This section covers taking us from hardware to a functional k3s cluster and initial services setup.

The basic proceedure for installing this software is :

  • generate files for the cluster
  • flash your USB drive with Ubuntu 21.10 using Rasberry Pi Imager.
  • copy the appropriate user-data file to the USB drive
  • plug the USB drive into your rasberry pi
  • power up the rasberry pi
    • wait while the computer bootstraps itself.

The only file that needs to be modified is the cluster_config, there is a file scripts/fixtures that helps to manage all of the environment variables when the script needs them. If there are any problems with your generated files (missing spots), check there first.
