Azure DevOps Agents on Azure Container Instances (ACI)

This post introduces a solution for running Azure DevOps agents on Windows Server Core containers hosted on Azure Container Instances (ACI). This approach offers scalability, customization (installing specific tools like Terraform, json2hcl, and PowerShell modules), and enhanced security (no public IPs, no exposed ports, no interactive logons) compared to Microsoft-hosted agents or traditional IaaS VMs. It details three PowerShell scripts for initialization, installation, and removal, and outlines prerequisites and lifecycle management.
