history

Project history and usage

reg is an archived command-line client for inspecting and managing Docker Registry v2 repositories, with listing generation and security-check features.

Project history

reg was developed within the genuinetools collection as a Go command-line client and repository-listing generator for Docker Registry HTTP API V2 services. Its official repository is now archived and read-only.

Adoption history

The supplied metadata records reg packages in Alpine Linux, Homebrew, and Nix, reflecting distribution across container-oriented and Unix package ecosystems.

How it is used

Use `reg` to list registry repositories and tags, inspect manifests and image layers, download or delete images, run supported vulnerability checks, or generate a static registry listing. Connection and authentication values are supplied through command options or environment variables documented by the README.

Why package nerds care

reg packaged several registry-maintenance and inspection workflows into one small executable, including repository and tag listing, manifest and layer inspection, image deletion, static site generation, and security checks.

Related projects

reg operates against Docker Registry v2 and Docker Distribution-compatible services and complements Docker's own command-line tooling.

No Homebrew post-install hook is recorded in formula metadata.
Homebrew bottle metadata is available for 12 platform targets.
Build metadata lists 1 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.

local files

Configuration and credential file locations

These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval.

Credential files

Credential-bearing paths to review before unattended agent runs.
