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 from 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 in the "EnvironmentVariables" section. This configuration will be injected as environment variables into the build container.

This configuration information can be inferred from the context, as is the case in Fn::ImportValue: !Sub '${AWS::Region}-BuildBucket' or ${ECRRepository}, or simply declared as parameters in the "Parameters" section of the template.

Passing Configuration from CodePipeline to Build

Use the EnvironmentVariables section of the CodeBuild build project declaration.

Artifacts

Input Artifacts

CodeBuild action provider looks for ZIPped sources into the S3 bucket subdirectory corresponding to the "OutputArtifacts.Name" configuration value of the source action. The subdirectory is created into a directory with the same name as the pipeline physical ID. The locations can be retrieved from the build project's build information:

Output Artifacts

CodeBuild places output files, as defined by the buildspec "artifacts.files" section, into the S3 bucket subdirectory corresponding to the "OutputArtifacts.Name" configuration value of the build action. The subdirectory is created into a directory with the same name as the pipeline physical ID.
