They have done a wonderful job so far. The ui is very nice, and everything in virtualization is very smooth, and shares and storage work nicely. Apps are not the best UX though. Aside from the fact that I can't seem to get any working, downloading docker images is confusing: it is unclear how the connection string should be built for authenticated registries.
My first attempt I got an error saying kubernetes service wasn't running, so I checked services and it wasn't listed, then after a few more tries it let me create the app, but it seems to be stuck forever in the deploying faze. I tried to simply launch a base alpine container: I was going to install ssh in it and start testing nodeports, dns etc. But I ended up with the alpine container stuck "deploying" forever.
I also tried installing Minio from the official charts, that says it is installed but it won't start. Alpine container is similarly unresponsive: I can't even stop the deployment I let it run while I ate dinner, after a few reboots and a couple hours I just ended up deleting then as they were frozen.
Probably an issue with kubernetes, I'll open a shell and check it out when I get a chance.
Testing on a mini itx board pulled from a TrueNAS Mini XL+ ( All I really did was put it in a small aftermarket 2U rackmount chassis so we would stop tripping over it)
