## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 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.
