Official Documentation

Helios provides base images for multiple key Linux distributions, optimized to be as small as possible to:

• Reduce pull times
• Minimize the attack surface
• Lower data transfer costs

These images are lightweight, efficient, and ready to use across environments like Docker, Kubernetes, and more.

Some key points about Helios:

• Base Images: Designed as base images for Selkies-compatible deployments.
• Extremely Minimal Desktops: Images are intentionally minimal; avoid adding software directly. Instead, extend via the FROM instruction in your Dockerfile.

🏷️ Versioning

Helios uses its own versioning scheme independent of the underlying distro versions. The format is: v0.0.0-codename where codename represents the underlying distro. This allows tracking Helios changes separately from distro updates.

Examples

Helios Version	Distro
v0.0.0-bookworm	Debian 12 (Bookworm)
v0.0.0-noble	Ubuntu 24.04
v0.0.0-jammy	Ubuntu 22.04
v0.0.0-kali	Kali Linux
v0.0.0-rocky-9	Rocky Linux
v0.0.0-alma-9	Alma Linux
