Create a resource group with the az group create. An Azure resource group is a logical container into which Azure resources like function apps, databases, and storage accounts are deployed and managed.
The following example creates a resource group named myResourceGroup.
If you are not using Cloud Shell, sign in first using az login.
az group create --name myResourceGroup --location westeurope
You generally create your resource group and the resources in a region near you. To see all supported locations for App Service plans, run the az appservice list-locations command.
