## プロジェクトの歴史と使われ方

cek, the container exploration kit, is a Go CLI for inspecting OCI container image filesystems and layers without running containers.

### プロジェクトの歴史

The official repository was created on December 27, 2025. The README positions cek as a command-line utility for browsing files, reading contents, inspecting layer mechanics, listing tags, exporting images, and showing image metadata.

### 採用の歴史

The project is young but has a clear package-manager path through Homebrew and Go installation. The official repository metadata showed more than 300 stars and its first listed GitHub release, v0.2.0, was published on May 16, 2026.

### 使われ方

Users run commands such as `cek ls`, `cek cat`, `cek tags`, `cek export`, `cek tree`, and `cek inspect` against OCI image references. The tool can use local container daemon sockets through `DOCKER_HOST` or pull from remote registries.

### パッケージ好きにとっての重要性

cek is useful to package and container maintainers because it inspects image contents, layers, tags, and metadata without launching a container, which fits CI, registry triage, air-gapped transfer, and image-diff workflows.

### タイムライン

- 2025: The official GitHub repository was created.
- 2026: v0.2.0 was published on GitHub Releases.
- 2026: The official repository metadata recorded active development into July.

### Related projects
