Lesson in the AWS Roadmap for Beginners · Stage 15: ECR

What is ECR?

AWS Elastic Container Registry (ECR) is a fully-managed Docker container registry that makes it easy for developers to store, manage, and deploy Docker container images. ECR eliminates the need to operate your own container repositories or worry about scaling the underlying infrastructure. ECR hosts your images in a highly available and scalable architecture, allowing you to reliably deploy containers for your applications. Integration with AWS Identity and Access Management (IAM) provides resource-level control of each repository.
