Leverage Docker and Netboot.xyz to host Harvester/Rocky/Liberty installers and kickstart. We have been developing an Harvester Workshop and needed a better way to boot dozens of machines. Netboot.xyz was a simple way to do it. We used https://hub.docker.com/r/linuxserver/netbootxyz to simplify the install.
Then we created a custom menu and loaded the assets. After updating the DHCP settings on the network to point to the machine we are able to boot anything.
