Example of Linked ARM template

Main Template:

It has the usual template structure with the following tabs.

1. schema
2. contentVersion
3. parameters
4. resources
5. outputs

You can find the description of these in my previous blog about ARM templates.

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
   //main template parameters
    "StorageContainerSASToken": {
      "type": "string",
      "metadata": {
        "description": "SASToken here Dynamically generated by AzureFileCopyTask"
      }
    },
    "StorageContainerURI": {
      "type": "string",
      "metadata": {
        "description": "Retrieve Azure Storage Container URI"
      }
    },
    "applicationinsight-template-file": {
      "type": "string",
      "metadata": {
        "description": "Specifies Application Insight ARM template file name"
      }
    },
    //Application Insight tempalte parameters
    "AppInsights_name": {
      "type": "string",
      "metadata": {

        "templateLink": {
          "contentVersion": "1.0.0.0",
          "uri": "[concat(parameters('StorageContainerURI'), parameters('applicationinsight-template-file'), parameters('StorageContainerSASToken'))]"
        },
        "parameters": {

            "value": "[parameters('type')]"
          },
          "AppInsights_name": {

    }
  ],
  "outputs": {
    "APPINSIGHTS_INSTRUMENTATIONKEY": {
      "value": "[reference('linkedTemplate_ApplicationInsight').outputs.APPINSIGHTS_INSTRUMENTATIONKEY.value]",

    },
    "App_Id": {
      "type": "string",
      "value": "[reference('linkedTemplate_ApplicationInsight').outputs.App_Id.value]"
    }
  }
}

Note: i will update about the storage container SAS token, Storage container uri parameters soon in my next blog.

Main Parameter:

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    //common paramters
    "StorageContainerURI": {
      "value": ""   
    },
    "applicationinsight-template-file": {
      "value": "NameOfApplicationInsightTemplateFile"
    },
    "location": {
      "value": "West Europe"
    },
    //application insight parameters
    "AppInsights_name": {
      "value": "ExampleOfLinkedTemplate"
    },
    "type": {
      "value": "other"
    }
  }
}

Linked Template:

Below is the template for creating application insight.

   "type": "string",
   "defaultValue": "YourApplicationInsightName"
   },

   },
  "type": {
   "type": "string"
   }
  },
  "variables": {
  },

    }
   }
  ],
  "outputs": {
