astronomer-registry-cleanup 0.1.2

A command-line tool for managing Docker registry cleanup operations in Astronomer environments

Astronomer Registry Cleanup

Minimal CLI to delete old Docker image tags in Astronomer registries.

Install

pip install astronomer-registry-cleanup

Usage

astronomer-registry-cleanup -r <registry> -p <token> <release_name> -f <prefix> (--keep-n-tags N | --drop-older-tags YYYY-MM-DD) [--dry-run]

Behavior

• Auth: -p is your systemadmin token (username is not required).
• Tags considered: <prefix>-<number> only.
• Safety: never deletes if ≤ 1 tag exists for the prefix.
• Dry-run prints one line per planned deletion: <release_name>:<tag> <digest>.

Examples

# Keep the latest 3 tags for prefix "deploy-" (dry-run)
astronomer-registry-cleanup -r registry.example.com -p <token> my-release -f deploy- --keep-n-tags 3 --dry-run

# Delete everything older than a date for prefix "cli-" (dry-run)
astronomer-registry-cleanup -r registry.example.com -p <token> my-release -f cli- --drop-older-tags 2025-08-01 --dry-run

Notes

• Works against Docker Registry v2 auth flow via Houston.
