Proposal for final CodePipeline Actions API shape #459

skinny85 · 2018-07-31T23:58:44Z

This PR contains what will (hopefully) be the final iteration of the way we structure our CodePipeline Actions.

The API shape is the following:

All Actions integrating with AWS services live in the service's package (so, the CodeCommit Action lives in the aws-codecommit package, the CodeBuild ones - in aws-codebuild, etc.).
There is a separate aws-codepipeline-api package that contains the Actions API, on which the service packages depend on (in order to prevent dependency cycles).
The API of Actions changed - you now provide a Construct as the parent, while the Stage is a required property in the props.

Sadly, there is no support for “re-exporting” symbols in jsii, which means we can’t vend aws-actions to all languages. What I suggest is providing pointers in the codepipeline README to all action types. This will be where people will naturally look for them.

What if we kept the aws-codepipeline-aws-actions module in other languages, but remove the re-exporting part? This way, it would leave it as only depending on the other Action modules, and in this way make it a little easier for customers to just import all of them in one go. Does that have enough value?

Also, any comments on the changed names of the Actions?

aws-actions feels convoluted and confusing... how about we start without, and see if it's needed?
No comments on the the action names - 👍

skinny85 · 2018-08-02T22:46:45Z

Thanks for the review @eladb . I've submitted a new version, removing the aws-codebuild-aws-actions module completely, and updating the ReadMe of the aws-codepipeline module.

If this looks right to you, feel free to merge this in.

Missed updating some outdated comments in the actions.ts file in the aws-codepipeline package in the previous revision, corrected now.

+The most popular Actions for external integrations


I wouldn't use the term "the most popular".
Also, the word "integration", which I know is used internally, is a bit confusing. I would just use something like "Pipeline actions for external services" and then, "Pipeline actions for AWS services"

Will change.

skinny85 · 2018-08-03T21:29:39Z

I had one more thought in favor of the aws-codepipeline-aws-actionsmodule (I'm not in love with the name either just to be clear, I'm open to suggestions on a better one) that I wanted your opinion on @eladb .

Currently, we face a question of where to put the external Actions (like GitHub source, Jenkins build, Jenkins test, etc.). Right now, they live in the codepipeline package, but that makes them "special", and different from the AWS Actions. Also, with 100% certainty I can say that not all of the external Actions available in the CodePipeline UI will be in that package (I don't imagine we will put the less popular ones, like Solano CI and Ghost Inspector UI Testing, for example, in there).

We could create a dedicated package for them, something like aws-codepipeline-external-actions (working name). In that case, it seems like having an aws-codepipeline-aws-actions module could be nice, for symmetry and discoverability.

We could even make aws-codepipeline-external-actions be just an empty package that depends on the particular integrations package (like aws-codepipeline-github, aws-codepipeline-jenkins, etc.), to make it more similar with AWS Actions.

I would love to know what's your opinion on this @eladb .

Thanks!

skinny85 · 2018-08-10T01:14:00Z

After our meeting, I've completely re-structured the API according to what we agreed to. I've updated the PR description accordingly.

Sorry for the gigantic CR, but I'd rather rip the band-aid off. Also, it's 95% just moving stuff around (and the necessary changes resulting from that moving around, like different imports because of changing package memberships, etc.).

We cannot. In the S3 Action, we pass pipelineRole as a parameter into Bucket#grantRead.

Why do actions need access to the stage name?

It's used in 2 places right now:

The onStateChange method in Action class (the root of the Actions hierarchy).

The CloudFormationAction abstract class (uses it to name the output artifact).

+export interface AbstractActionProps {


I think this might be redundant. If you require this prop by the abstract base class it will force everyone to include it in their props. It also has the benefit of have “stage” appear in docs in every actio props. Otherwise, people will have to traverse to the hierarchy.

We can always add this abstraction in the future if we see there’s More to it than just “stage” but this feels like taking it one step too far

The reason I did it this way is otherwise, we will copy & paste the same documentation for the stage property into 8+ different places. Granted, I didn't write any JsDocs for this property either, but that's a separate discussion ;p.

Not sure that's a good enough reason... It's not such a complicated description...

I actually have a second candidate property for this interface in mind: runOrder.

Does having 2 properties here make this interface valuable enough, in your opinion?

Yes. It will be moved as part of #492 once this is shipped (or I'll rebase #492 on top of this, depending on how much back-and-forth we'll have).

I have a backlog item in our internal issue tracker for each of these - trust me, I will not forget them :).

This looks like what I proposed earlier instead of another interface. I would allude to the bucket in the name of the method (because stage.grantReadWrite) is weird

Like I proposed above: does stage.grantPipelineBucketReadWrite sound good to you?

Yes, if you prefer (I hate long names). Since this method is part of the pipeline's stage, I think "pipeline" is not really needed by the context, but that's fine :-)

No idea why the build is failing... Stage definitely implements grantPipelineBucketReadWriteTo correctly in TypeScript... could it be because the type in the declaration of grantPipelineBucketReadWriteTo is optional (identity?: iam.IPrincipal)?

Regarding the build break. Seems like a jsii bug, but we need to dive deeper. You should be able to run jsii-pacmak --recurse from your package and it will generate and build the java version of your module:

lerna exec jsii-pacmak --scope="@aws-cdk/aws-codepipeline-api" -- --recurse --no-clean -v

--no-clean will preserve the sources (you should see a path somewhere in the output), which will allow you to investigate a bit further.

Let us know what you find out...

@skinny85 you discovered a bug in jsii (aws/jsii#175). Workaround for now is to modify the signature of grantPipelineBucketReadWriteTo such that identity is required and not optional. Open an issue to track fixing this one the jsii bug is fixed please.

BREAKING CHANGE: 1. Introduce a new aws-codepipeline-api package, and move the Actions API there. 2. Move the service-specific Actions back into their service packages.

…instead of parent. BREAKING CHANGE: this commit changes the way we pass a Pipeline to a newly created Stage. Instead of passing it as a parent, in the first argument of the constructor, we now pass it through a separate props object, in the pipeline property. This is in order to make Stage more consistent with other Constructs, and with the changes made to the Actions API in aws#459.
