A nix expression to create a netboot k8s cluster of qemu instances.
If you have a bunch of underutilized workstations, run a master VM using this image. Then run worker VMs on the other workstations. The worker will simply netboot from the master, adding another node to the k8s cluster.
The run.sh script will help you with the correct qemu commands to run master and worker.
The main expression is image.nix, which creates the master image.
It takes its config from master-config.nix, which incudes a netboot server serving the image defined in worker-config.nix.
KNOWN BUGS:
- k8s nodes are not yet correctly connected
- nodes probably need more direct networking connection
- working completely in memory will probably not be enought
