A proof of concept exploring monorepo builds in CodeBuild / CodeDeploy from a GitHub repository. This repository builds off the ideas described in this blog post, but implements them in CloudFormation.

Instructions

The infra/create-pipeline.sh creates the pipeline (for the first time). To create the pipeline, execute the following:

shell$ cd infra && ./create-pipeline.sh <a github personal access token>

The infra/update-pipeline.sh updates the existing stack for the pipeline.

Projects

This monorepo contains four "packages":

• foo and bar, two libraries
• main1 and main2, two main programs that each depend on foo and bar

The pipeline is setup for main1 and only triggers when there are updates to files under packages/(foo|bar|main1). Changes to main2 (alone) does not trigger the pipeline.

The pipeline currently just listens to GitHub PUSH events on master, so builds are only triggered when pushing to master.
