createUiDefinition.json: Selecting existing resources

Posted by sseely in Uncategorized on July 19, 2021

I was asked how to use two controls from Create UI definition elements – Azure Managed Applications | Microsoft Docs:

The first control displays a list of resources of a given type and is quite handy. The other calls an Azure REST API and delivers the results. There is no default way to display the results; you need to couple the ArmApiControl with a display if you want to show any values. I wrote the following little createUiDefinition.json file to demonstrate how to use these against something many actively used Azure Subscriptions contains: storage accounts.

All the information is on a blade called bladeData. The first item uses the “easy” path. The second uses the ArmApiControl paired with a dropdown. Both display the list of storage accounts in the customer subscription.
