This project contains Python source code and supporting files for a serverless application that you can deploy with the SAM CLI and that uses CodeDeploy and Lambda traffic shifting for deployment. This is a demo for my immutable infrastructure talk.
Placebo allows you to mock boto3 calls that look just like normal calls but actually have no effect at all. It does this by allowing you to record a set of calls and save them to a data file and then replay those calls later (e.g. in a unit test) without ever hitting the AWS endpoints.
