Infra Provisioning using ARM Templates

• Azure supports infraprovisioning in 3 popular ways
  • ARM Templates:
    • This is written in json
  • Azure Bicep
  • Azure Provider in Terraform
• ARM Templates can be applied at resource group or subscription or management group level
• Refer Here for creating an ARM Template from vscode
• Ensure extenison is installed
  
• resource definitins Refer Here
• Template reference Refer Here
• ARM Template resource syntax for virtual network Refer Here
• Create a new folder and any json file. Add vnet as discussed in the class

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
        {
            "type": "Microsoft.Network/virtualNetworks",
            "apiVersion": "2023-04-01",
            "name": "test",
            "location": "East US",
            "properties": {
                "addressSpace": {
                    "addressPrefixes": ["192.168.0.0/16"]
                }
            }
        }
    ]
}

• Create a new resource group and deploy custom template
