history

Project history and usage

diffoci is a command-line comparison tool for Docker and OCI container images, aimed at finding the practical differences between two image artifacts in reproducible-builds work.

Project history

The project lives under the reproducible-containers organization and frames itself as a diff tool for Docker and OCI images. Its README presents strict comparison as the baseline and semantic comparison as the more useful mode for image reproducibility checks.

Adoption history

The official README documents binary releases for Linux and macOS, installation through mise, and source installation with Go, which places diffoci in the familiar package-manager and single-binary CLI lane for container tooling.

How it is used

Typical use compares two image references with `diffoci diff IMAGE0 IMAGE1`; the README recommends `--semantic` when timestamp, layer ordering, build history, or image-name annotation noise would make strict output too noisy. It can also compare local Docker or Podman images with `docker://` and `podman://` prefixes and can dump differing files to a report directory.

Why package nerds care

For package maintainers and reproducible-builds people, diffoci fills the gap between byte-level archive comparison and the layered, metadata-heavy world of OCI images. It is useful when the artifact being packaged is not a tarball or binary but a container image with registry, platform, and layer semantics.

Timeline

  • 2023: README examples focus on comparing Alpine and Docker Hub images in reproducibility investigations.
  • 2020s: Project distributed as a Go CLI with Linux and macOS binary releases.

Related projects

  • diffoci is adjacent to diffoscope for deep artifact comparison, but specializes in Docker and OCI image layout, containerd, Docker, Podman, and registry workflows.
