So I've been testing bits and pieces individually.
For example, I made a custom image for the VMSS nodes, which is based on Ubuntu and has multiple CUDA versions installed, as well as conda and docker pre-installed.
I'm managed to test the setup script, so that it executes on a pristine node, and results in a compute node being added to the relevant queue, but that's been executed manually by me, as I have the credentials to log on via SSH.
And I had to do things get the clearml-server the manual way.

Hopefully once things calm down at work I will find more time.
