CI ANCC

ecrspectre — Container registry waste auditor for ECR and Artifact Registry. Part of SpectreHub.

What it is

  • Scans AWS ECR and GCP Artifact Registry for stale, untagged, and bloated images
  • Checks pull timestamps, tag status, image size, and lifecycle policies
  • Estimates monthly storage cost per finding
  • Surfaces vulnerability scan data from ECR's built-in scanner
  • Generates remediation plans: ECR lifecycle policies and dry-run delete scripts (read-only)
  • Outputs text, JSON, SARIF, SpectreHub, policy, and delete-script formats

What it is NOT

  • Not a real-time monitor — point-in-time scanner
  • Not a remediation tool — reports only, never deletes images
  • Not a security scanner — surfaces existing ECR scan data
  • Not a CI image builder — audits what exists
