A Github app that posts build logs from failed CircleCI jobs to Pull Requests.

For each pull request event, a webhook is sent to API Gateway, the request is authorized and ultimately an AWS Step Function is started. The step function runs very simple logic with Lambda functions and uses step function features to run this as cheap as possible.

• This currently uses two versions of the CircleCI API (v1.1 and the beta 2.0 API) so, this is likely to change and is as reliable as these API's
• This polls CircleCI APIs and definetly isn't perfect as is, I didn't event think this would be too possible based on the limited CircleCI API but, this is the MVP
• A much simpler approach would be to curl some endpoint inside your CircleCI build on failures (it's possible to configure a job to run on failures of other jobs) but, from a user experience I didn't want to have users modify their CircleCI configuration to work
• This code is rough! But, this is my first opensource golang project, I a still learning for sure.

• Improvements to reduce the amount of API calls to CircleCI
• Improvements on the backoff logic to wait for a build to finish
• A Terraform deployment guide
• A least privledge IAM policy to deploy this application
