A Collection of Cloud-Native Enterprise Linux OS Images

Bootc-based desktop Linux images built on AlmaLinux, CentOS Stream, and Fedora

🚀 About TunaOS

TunaOS is a curated collection of bootc-based desktop operating systems built on modern container technology. The goal is to bring a modern desktop experience to Enterprise Linux — stable, immutable, and up-to-date. Inspired by Bluefin and the Universal Blue community.

Features

• Modern Desktops: GNOME, KDE Plasma, COSMIC, and Niri — your choice, on Enterprise Linux
• Latest GNOME: Don't get stuck on a 3-year-old GNOME. We backport the latest desktop features to the Enterprise Desktop
• Homebrew: Baked into the image — all your CLI apps and fonts are just a brew command away
• Flathub by Default: Full Flathub access out of the box — get any Flatpak available on the net
• HWE Option: Hardware Enablement kernel for newer hardware support
• GDX Option: NVIDIA drivers and CUDA for graphics and AI workflows

🛠️ Installation

Use a pre-built ISO

ISOs are published every two weeks for gnome and gnome-hwe flavors of Yellowfin and Albacore:

Variant	GNOME	GNOME (HWE)
Albacore	albacore-gnome-latest.iso	albacore-gnome-hwe-latest.iso
Yellowfin	yellowfin-gnome-latest.iso	yellowfin-gnome-hwe-latest.iso

Build your own ISO or VM image

Use bootc-image-builder directly:

# ISO
sudo podman run --rm -it --privileged \
  -v /var/lib/containers/storage:/var/lib/containers/storage \
  ghcr.io/osbuild/bootc-image-builder:latest \
  --type iso \
  ghcr.io/tuna-os/yellowfin:gnome

# QCOW2 (VM image)
sudo podman run --rm -it --privileged \
  -v /var/lib/containers/storage:/var/lib/containers/storage \
  ghcr.io/osbuild/bootc-image-builder:latest \
  --type qcow2 \
  ghcr.io/tuna-os/yellowfin:gnome

Switch an existing system

If you're already running a compatible bootc system:

sudo bootc switch ghcr.io/tuna-os/yellowfin:gnome

🧪 Current Status

Note: These images are in active development. Yellowfin and Albacore are the most mature variants. Bonito (Fedora) still needs work.
