I faced with this issue two times. First in the 2015 and last today in May of 2017.
I need to add connection strings to the WebApp - I want to add strings automatically from generated resources during deployment from the ARM template. It can help later to not add manually this values.
First time I used old version of the function listKeys (it looks like old version returns result not as object but as value):
"AzureWebJobsStorage": {
"type": "Custom",
"value": "[concat(variables('storageConnectionString'), listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName')), '2015-05-01-preview').key1)]"
},
Today last version of the working template is:
"resources": [
{
"apiVersion": "2015-08-01",
"type": "config",
"name": "connectionstrings",
"dependsOn": [
"[resourceId('Microsoft.Web/Sites/', parameters('webSiteName'))]"
],
"properties": {
"DefaultConnection": {
"value": "[concat('Data Source=tcp:', reference(resourceId('Microsoft.Sql/servers/', parameters('sqlserverName'))).fullyQualifiedDomainName, ',1433;Initial Catalog=', parameters('databaseName'), ';User Id=', parameters('administratorLogin'), '@', parameters('sqlserverName'), ';Password=', parameters('administratorLoginPassword'), ';')]",
"type": "SQLServer"
},
"AzureWebJobsStorage": {
"type": "Custom",
"value": "[concat(variables('storageConnectionString'), listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageName')), '2016-01-01').keys[0].value)]"
},
"AzureWebJobsDashboard": {
"type": "Custom",
"value": "[concat(variables('storageConnectionString'), listKeys(resourceId('Microsoft.Storage/storageAccounts', parameters('storageName')), '2016-01-01').keys[0].value)]"
}
}
},
Thanks.
