CodePipeline inside cdk-pipelines, How?

[nitsujri]

I'm exploring how to do CI/CD using cdk-pipelines, but while the setup part works, I don't understand the control part. All the examples are really simple inline code Lambda Functions.

How do I "release a change" of a codepipeline.Pipeline inside a cdk_pipelines?

const cdk_pipeline = new pipelines.CodePipeline(...)
cdk_pipeline.addStage(new BuildImageTestStage(...))

// build-image-test-stage.ts
new BuildImageTestStack(...)

// build-image-test-stack.ts
const pipeline = new codepipeline.Pipeline(...)
pipeline.addStage(...CodeStarConnectionsSourceAction...)
pipeline.addStage(...CodeBuildAction...)

It sets up the pipeline just fine, but it doesn't fire off the actual codepipeline itself.

Options that I see:

• codepipeline.Pipelines(triggerOnPush: true) - doesn't work because I want the cloud formation to run first THEN build+test. Trigger on push effectively runs parallel.
• Completely separate setup from code deployment by using codepipeline_actions.CloudFormationCreateUpdateStackAction

Unsure option:

• cdk_pipeline.addStage(..., { post: [] }) - CDK Pipeline post to trigger a code deploy, but I'm unsure on how to "wait" for it to finish.

Separately, I wish cdk-pipelines were named differently than codepipeline. It's just so hard to search.
