Originally posted by yashid-mohamed December 11, 2025 I’d like to request a new webhook event type that triggers specifically when a tag is created (without requiring the artifact itself to be pushed again).
Problem
When performing tag promotion (e.g., promoting an existing digest from 0.403.0 → 0.403.0-prod) using the Harbor API or UI, Harbor currently does not emit any webhook for this action.
This creates a gap for CI/CD pipelines and downstream automation tools that rely on webhook notifications to react to new tags. Since no new artifact is pushed and no scan/build occurs, none of the existing webhook types fire.
Use Case
Many promotion workflows rely on copying or creating tags inside Harbor (to preserve digest immutability and avoid re-pushing images). Examples:
- Promotion from dev → prod
- Tagging releases in automation pipelines
- Triggering deployments based on tag creation
Without a webhook event for tag creation, external systems must continuously poll Harbor, which is inefficient.
