If you would like to do a quick POC Deploy of ARO, navigate to the CLI Deployment folder and review the instructions to deploy.
The goal with this repo is to show an example of how to deploy a private, secure ARO and force-tunnel traffic through Azure Firewall in the Hub VNET. You can fork this repo and add/customize as needed.
Under the hub-spoke-deployment directory you will find the guide to deploying the architecture.
