createClusterAKSLong = templates.LongDesc(`
This command creates a new Kubernetes cluster on AKS, installing required local dependencies and provisions the
Jenkins X platform
Azure Container Service (AKS) manages your hosted Kubernetes environment, making it quick and easy to deploy and
manage containerized applications without container orchestration expertise. It also eliminates the burden of
ongoing operations and maintenance by provisioning, upgrading, and scaling resources on demand, without taking
your applications offline.
Please use a location local to you: you can retrieve this from the Azure portal or by
running "az provider list" in your terminal.
Important: You will need an account on Azure, with a storage account (https://portal.azure.com/#create/Microsoft.StorageAccount-ARM)
and network (https://portal.azure.com/#create/Microsoft.VirtualNetwork-ARM) - both linked to the resource group you use
to create the cluster in.
