About:
Reg is a command-line interface for interacting with Docker registries. It allows users to list repositories, inspect images, manage tags, and delete artifacts. This tool is particularly useful for registry maintenance and automation tasks where the Docker CLI is unavailable or too heavy.
Key Features:
  • List repositories and tags
  • Inspect image manifests and layers
  • Delete images and garbage collect
  • Cross-platform binary
Use Cases:
  • Auditing registry contents
  • Automated cleanup of old or unused Docker images
Alternatives:
  • skopeo – Skopeo is a more comprehensive tool for copying images between registries, whereas reg focuses on management of a single registry.
  • docker registry v2 API – Direct API calls require custom scripting, while reg provides a convenient CLI wrapper.
