Self-Hosted VMSS Agents

Project Background

Azure DevOps pipelines using Microsoft-hosted agents are unavailable in Azure China, requiring organizations to deploy self-hosted agents instead.

This project delivers a Terraform-based solution for deploying self-hosted Azure DevOps agents through Virtual Machine Scale Sets (VMSS) in Azure China. The implementation provides:

• Scalable agent infrastructure to meet dynamic CI/CD demands
• Cost optimization through efficient resource utilization
• Automated deployment following infrastructure-as-code principles

Resources Created

The following resources are provisioned by this project:

• Virtual Machine Scale Set (VMSS): Hosts the self-hosted agents and ensures scalability.
• Azure DevOps Agent Configuration: Configures the agents to connect to your Azure DevOps organization.
• Virtual Network (VNet): Provides network isolation and connectivity for the VMSS.
• Subnets: Segments the VNet for better organization and security.
• Key Vault: Manages secrets and credentials securely.
• Storage Account: Stores logs and diagnostic data for the VMSS.

Module Directory

The project is divided into the following modules, each with its own README file for detailed documentation:

• VMSS Module: Provisions the Virtual Machine Scale Set and configures the self-hosted agents.
• Networking Module: Sets up the required networking resources.

Refer to each module's README for specific usage and configuration details.
