Amazon ECR (Elastic Container Registry) is a fully managed Docker container registry that makes it easy to store, manage, and deploy Docker container images. ECR is integrated with ECS and EKS for seamless container orchestration.

Repositories

ECR stores your container images in repositories. Each repository can contain multiple image versions (tags). ECR supports both public and private repositories. Private repositories are encrypted by default and can be accessed via IAM policies.

Lifecycle Policies

ECR provides lifecycle policies to automatically clean up old or unused images. You can set rules based on image age, image count, or tag patterns. This helps reduce storage costs by removing unnecessary images.

Image Scanning

ECR supports image scanning for vulnerabilities. You can enable automatic scanning on push, or scan images manually. ECR uses AWS security scanning to identify security vulnerabilities in your container images.
