See earlier article on basic iPXE booting for more details.

Turns out, there’s an even easier way. Pixiecore is a simple open source tool that makes netbooting trivial.

1. Make sure your router isn’t serving any PXE boot or TFTP related options. It won’t be by default, so if you have not configured any of this - do not configure any of this.
2. Install pixiecore with go install go.universe.tf/netboot/cmd/pixiecore@latest
3. Run $GOPATH/pixiecore quick xyz --dhcp-no-bind
4. Boot a machine on the same network, and it will now load to Netboot.xyz for you to pick an OS. That’s what the xyz argument in the command is for, but many other operating systems like CentOS and Debian are included out of the box.

No need to run a TFTP server, no need to configure your router, just run pixiecore. Beyond a static setup like showcased above, you can also run pixiecore in API mode, where it will ask a REST API that you implement how to boot a machine, given its MAC address - so you can customise things even further. For inspiration on what you can do with Pixiecore, check out this excellent article from Railway, and this quick mockup on how to do it yourself.
