CapivaraOS HERD

CapivaraOS HERD is the server line of CapivaraOS: a headless Linux system (no graphical desktop), based on Fedora 44, meant to run on physical servers, virtual machines and the cloud — with a Brazilian identity, sane security by default, and Cockpit as the browser-based administration console.

Community Edition 1.0.0

This documentation covers HERD Community, the free and open-source edition. Architecture x86_64 (aarch64 support arrives in 1.1).

The idea: herd = fleet

In CapivaraOS, capybaras live in a herd — and that is how we think about servers: a fleet that works together. HERD delivers a predictable, hardened and easy-to-administer server base, whether it is a single node or many.

What's in HERD Community

Two ways to install

  • Installer ISO (bare-metal)

    To install on a physical server or VM from scratch, with the Anaconda text installer.

    Install via ISO

  • qcow2 image (cloud/VM)

    To spin up quickly on cloud or virtualization, with cloud-init handling the user, SSH key and network.

    Cloud/VM deployment

Where to start

  1. Requirements — what the server needs.
  2. Download and verify — get the image and check its integrity.
  3. Install via ISO or cloud/VM.
  4. Getting started — access, network, updates.
  5. Web console (Cockpit) — administer from the browser.
  6. Security and compliance — what's hardened and how to audit.

Already installed?

Jump to Getting started or the Web console (Cockpit).
