Last night, I tore down the entire stack and rebuilt it. This was to accommodate two things:
- The release of Ubuntu 20.04, which required an upgrade, and
- A hardware change involving using USB flash drives for the root file system on all nodes, rather than just a micro SD card.
As a result of this, I’ve come up with some changes to node provisioning – the steps required to go from bare hardware to an operating node. I’m planning a step-by-step guide for building out the cluster based on this. Stay tuned.
