Chainguard Containers

description Chainguard Containers Overview

Chainguard Containers provide a secure way to run containerized applications. They utilize small, distroless base images combined with cryptographic verification ensuring image integrity throughout the supply chain. This system is particularly valuable for organizations needing robust security and traceability in their software deployments, including DevOps teams and those focused on critical infrastructure.

help Chainguard Containers FAQ

Why do Chainguard Containers have fewer vulnerabilities than standard Docker images?

Chainguard Containers are built from scratch and stripped of unnecessary packages, such as shells and package managers, drastically reducing the attack surface. By removing these default components, they eliminate hundreds of common vulnerabilities and exposures (CVEs) typically found in standard base images like Debian or Alpine.

Do Chainguard Containers include an SBOM?

Yes, every Chainguard Container comes with a cryptographically signed Software Bill of Materials (SBOM) by default. This allows security and development teams to easily verify the exact contents and provenance of the images.

How do I debug my application if a Chainguard Container doesn't have a shell?

Because Chainguard's minimal images lack a shell for security reasons, debugging is typically done by using a debug variant of the image. You can pull tags appended with '-dev' which temporarily include a shell and package manager for testing purposes.

Can Chainguard Containers be used with Kubernetes?

Yes, Chainguard Containers are standard OCI-compliant images, meaning they run perfectly in any Kubernetes environment. You can simply swap out your existing Alpine or Ubuntu base images in your Dockerfile for a Chainguard equivalent.
