tftp-pxe-server

A modern TFTP PXE server designed for booting multiple Raspberry Pis. This works regardless if you're using a Pi 3B (non-plus) with the OTP bit set or a modern Raspberry Pi 4.

This wouldn't be possible without the awesome https://github.com/pin/tftp library!

By default, tftp-pxe-server serves files within a subdirectory based on the IP address of the requestor.

Instead of booting the Pi and figuring out the serial number for subdirectories, make boot subdirectories based on the static IP address you have in your DHCP server. Raspberry Pi 3B's don't ask for a TFTP path under their serial number, and not everyone uses dnsmasq-tftp in proxy mode for mac address mode.

Getting Started

NOTE: 10.0.0.5 asking for bootcode.bin by default will read ./10.0.0.5/bootcode.bin.

Use the pre-built docker image like so:

docker run --name=tftp-pxe-server \
    -it -d \
    --restart=unless-stopped \
    --network=host \
    -v $PWD/tftproot:/tftproot
    ghcr.io/jrcichra/tftp-pxe-server
    -directory /tftproot

Change the left side of -v to your TFTP root directory.
