Overview of Chainguard OS

Thu, 03 Jul 2025 08:49:31 +0000

Chainguard OS provides a more secure operating system that powers all Chainguard container images, built specifically to address modern supply chain security challenges. Unlike traditional Linux distributions designed for general-purpose computing, Chainguard OS focuses exclusively on container workloads, enabling faster security updates and significantly reduced attack surface.

Chainguard OS adheres to four key principles:

Continuous Integration and Delivery
Nano Updates and Rebuilds
Minimal, Hardened, Immutable Artifacts
Delta Minimization

On this page, we’ll discuss each of these components and how Chainguard OS differs from the operating system status quo.
