I'm getting k3s fettled up again. I've got a VM (tayet) as the server, and a couple of fallow Raspberry Pis as agent nodes. Still not sure what I want to do with a k3s cluster. There's a bunch of stuff to install like step-ca that are services one should have running in your cluster, but I'm working on folding my website down to a monolith, so I don't have that many actual applications.
On the other hand, there is a reasonable chance that we're going to get fast symetric fibre in a couple of months (when the BT contract ends), I'm tempted to bring most of my hosting back home, on principal. Of course, I still need a cloud endpoint for the reputation, and splitting services between cloud and house makes them both slower and less reliable.
Sigh, again. 20 year old me would have gone crazy at the idea of symetric gigabit fibre to the home, but I think husband may be right and we just don't need that kind of bandwidth.
