So after getting things working with AWS, I decided to quickly turn things around to focusing on Microsoft Azure and AKS clusters.
Essentiallly for this one, after testing the official Azure CLI docker image, I decided I didn't need to build my own.
I did add some extra bits into this work and understand how I can grab the SSH keys generated by the Azure CLI command line for the AKS deployment, from the container where the tasks run in vRA.
