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 is a regional service, which means that each AWS Region has its own ECR registry.
ECR offers a number of features to help you manage your container images securely, including:
Private repositories: ECR supports private repositories, which means that only authorized users can access your images.
Image scanning: ECR can scan your images for vulnerabilities. This helps you to identify and fix security vulnerabilities in your images before they are deployed.
Lifecycle policies: ECR can be configured to automatically delete unused images. This helps you to save storage space and costs.
Integrated with Docker: ECR integrates with the Docker CLI, so that you can push and pull images from your ECR repositories using the same commands that you would use for local repositories.
Benefits of Using AWS ECR
Here are some of the benefits of using AWS ECR:
Secure storage: ECR stores your images in Amazon S3, which is a highly secure object storage service.
Scalable: ECR can scale to meet the needs of your application.
Cost-effective: ECR is a pay-as-you-go service, so you only pay for the storage and bandwidth that you use.
Easy to use: ECR is easy to use and integrate with your existing Docker workflows.
