How to use parameter value inside the siteconfig in ARM template? - json

Question

I have below code for the create function app :
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.1",
"parameters": {
"storage_account_name": {
"type": "string",
"defaultValue": "test"
},
"location": {
"defaultValue": "[resourceGroup().location]",
"type": "string"
},
"App_Plan_Name": {
"type": "string",
"defaultValue": "test1"
},
"Function_App_Name": {
"type": "string",
"defaultValue": "funapwp11"
},
"AI_Name": {
"type": "string",
"defaultValue": "appinsiwghts"
},
"Appsetting_For_Fun_App": {
"type": "object",
"defaultValue": {
"client_id": "",
"client_secret": "",
"subscription_id": "",
"tenant_id": "",
"FUNCTIONS_EXTENSION_VERSION": "~4",
"FUNCTIONS_WORKER_RUNTIME": "python"
}
}
},
"variables": {
"unique_Storage_Name": "[concat(parameters('storage_account_name'),uniqueString(resourceGroup().id))]",
//"Unique_App_Service_Name": "[concat(parameters('App_Service_Name'),uniqueString(resourceGroup().id))]",
"Unique_App_Plan_Name": "[concat(parameters('App_Plan_Name'),uniqueString(resourceGroup().id))]",
"Unique_Fun_App_Name": "[concat(parameters('Function_App_Name'),uniqueString(resourceGroup().id))]",
"Unique_AI_Name": "[concat(parameters('AI_Name'),uniqueString(resourceGroup().id))]"
},
"resources": [
{
"type": "Microsoft.Web/sites",
"apiVersion": "2022-03-01",
"location": "[parameters('location')]",
"name": "[variables('Unique_Fun_App_Name')]",
"kind": "functionapp",
"dependsOn": [
"[resourceId('Microsoft.Web/serverfarms', variables('Unique_App_Plan_Name'))]",
"[resourceId('Microsoft.Storage/storageAccounts',variables('unique_Storage_Name'))]",
"[resourceId('Microsoft.Insights/components',variables('Unique_AI_Name'))]"
],
"properties": {
"serverFarmId": "[resourceId('Microsoft.Web/serverfarms',variables('Unique_App_Plan_Name'))]",
"httpsOnly": true,
"enabled": true,
"adminEnabled": true,
"sku": "Basic",
"siteProperties": {
"properties": [
{
"name": "LinuxFxVersion",
"value": "Python|3.9"
},
{
"name": "WindowsFxVersion",
"value": null
}
]
},
"siteConfig": {
"linuxFxVersion": "Python|3.9",
"alwaysOn": true,
"pythonVersion": "3.9",
"appSettings": [
{
"name": "APPINSIGHTS_INSTRUMENTATIONKEY",
"value": "[reference(resourceId('Microsoft.Insights/components', variables('Unique_AI_Name'))).InstrumentationKey]"
},
{
"name": "APPLICATIONINSIGHTS_CONNECTION_STRING",
"value": "[reference(resourceId('Microsoft.Insights/components',variables('Unique_AI_Name')),'2020-02-02-preview').ConnectionString]"
},
{
"name": "AzureWebJobsStorage",
"value": "[format('DefaultEndpointsProtocol=https;AccountName={0};EndpointSuffix={1};AccountKey={2}', variables('Unique_Storage_Name'), environment().suffixes.storage, listKeys(resourceId('Microsoft.Storage/storageAccounts', variables('Unique_Storage_Name')), '2021-08-01').keys[0].value)]"
}
]
}
}
}
]
}
I want use Appsetting_For_Fun_App parameter inside the properties >> siteConfig >> appSettings.
Parameter:
"Appsetting_For_Fun_App": {
"type": "object",
"defaultValue": {
"client_id": "",
"client_secret": "",
"subscription_id": "",
"tenant_id": "",
"FUNCTIONS_EXTENSION_VERSION": "~4",
"FUNCTIONS_WORKER_RUNTIME": "python"
}
}
I need like that
"appSettings": [
{
"name": "[parameters('Appsetting_For_Fun_App')]",
"value": "[parameters('Appsetting_For_Fun_App')]"
},
I have tried multiple way but no luck.
You can refer the question: Azure resource manager template website app settings

Answer 1

Two options I can think of:
format the parameter as an object array - then no transform is needed in the template...
"parameters": {
"Appsetting_For_Fun_App": {
"type": "array",
"defaultValue": [
{
"name": "client_id",
"value": ""
},
{
"name": "client_secret",
"value": ""
},
{
"name": "subscription_Id",
"value": ""
}
]
}
And then on the web app:
"siteConfig": {
"linuxFxVersion": "Python|3.9",
"alwaysOn": true,
"pythonVersion": "3.9",
"appSettings": "[parameters('Appsettings_For_Fun_App')]"
but you can also do it via:
transform in the template, simplest to illustrate using a variable:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"myValues": {
"type": "object",
"defaultValue": {
"setting1": "value1",
"setting2": "value2",
"setting3": "value3"
}
}
},
"variables": {
"copy": [
{
"name": "foo",
"count": "[length(items(parameters('myValues')))]",
"input": {
"name": "[items(parameters('myValues'))[copyIndex('foo')].key]",
"value": "[items(parameters('myValues'))[copyIndex('foo')].value]"
}
}
]
},
"resources": [],
"outputs": {
"bar": {
"type": "array",
"value": "[variables('foo')]"
}
}
}
