CodePipeline samples for CodeBuild

AWS CodePipeline integration with CodeBuild and batch builds

AWS CodeBuild now supports batch builds. This sample demonstrates how to use AWS CodePipeline to create a build project that uses batch builds.

You can use a JSON-formatted file that defines the structure of your pipeline, and then use it with the AWS CLI to create the pipeline. For more information, see AWS CodePipeline Pipeline structure reference in the AWS CodePipeline User Guide.

Batch build with individual artifacts

Use the following JSON file as an example of a pipeline structure that creates a batch build with separate artifacts. To enable batch builds in CodePipeline, set the BatchEnabled parameter of the configuration object to true.

              "BatchEnabled": "true"
            },

    },

    "version": 1
  }
}

The following is an example of a CodeBuild buildspec file that will work with this pipeline configuration.

version: 0.2
batch:
  build-list:
    - identifier: build1
      env:
        compute-type: BUILD_GENERAL1_SMALL
    - identifier: build2
      env:
        compute-type: BUILD_GENERAL1_MEDIUM

phases:
  build:
    commands:
      - echo 'file' > output_file

artifacts:
  files:
    - output_file
  secondary-artifacts:
    artifact1:
      files:
        - output_file
    artifact2:
      files:
        - output_file

The names of the output artifacts specified in the pipeline's JSON file must match the identifier of the builds and artifacts defined in your buildspec file. The syntax is buildIdentifier for the primary artifacts, and buildIdentifier_artifactIdentifier for the secondary artifacts.

For example, for output artifact name build1, CodeBuild will upload the primary artifact of build1 to the location of build1. For output name build1_artifact1, CodeBuild will upload the secondary artifact artifact1 of build1 to the location of build1_artifact1, and so on. If only one output location is specified, the name should be buildIdentifier only.

After you create the JSON file, you can create your pipeline. Use the AWS CLI to run the create-pipeline command and pass the file to the --cli-input-json parameter. For more information, see Create a pipeline (CLI) in the AWS CodePipeline User Guide.

Batch build with combined artifacts

Use the following JSON file as an example of a pipeline structure that creates a batch build with combined artifacts. To enable batch builds in CodePipeline, set the BatchEnabled parameter of the configuration object to true. To combine the build artifacts into the same location, set the CombineArtifacts parameter of the configuration object to true.

The following is an example of a CodeBuild buildspec file that will work with this pipeline configuration.

version: 0.2
batch:
  build-list:
    - identifier: build1
      env:
        compute-type: BUILD_GENERAL1_SMALL
    - identifier: build2
      env:
        compute-type: BUILD_GENERAL1_MEDIUM

phases:
  build:
    commands:
      - echo 'file' > output_file

artifacts:
  files:
    - output_file

If combined artifacts is enabled for the batch build, there is only one output allowed. CodeBuild will combine the primary artifacts of all the builds into one single ZIP file.

After you create the JSON file, you can create your pipeline. Use the AWS CLI to run the create-pipeline command and pass the file to the --cli-input-json parameter. For more information, see Create a pipeline (CLI) in the AWS CodePipeline User Guide.

AWS CodePipeline integration with CodeBuild and multiple input sources and output artifacts sample

An AWS CodeBuild project can take more than one input source. It can also create more than one output artifact. This sample demonstrates how to use AWS CodePipeline to create a build project that uses multiple input sources to create multiple output artifacts. For more information, see Multiple input sources and output artifacts sample.

You can use a JSON-formatted file that defines the structure of your pipeline, and then use it with the AWS CLI to create the pipeline. Use the following JSON file as an example of a pipeline structure that creates a build with more than one input source and more than one output artifact. Later in this sample you see how this file specifies the multiple inputs and outputs. For more information, see CodePipeline pipeline structure reference in the AWS CodePipeline User Guide.

In this JSON file:

  • One of your input sources must be designated the PrimarySource. This source is the directory where CodeBuild looks for and runs your buildspec file. The keyword PrimarySource is used to specify the primary source in the configuration section of the CodeBuild stage in the JSON file.

  • Each input source is installed in its own directory. This directory is stored in the built-in environment variable $CODEBUILD_SRC_DIR for the primary source and $CODEBUILD_SRC_DIR_yourInputArtifactName for all other sources. For the pipeline in this sample, the two input source directories are $CODEBUILD_SRC_DIR and $CODEBUILD_SRC_DIR_source2. For more information, see Environment variables in build environments.

  • The names of the output artifacts specified in the pipeline's JSON file must match the names of the secondary artifacts defined in your buildspec file. This pipeline uses the following buildspec file. For more information, see Buildspec syntax. 

    version: 0.2

phases:
  build:
    commands:
      - touch source1_file
      - cd $CODEBUILD_SRC_DIR_source2
      - touch source2_file

    artifact2:
      base-directory: $CODEBUILD_SRC_DIR_source2
      files:
        - source2_file

After you create the JSON file, you can create your pipeline. Use the AWS CLI to run the create-pipeline command and pass the file to the --cli-input-json parameter. For more information, see Create a pipeline (CLI) in the AWS CodePipeline User Guide.
