options like Docker layer caching and S3 artifact uploads, generating a properly formatted YAML file.

When to Use This Tool

•Generate a buildspec.yml for a Node.js or Python project with dependency installation, testing, and Docker image building phases.
•Create buildspecs with proper caching configuration for npm, pip, or Maven dependencies to speed up subsequent builds.
•Build a buildspec for a multi-stage pipeline that runs unit tests, builds artifacts, and pushes Docker images to ECR.
•Configure buildspec reports to publish test results and code coverage to CodeBuild's test reports feature.
