    # iPXE with Netboot.xyz

    Leverage Docker and Netboot.xyz to host Harvester/Rocky/Liberty installers and kickstart.

    ## Deploy Netboot with Docker

    - install docker
    - create directories `mkdir /opt/netboot/{config,assets}`
    - deploy with `docker compose -f docker_compose.yaml up -d`
    - Add `menu.ipxe` to `/opt/netboot/config/menus/menu.ipxe` from below.
    - Add assets to `/opt/netboot/assets/` directory, aka unpack ISOs to directory.

    ## look at attached files

    Take a look at the tree output below. I truncated to show the important files.

    ## Video coming soon.
