How do I make decisions based on presence of resource in Azure inside ARM?

Question

I need my ARM template to use conditional statement based on presence of Azure Files share. How do I find out if fileshare exists inside ARM to deploy certain other types of resources based on that?

Answer 1

There's no simple way to do this... ARM is declarative and should be idempotent. But you could work around the scenario by using a deploymentScript to check existence.
