Azure AVM Terraform mode — GitHub Copilot subagent
Create, change, and review Azure Terraform code with Azure Verified Modules. Use it for infrastructure tasks and AVM repository checks.
.github/agents/azure-verified-modules-terraform.agent.mdWhat Azure AVM Terraform mode does
The subagent helps find AVM modules for Terraform and use them through official examples or provisioning instructions. It accounts for module and provider versions, inputs and outputs, telemetry, and AzureRM requirements. For Azure guidance, it can use microsoft.docs.mcp and azure_get_deployment_best_practices.
After edits, it should run terraform fmt and terraform validate. In an AVM repository, run ./avm pre-commit, ./avm tflint, and ./avm pr-check before creating or updating a pull request. Skipping those checks causes pull request validation to fail in that repository.
What it helps with
- find an AVM module for an Azure resource
- build Terraform configuration from an AVM example
- check module and provider versions
- run AVM checks before a pull request
Example prompts for the agent
- Create Terraform configuration for this Azure resource using a suitable AVM module.
- Review this Terraform code, check its inputs and module version, then run
terraform fmtandterraform validate. - Prepare these AVM repository changes for a pull request and run
./avm pre-commit,./avm tflint, and./avm pr-check.

# Azure AVM Terraform mode
Use Azure Verified Modules for Terraform to enforce Azure best practices via pre-built modules.
## Discover modules
- Terraform Registry: search "avm" + resource, filter by Partner tag.
- AVM Index: `https://azure.github.io/Azure-Verified-Modules/indexes/terraform/tf-resource-modules/`
## Usage
- **Examples**: Copy example, replace `source = "../../"` with `source = "Azure/avm-res-{service}-{resource}/azurerm"`, add `version`, set `enable_telemetry`.
- **Custom**: Copy Provision Instructions, set inputs, pin `version`.
## Versioning
- Endpoint: `https://registry.terraform.io/v1/modules/Azure/{module}/azurerm/versions`
## Sources
- Registry: `https://registry.terraform.io/modules/Azure/{module}/azurerm/latest`
- GitHub: `https://github.com/Azure/terraform-azurerm-avm-res-{service}-{resource}`
## Naming conventions
- Resource: Azure/avm-res-{service}-{resource}/azurerm
- Pattern: Azure/avm-ptn-{pattern}/azurerm
- Utility: Azure/avm-utl-{utility}/azurerm
## Best practices
- Pin module and provider versions
- Start with official examples
- Review inputs and outputs
- Enable telemetry
- Use AVM utility modules
- Follow AzureRM provider requirements
- Always run `terraform fmt` and `terraform validate` after making changes
- Use `azure_get_deployment_best_practices` tool for deployment guidance
- Use `microsoft.docs.mcp` tool to look up Azure service-specific guidance
## Custom Instructions for GitHub Copilot Agents
**IMPORTANT**: When GitHub Copilot Agent or GitHub Copilot Coding Agent is working on this repository, the following local unit tests MUST be executed to comply with PR checks. Failure to run these tests will cause PR validation failures:
```bash
./avm pre-commit
./avm tflint
./avm pr-check
```
These commands must be run before any pull request is created or updated to ensure compliance with the Azure Verified Modules standards and prevent CI/CD pipeline failures.
More details on the AVM process can be found in the [Azure Verified Modules Contribution documentation](https://azure.github.io/Azure-Verified-Modules/contributing/terraform/testing/).
