Requirements

To use the code in this repository, you will need the following applications:

• HashiCorp Terraform 0.14.4 (or later)
• HashiCorp Packer 1.6.6 (or later)
• Azure CLI az 2.0.0 (or later)

Additionally, you will need a GitHub Personal Access Token.

Workflows

The code in this repository is split out into a handful of distinct flows, each in their own directory:

• terraform/azure contains code for Terraform to set up an Azure Resource Group and generate a Packer variables definition file
• packer contains code for Packer to build a (very!) basic image for an Azure Linux Virtual Machine
• terraform/azure-compute contains code for Terraform to start a Linux Virtual Machine with the Packer image
• terraform/github contains code for Terraform to set up a GitHub Organization's memberships and repository
• .github/workflows contains GitHub Actions to ensure code quality for Packer and Terraform projects

Each directory contains its own README.md with information relevant to the workflow.

Additional Reading

While the authors of this repository take care to explain all workflows with the amount of detail required to execute them, the information here should not be considered exhaustive.

This section is a collection of links that will help you make the most of today's session.
