Docker Tags

CLI tool to list tags for Docker images with sensible sorting.

Features

• Works with Docker Hub and other registries, compliant with OCI Distribution Specification.
• Sorts semantic versions with newest first and falls back to alphabetical for non-semver tags.
• Supports authentication via Docker credentials (~/.docker/config.json).
• Can filter tags by regex (-f flag) and limit the number of tags shown (-n flag).

Basic Usage (CLI)

• docker-tags [<registry>/][<namespace>/]<image> — list tags for an image (e.g., docker-tags alpine).
• docker-tags -r [<registry>/][<namespace>/]<image> — same, but reverse the order (e.g., docker-tags -r quay.io/prometheus/prometheus).
