I have taken a deployment template from azure and added this to a deployment project in Visual Studio 2015. When the Resource Group is made and deployed, everything works well except for the Web Site connectionstrings.
I have TableStorage, DocumentDb, and Redis instances all being created by this and cannot figure out how to get the Primary Connection String and Primary Key of these items so that I don't have to go in by hand and add them.
looking at the ARM Template Functions ListKeys should do the trick, but after deployment the value is empty. Furthermore, trying a simple string (TestConnectionString) also adds the name, but not the value.
{
"type": "Microsoft.Web/sites",
"kind": "app",
"name": "[parameters('WebAppName')]",
"apiVersion": "2015-08-01",
"properties": {
"name": "[parameters('WebAppName')]",
"resources": [],
"siteConfig": {
"connectionstrings": [
{
"name": "DocumentDbKey",
"value": "[listKeys(resourceId('Microsoft.DocumentDB/databaseAccounts', parameters('docDbName')), '2015-11-06').primaryMasterKey]",
"type": "Custom"
},
{
"name": "TestConnectionString",
"value": "dummystring:pleaseignore;",
"type": "Custom"
}
]
}
},
"dependsOn": [
"[resourceId('Microsoft.DocumentDB/databaseAccounts', parameters('docDbName'))]",
]
}
As your description we can use ARM Template Functions ListKeys to get the Keys. And we could use the following template code to set the connection string. I test Azure storage connection string and Document DB key, It works correctly for me , please have a try. The following is my detail steps:
1.Create Basic Azure Resource Group project with template WebApp
2.From demo remove the unnecessary resource.
3.Add the connection string setting
Deploy the Website
Check the result from the portal
Full template code:
Update:
We could get more useful info about ARM template from the azure resource.
