Terraform adapter

Multi-cloud, existing TF state, organization standardized on Terraform.

Templates

Emit three code files to examples/terraform/:

• main.tf — provider, RG, VNet, subnet, NSG (SSH allow), public IP, NIC, Linux VM
• variables.tf — typed input variables with defaults
• outputs.tf — vm_id, public_ip

Always emit examples/terraform/README.md (Plan Card, prereqs, quickstart, variables table, outputs, cleanup). When the user requests a PR (Mode C), the same README becomes the PR body.

Deploy

terraform init
terraform plan  -var "vm_name={vmName}" -var "admin_public_key=$(cat ~/.ssh/id_rsa.pub)" \
                -var "subscription_id=$AZ_SUB" -var "resource_group_name={resourceGroup}"
terraform apply -var "vm_name={vmName}" -var "admin_public_key=$(cat ~/.ssh/id_rsa.pub)" \
                -var "subscription_id=$AZ_SUB" -var "resource_group_name={resourceGroup}"

VMSS

Replace azurerm_linux_virtual_machine with azurerm_linux_virtual_machine_scale_set (or Windows variants). Add instances, upgrade_mode = "Manual" | "Automatic" | "Rolling". NIC moves inline inside the scale set resource via network_interface { ip_configuration { ... } }.

Notes

• Provider version pinned to ~> 4.0 — bump deliberately, not implicitly.
• admin_public_key is sensitive = true; don't print it.
• zone is "" by default (regional); to pin, pass "1", "2", or "3".
• Pre-check quota with compute_vm_check-quota before terraform apply.
