netboot
PXE provisioning management: describe your netboot targets, images and DHCP
zones in config, and let netboot render the per-target boot artifacts and arm (or
disarm) DHCP for a machine as it enters and leaves the install process.
netboot is a small, hook-driven engine. A YAML config declares targets
(host/MAC/IP), images (what to boot), dhcp zones (the network a target
lives on) and content repos (where artifacts are fetched/served from). For a
given target netboot builds a render context and produces netboot files from
Jinja2 or shell-style templates, resolving names by MAC, hostname or IP with
sensible fallbacks. Backends and behaviour are extensible through an event-hook
system and pluggable DhcpServer handlers.
Install
pip install netboot # provides the `pixie` command
# or, from a checkout:
pip install .
Optional extras:
| Extra | Enables |
|---|---|
netboot[config] |
YAML config loading for the CLI (pyyaml) |
netboot[dns] |
The dnspython resolver backend (best coverage; without it hostname targets still resolve via the system/nslookup fallbacks) |
netboot[docs] |
Build the documentation site (mkdocs) |
Built on duho (CLI/args/command discovery),
pathlib_next (URI-aware paths),
yaconfiglib (layered YAML), and
Jinja2. IP/MAC/DNS helpers come from
netimps, re-exported as
netboot.utils.net.
CLI
The command is pixie (PXE is pronounced "pixie"); netboot is the library
package it drives.
# Initiate the PXE process for a target (render artifacts + arm DHCP):
pixie initiate my-host
# Complete it (post-boot cleanup, disarm DHCP):
pixie complete my-host
Global options:
| Option | Purpose |
|---|---|
-c, --config PATH |
Explicit config file (yaml/cfg) |
--baseconfig DIR |
Base config directory to search (default ./config) |
-l, --load-module M |
Import module(s) before building netboot (config/hook deps) |
--cmdspath PATH |
Extra directories/packages to search for commands |
A target is looked up by exact id, or by hostname prefix / MAC / IP.
Library
from netboot import Pixie
pixie = Pixie(**config) # config: the merged YAML mapping
target = pixie.lookup_target("my-host")
ctx = pixie.make_context(target) # render context (image + dhcpzone + target)
print(ctx.render("boot.ipxe.j2")) # render a template against the context
pixie.initialize(target) # arm DHCP for the target
pixie.complete(target) # cleanup once installed
Extending
- Hooks. Pass
hooks=[...](callables or"module.func"import strings) toPixie(...). Each hookf(event, netboot, value, kwargs) -> valueis called for everyPixieEventand may transform the value flowing through it — used to customise lookup, context construction and the init/complete lifecycle. - DHCP backends. Subclass
netboot.dhcp.DhcpServer; the lowercased class name is the URI scheme it handles (class dnsmasq(DhcpServer)→dnsmasq://...). Import your plugin module via--load-moduleso it is registered before the config builds the zones.
