AWS › Elastic Container Registry (ECR)
How should an organization design a comprehensive container image governance strategy across multiple ECR repositories, teams, and AWS accounts?
AdvancedAnswer
A comprehensive governance strategy typically centralizes shared base images in a dedicated shared services account with carefully scoped cross account repository policies, enforces mandatory image scanning with defined vulnerability severity thresholds that block deployment of non compliant images, applies consistent lifecycle policies to control storage costs across all repositories, and establishes clear tagging conventions, such as immutable tags for production releases, ensuring consistency, security, and cost control as the number of teams and repositories grows across the organization.
