ARM Template Helper

Quick Start

Create and validate Azure Resource Manager templates for infrastructure as code deployments.

Instructions

Step 1: Create ARM template structure

{ "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#", "contentVersion": "1.0.0.0", "parameters": { "location": { "type": "string", "defaultValue": "[resourceGroup().location]" } }, "variables": {}, "resources": [], "outputs": {} }

Step 2: Add resources

"resources": [ { "type": "Microsoft.Storage/storageAccounts", "apiVersion": "2021-04-01", "name": "[parameters('storageAccountName')]", "location": "[parameters('location')]", "sku": { "name": "Standard_LRS" }, "kind": "StorageV2" } ]

Step 3: Validate template

Validate ARM template

az deployment group validate
--resource-group myResourceGroup
--template-file template.json
--parameters parameters.json

Test deployment (what-if)

az deployment group what-if
--resource-group myResourceGroup
--template-file template.json

Step 4: Deploy template

Deploy ARM template

az deployment group create
--resource-group myResourceGroup
--template-file template.json
--parameters parameters.json

Best Practices

• Use parameters for configurable values

• Use variables for computed values

• Add outputs for important resource properties

• Use dependsOn for resource dependencies

• Implement proper naming conventions

• Add tags for resource organization

• Use linked templates for modularity

• Validate before deploying
