# pxe-boot
|
|
|
|
The `pxe-boot` host serves HTTP boot assets for iPXE clients.
|
|
|
|
## Host Role
|
|
|
|
- Hostname: `pxe-boot`
|
|
- Web service: nginx on TCP port 80
|
|
- PXE root: `/srv/pxe`
|
|
- Generated iPXE menu: `/srv/pxe/boot/menu.ipxe`
|
|
- Boot binaries copied from the Nix `ipxe` package:
|
|
- `/srv/pxe/boot/ipxe.efi`
|
|
- `/srv/pxe/boot/undionly.kpxe`
|
|
|
|
## Directory Layout
|
|
|
|
The host creates these directories with systemd tmpfiles:
|
|
|
|
```text
|
|
/srv/pxe
|
|
/srv/pxe/boot
|
|
/srv/pxe/nixos
|
|
/srv/pxe/ubuntu
|
|
/srv/pxe/rescue
|
|
```
|
|
|
|
The generated menu currently exposes entries for:
|
|
|
|
- NixOS installer
|
|
- Rescue environment
|
|
- iPXE shell
|
|
- Reboot
|
|
|
|
Kernel and initrd artifacts for installer or rescue entries must be placed under
|
|
the matching `/srv/pxe/<entry>/` directories by an operator or a separate build
|
|
process. This repository defines the service and menu, not the installer images.
|
|
|
|
## Validation
|
|
|
|
Safe evaluation check:
|
|
|
|
```bash
|
|
nix eval .#nixosConfigurations.pxe-boot.config.system.build.toplevel.drvPath --raw
|
|
```
|
|
|
|
After deployment by an operator, basic service checks are:
|
|
|
|
```bash
|
|
curl http://pxe-boot/boot/menu.ipxe
|
|
curl -I http://pxe-boot/boot/ipxe.efi
|
|
curl -I http://pxe-boot/boot/undionly.kpxe
|
|
```
