`I have a storage account called STGaccount which I created with the Azure portal and would like to use ARM template to create a container called inputcontainer in this STGaccount. Each time I try to do so I get an error message saying that the storage account STGaccount I am trying to create with the ARM template already exist in the resource group....So i guess I am writing my ARM template in a way that it still creates a new storage account with a name similar to the one I already have in the resource group. What I actually want to do is to reference the already existing storage account in my ARM template such that i do not have to create a new one. Thanks in advance as I look forward to your response

Try this ARM template, this will help you to create a container in the existing Storage account.
