Today is a good day - we have a cluster!

Today I've installed Ubuntu server 20.04 to the three Raspberry Pis, separated the PoE hats from the Pi's with jumper cables to allow them to fit in the enclosure  (the top one fits fine, so no need to move that one), connected all three to my PoE switch, renaming them and reserving their IPs as I went.

Then I installed the microK8s snap to all of them, and joined the second and third nodes to the first, making it the master node.

I'm over the moon that I've finally got one up and running. Hopefully in the next few weeks I will be filling the 4th slot in this case with an 8gb Pi 4. This will make this little beaut a 16 core 16gb RAM box.

Next step is to get some .NET Core apps running.
