We have a Azure subscription, one of my colleague's azure user account is working fine. He has created Registry as well as he has deployed a hello world image in it using azure cli.
But when i click on Azure Cloud shell, it prompts for resource group and storage account. even after selecting existing resource group and storage account that my colleague has created, there is one more mandatory field file share.
Whats the importance of it and can we give any name to it? is that also chargeable?
