Thanks all. Specifically my devops role is modernising the release cycle for continuous integration at a financial services company in England. They say they want to change and its I who has the power to recommend tools to do it with, then try make it all work together!
As for unraid. Took me so long because, well, I'm stubborn? I wanted my Ubuntu switch to work and as I said it does, mostly. Looks like I'll be needing to spin up an unraid box before long to take all these new GUIs for a spin. Ironically, I'm more comfy with the command line than ever now but a good GUI has its place.
As v6 nears completion I'm looking forward to giving it a proper go. When I say a set it and forget it box, I really mean it. It must be able to docker and pool my storage, that's it. I'll then be able to free up a different machine as a home lab. Tres exciting.
