Awarded for completing Registry Hygiene at Scale and passing its exam, demonstrating the ability to inventory a container registry estate, design and enforce tagging and immutability, choose and operate a promotion model, scope registry access, apply retention and garbage collection safely, and measure the estate against age, orphan rate, promotion latency and scan freshness.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
