Linux Image Factory

Linux Image Builder

Create reproducible Linux images for fleets, homelabs, self-hosted stacks, and controlled infrastructure.

Start a buildFleet management

OpenFactory is a Linux image builder for teams that want operating systems to be specified, reviewed, rebuilt, tested, and deployed like product artifacts instead of assembled by hand on each machine.

Build images from requirements

Most image work starts as scattered requirements: install Docker, enable SSH, pin a service, add a non-root operator, harden the system, expose metrics, and prove the service listens after boot. OpenFactory turns those requirements into a repeatable build path.

  • Golden images for teams that need a reviewed Linux baseline.
  • Immutable-ish appliance images for routers, kiosks, and edge nodes.
  • Homelab and self-hosted stacks that boot into a known topology.
  • Compliance-oriented images with tests and evidence attached.

From builder to pipeline

A Linux image pipeline should make change visible. Recipes, prompts, package lists, service declarations, and test scenarios become the review surface. When the image changes, the build reruns and the same assertions prove the new system still behaves as expected.

For application repositories, connect that flow to bootable ISO builds from GitHub. For larger operating models, pair image building with Linux fleet management.

Image builder use cases

Standard developer workstation with Docker, SSH, GPU drivers, and monitoring.
Self-hosted app stack with reverse proxy, database, cache, and backup node.
Edge gateway with VPN, DNS, MQTT, firewall policy, and health checks.
Regulated workstation with approved packages and verification evidence.

Frequently asked questions

What is a Linux image builder?

A Linux image builder creates repeatable operating system images from a declared set of packages, users, services, configuration, and tests. The output can be a bootable ISO, VM image, or other deployable system artifact.

What is a golden image in Linux?

A golden image is a reviewed base system that other machines are cloned or deployed from. It usually includes approved packages, hardening, baseline monitoring, users, and compliance controls.

Can OpenFactory fit into CI/CD for Linux images?

Yes. OpenFactory recipes and prompt outputs can be treated as build inputs, then rebuilt and validated when packages, services, or policy change. The goal is to make OS changes reviewable like application changes.
