Pipeline add CodeBuildAction

[HannesOberreiter]

Hi,

I try to reference an existing CodeBuild project and add it to my pipeline as separate stage. But currently stuck how to connect it as I can only add steps.

const testPipeline = pipeline.addWave('Test');
const testProject = PipelineProject.fromProjectArn(
        this,
        'e2e',
        'arn:aws:codebuild:eu-central-1:XXXX:project/buildspec-e2e-local-cache'
);
const e2eAction = new CodeBuildAction({
        actionName: 'e2e',
        project: testProject,
        input: new Artifact(),
        outputs: [new Artifact()],
});
testPipeline.addPost(e2eAction); // This wont work as the action is not a stage

Any help is appreciated!

Cheers
Hannes

Hi @HannesOberreiter , To add an existing CodeBuild project to your pipeline as a separate stage, you can use the following steps:

1. Create a new stage in your pipeline.
2. In the stage, add a CodeBuild action.
3. In the CodeBuild action, specify the name of your existing CodeBuild project.
4. Specify the input and output artifacts for the CodeBuild action.
5. Save your changes and deploy your pipeline.

const testPipeline = pipeline.addWave('Test');

// Create a new stage in your pipeline.
const e2eStage = testPipeline.addStage('E2E');

// Add a CodeBuild action to the stage.
const e2eAction = new CodeBuildAction({
  actionName: 'e2e',
  project: PipelineProject.fromProjectArn(
    this,
    'e2e',
    'arn:aws:codebuild:eu-central-1:XXXX:project/buildspec-e2e-local-cache'
  ),
  input: new Artifact(),
  outputs: [new Artifact()],
});

// Add the CodeBuild action to the stage.
e2eStage.addAction(e2eAction);

// Save your changes and deploy your pipeline.

Let me know if this helps!

Hi @khushail,

thank you very much for your quick response! I did not mention it but I use cdk v2 and I believe your solution is from v1?

Some of your steps wont work for v2 or maybe I miss something.

This wont work as addStage expects an actual cdk.Stage:
const e2eStage = testPipeline.addStage('E2E');

I also tried with a dummy stage as workaround but then I found out that the method addAction is not available in v2?
e2eStage.addAction(e2eAction);

Cheers
Hannes

@HannesOberreiter coming here from the other thread. I think this snippet fell into the pitfall I described here where there are two similar libraries with the same name for stuff. See my comment here, I linked to the documentation where we describe how to add any arbitrary action to a stage when using our high level pipelines library
