history
Project history and usage
chunkah is a CoreOS OCI image tool that turns a flat root filesystem or existing image into content-based layers intended to improve layer reuse.
Project history
The GitHub repository was created in December 2025. The README explains chunkah as a post-processing step for images whose Dockerfile-derived layers do not match reusable content boundaries.
Adoption history
The upstream README presents container-image use through quay.io/coreos/chunkah as the primary path, with cargo install and Fedora packaging as additional options. The batch input records Homebrew and DNF packaging.
How it is used
Users can split an existing image or split an image at build time with Podman and Buildah. The README also documents Docker image-mount usage, SOURCE_DATE_EPOCH support, cosign verification, xattr-based component hints, output formats, max-layer tuning, pruning, and bootc-image compatibility.
Why package nerds care
chunkah is interesting to container and distro package people because it maps package or component boundaries back onto OCI layers after the image has been built. That makes package churn, client pulls, and shared storage the focus rather than the textual Dockerfile step history.
