CI/CD How To 🧙

This tutorial assumes you have access to the Google Cloud Platform. While GCP is used for basic infrastructure requirements, the lessons learned in this tutorial can be applied to other platforms.

It's not a requirement. But reading through this tutorial will be easier and available offline utilizing vmd. It requires node.js installed which you can do with $ brew install node and then $ npm install -g vmd. Then in the root of the project $ cd ~/<WORK_DIR>/autoapp/ && vmd.
