ECR (Elastic Container Registry) – AWS’s container image registry.
Amazon Elastic Container Registry is a fully managed container registry service for storing, managing, and deploying container images. It features integration with AWS IAM for access control, lifecycle policies for image management, and cross-region replication. ECR provides vulnerability scanning for container images, supports image signing for security, and enables pull through cache for public registries. The service includes immutable image tags, image scanning on push, and detailed API actions through CloudTrail. It supports both private and public repositories with different permission models.
