PXE Provisioning

From Bare Metal to Ready Node

Node discovery, image management and disk-install provisioning on Warewulf 4 — bring a new compute node into production in minutes, even on sites without internet.

Automatic discovery and approval

Nodes booting over PXE land in a discovery queue; approve with one click and installation begins.

Air-gap support

Fully offline installation with local RPM repositories and GPG-signed offline bundles.

What's Inside

Every Provisioning Step in the Panel

From discovery to images, from kickstart to configuration convergence — the whole node lifecycle.

Node Discovery

MAC-based discovery with an approval queue; registration with automatic IP allocation from IPAM.

Disk-Install Kickstart

Installation to disk via anaconda/kickstart; NTP/LDAP/DNS provisioned automatically for Slurm categories.

Image Factory

Build and version OS images from the panel; changes stay traceable.

Image Deployment

Cluster-wide disk-image deployment and image sync — from a single point.

Package Repositories

Generate the Slurm repository from the panel or import it as a GPG-signed offline bundle.

Config Convergence

Node configurations converge declaratively via the agent; drift self-heals on every heartbeat.

Consistent After Installation, Too

Provisioning isn't a one-off task — TULPAR keeps nodes consistent throughout their lifecycle.

The DHCP/TFTP/HTTP provisioning chain runs on Warewulf 4; from PXE boot to OS sources, it's managed from the panel.

Installed nodes receive NTP, LDAP and DNS settings dynamically from the head — no manual config file distribution.

Configurations are distributed with Ed25519 content-bound signatures; the agent applies only verified configs.

The registered → imaging → provisioning → ready flow, with drain, maintenance and recovery states for a complete lifecycle.
