FAQPage Schema
How do I automatically remove old container images from DigitalOcean registries?▼

Container image cleanup removes obsolete tags from DigitalOcean registries based on retention policies, keeping storage costs low. This Skill applies per-repository rules—preserving :latest while retaining 10 tags for staging and 30 for production—and reports estimated storage savings.

Can I preview what will be deleted before running registry cleanup?▼

Yes, the Skill runs in dry-run mode by default, showing which tags would be deleted and their storage impact without making changes. Add --confirm to execute actual deletions after reviewing the preview.

What are the prerequisites for cleaning up DigitalOcean container registries?▼

You need curl and jq installed, a DigitalOcean API token stored in user secrets, and access to your container registries. The Skill validates these dependencies before listing and removing tags.

Does registry cleanup work with both staging and production environments?▼

Yes, the Skill applies different retention policies per environment: staging keeps 10 tags while production keeps 30, ensuring safer rollback capacity in production while aggressively cleaning staging images.

How often should I run container image cleanup to manage registry storage?▼

The Skill supports weekly dry-run scheduling by default. Run manually with --confirm when ready to delete, or automate weekly executions to maintain consistent storage savings across your DigitalOcean repositories.
