2.2.1. Amazon Elastic Container Registry (ECR)

First Principle: Amazon Elastic Container Registry (ECR) provides a fully managed, secure, and scalable registry for Docker container images, simplifying the storage, management, and deployment of containerized applications.

Amazon ECR is a fully managed Docker container registry that integrates seamlessly with Amazon ECS, Amazon EKS, and AWS Lambda. It provides a secure place to store your container images, which are essential for deploying containerized applications.

Key Features of Amazon ECR:

• Fully Managed: No infrastructure to provision or manage.
• Secure: Integrates with IAM for access control and automatically encrypts images at rest.
• Scalable: Automatically scales to meet demand.
• Image Scanning: Scans container images for known Common Vulnerabilities and Exposures (CVEs).
• Lifecycle Policies: Automate the cleanup of old or unused container images.
• Integration: Works seamlessly with Docker CLI, AWS CodeBuild, AWS CodePipeline, ECS, EKS, and Lambda.

Scenario: You've built a microservice application and packaged it as a Docker container image. You need a secure and scalable place to store this image, and also want to scan it for vulnerabilities before deployment.

Reflection Question: How does Amazon ECR, as a fully managed container registry with features like IAM integration for access control and image scanning, simplify the storage, management, and security of your Docker container images throughout the application lifecycle?
