Overview

This repository contains the scripts to create a Docker image that can act as an Azure DevOps agent.
It also contains scripts to create an Azure Container Instance environment & Azure Container Registry.

The Azure Function project acts as an orchestrator to start and stop the ACI based on the information it can retrieve from Azure DevOps.
