AWS CodePipeline-Driven CodeBuild Builds

Overview

CodeBuild can be integrated with CodePipeline so CodeBuild build projects can be used at the build stage of a CodePipeline release pipeline, backing a CodePipeline build action.

Integration

The integration consists in the following steps:

Create the CodeBuild Build Project

The CodeBuild build project can be created automatically as part of an CloudFormation stack, most likely the same one that creates other resources required by the CodePipeline, and the pipeline itself. A typical CloudFormation specification is shown below. Aside typical configuration details such as image type and build environment size, the CloudFormation AWS::CodeBuild::Project section can be used to declare stack-specific and project-specific configuration information that will be injected as environment variables into the build container.
