history
Project history and usage
cek, the container exploration kit, is a Go CLI for inspecting OCI container image filesystems and layers without running containers.
Project history
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.
Adoption history
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.
How it is used
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.
Why package nerds care
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.
