Example of a simple Lambda function (with serverless framework) that triggers wercker build!

npm i -g serverless

Configure via secrets.yml

wercker: token
applicationId: get it from fetchApplications
username: your_user

Listing all applications:

serverless invoke local -f fetchApplications

To test it locally:

serverless invoke local -f triggerBuild

To deploy it:

serverless deploy

It will trigger a build every 6 hours by default.
