Registering Azure Local (formerly known as Azure Stack HCI) with Azure has come leaps and bounds from the early days that I remember all too well. The process has now been simplified to a one-liner that will prompt you for Azure authentication (via Device Code) and will then start registering the node with Azure Arc to your desired resource group on your Azure subscription. Although that is great, the one thing I’m constantly asked for is guidance on how to do this via a Service Principal (app registration), or SPN for short, with the required permissions.
There are many reasons why someone would want to do this. Some of the common reasons have to deal with a company’s Azure security policy preventing them from using a device code to authenticate to Azure from an unmanaged host. Another reason may be simply because they are wanting to automate end-to-end a deployment of an Azure Local cluster (or multiple clusters).
If you find yourself in that scenario, the below will aim to provide you with some helpful code blocks that my team leverages to perform end-to-end Azure Local deployments for our validation efforts.
