ARM Templates

While creating ARM Templates the JSON structure is defined by Azure
The template syntax/structure Refer Here
Structure

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "",
  "apiProfile": "",
  "parameters": {  },
  "variables": {  },
  "functions": [  ],
  "resources": [  ],
  "outputs": {  }
}

Minimal ARM template (only required values)

{
    "$schema": "",
    "contentVersion": "",
    "resources": []
}

ARM Template Deployments: When we create a template and want to deploy, there are diferent levels of deployment
- Subscription Level => “https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#”
- Resource Group => “https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#”
- Management Group => “https://schema.management.azure.com/schemas/2019-08-01/managementGroupDeploymentTemplate.json#”
- tenant => “https://schema.management.azure.com/schemas/2019-08-01/tenantDeploymentTemplate.json#”
Our deployments are generally resource group level

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "0.0.1",
    "resources": []
}

Refer Here for understanding resources.
Resource structure:

{
    "type": "",
    "apiVersion": "",
    "properties": {

    },
    "arguments": ""
}

To find out resource structure Refer Here
Refer Here for arm template syntax for resource group.
Configure visual studio code: Refer Here
Install ARM Tools extension
