name	terraform-search-import
description	**WORKFLOW SKILL** — Discover existing Azure resources and bulk import them into Terraform management. WHEN: "terraform import", "import Azure resources", "bring unmanaged infra under Terraform", "adopt Terraform for existing resources", "generate import blocks". DO NOT USE FOR: Bicep code (azure-bicep-patterns), new resource creation (terraform-patterns), architecture decisions (azure-adr).
compatibility	Manual workflow requires azurerm ~> 4.0 + Azure CLI. Search workflow requires Terraform >= 1.14 (experimental for azurerm).

Terraform Search & Import for Azure

Discover existing Azure resources and generate Terraform configuration for bulk import.

• Terraform Search (TF 1.14+)

Decision Tree

┌─ Identify target Azure resources
│
├─ PRIMARY: Manual Discovery via az CLI (always works)
│  └─ az resource list → create import blocks → terraform plan → apply
│
└─ SECONDARY: Terraform Search (EXPERIMENTAL)
   ├─ Check: terraform version >= 1.14?
   │  └─ NO → use Manual workflow
   ├─ Check: azurerm supports list_resource_schemas for this type?
   │  └─ UNKNOWN/NO → use Manual workflow
   └─ YES to both → use Search workflow

Primary workflow = Manual Discovery via az CLI. Always works with azurerm ~> 4.0.

Search workflow is experimental — azurerm provider support for list_resource_schemas is TBD. Use Manual Discovery as the reliable default.

Rules

• Manual Discovery is the primary path — always works with azurerm ~> 4.0 and Azure CLI; Terraform Search is experimental and provider support is TBD
• Pin provider to ~> 4.0 — azurerm 4.x renamed many attributes (allow_blob_public_access → allow_nested_items_to_be_public, etc.); pinning to anything else causes drift after import
• Plan before apply — always run terraform plan after generating import blocks; the plan should show import actions ONLY (no creates / destroys)
• Adopt AVM modules post-import — raw azurerm_* is acceptable as a temporary state; refactor to Azure/avm-res-* modules with moved {} blocks (see terraform-patterns references/refactor-module.md)
• Document the source — in the imported resource block, comment the originating az resource list query so future runs can be reproduced
• Out of scope: Bicep code (use azure-bicep-patterns), new resource creation (use terraform-patterns), architecture decisions (use azure-adr)

Manual Discovery Workflow (Primary)

Three-step procedure: (1) discover existing resources via az resource list (by resource group, tag, or type-specific commands like az vm list); (2) generate resource + import blocks for each (full examples and bulk import scripts in references/manual-import.md); (3) terraform plan (review: imports only — no creates / destroys) → terraform apply.

Import ID format: /subscriptions/{sub}/resourceGroups/{rg}/providers/{type}/{name}. The Azure-type ↔ Terraform-resource ↔ az CLI mapping table for the 8 most common services lives in references/manual-import.md.

Post-Import: Adopt AVM Modules

After importing raw azurerm_* resources, refactor to AVM modules using moved {} blocks. See terraform-patterns skill references/refactor-module.md for guidance.

Integration with Terraform MCP

Use Terraform MCP tools during import workflows:

Tool	Purpose
mcp_terraform_search_providers	Validate resource type support in provider
mcp_terraform_get_provider_details	Get resource schemas and import ID format
mcp_terraform_search_modules	Find AVM modules for post-import refactoring
mcp_terraform_get_latest_module_version	Get latest AVM module version

---

Terraform Search Workflow (Experimental)

Warning: Requires Terraform >= 1.14 and azurerm provider support for list_resource_schemas (TBD). Use Manual Discovery above as primary path.

Uses .tfquery.hcl files with list blocks to discover resources, then terraform query -generate-config-out=imported.tf to generate config. Clean generated output by removing computed attrs, adding variables, applying CAF naming.
