Chainguard Reaches 1 Billion Container Build Manifests, Doubles Output in Six Months
Key points
- Chainguard reached 1 billion container build manifests.
- Output doubled from 500 million in six months.
- Catalog includes over 3,000 unique images and 675,000 image versions.
- Builds are continuous for security and updates.
Milestone Achieved
Chainguard has announced a significant increase in its container build manifest output, reaching over 1 billion manifests. This represents a doubling of its output from 500 million within the last six months. The company's catalog now encompasses more than 3,000 unique container images and 675,000 image versions.
Defining Build Manifests
A "build manifest" is defined as every new, verifiable artifact produced by the Chainguard Factory. This includes new image versions, rebuilds triggered by dependency patches (e.g., libc), new architecture variants, and regenerated Software Bill of Materials (SBOMs) following dependency changes. These events all result in new builds and artifacts.
Continuous Security and Updates
The high volume of manifests reflects Chainguard's approach to maintaining a continuously fresh and secure catalog. Projects like Python, with multiple versions and architectures, are repeatedly rebuilt due to upstream changes, dependency patches, and base image hardening. This ensures images remain secure daily, rather than only on the initial pull.
Underlying Technology
This continuous delivery is powered by Chainguard OS, a Linux operating system designed for cloud-native workloads and continuous software integration. Unlike traditional distributions, Chainguard OS uses a rolling release model, delivering rapid nano-updates and rebuilds throughout the day. The Chainguard Factory infrastructure facilitates this process, ensuring every artifact is built from source with SLSA Level 3 provenance, Sigstore signatures, and full SBOMs.
