Amazon Elastic Container Registry

What is Amazon Elastic Container Registry?

Amazon Elastic Container Registry (ECR) is a managed service that allows users to store, manage, share, and deploy container images and artifacts. It is mainly integrated with Amazon Elastic Container Service (ECS), for simplifying the production workflow.

Features:

● It stores both the containers which are created, and any container software bought through AWS Marketplace.

● It is integrated with Amazon Elastic Container Service (ECS), Amazon Elastic Kubernetes Service (EKS), and AWS Lambda, and AWS Fargate for easy deployments.

● AWS Identity and Access Management (IAM) enables resource-level control of each repository within ECR.

● It supports public and private container image repositories. It allows sharing container applications privately within the organization or publicly for anyone to download.

● A separate portal called Amazon ECR Public Gallery, helps to access all public repositories hosted on Amazon ECR Public.

● It stores the container images in Amazon S3 because S3 provides 99.999999999% (11 9’s) of data durability.

● It allows cross-region and cross-account replication of the data for high availability applications

● Encryption can be done via HTTPS while transferring container images.

Images are also encrypted at rest using Amazon S3 server-side encryption or by using customer keys managed by AWS KMS.

● It is integrated with continuous integration and continuous delivery and also with third-party developer tools.

● Lifecycle policies are used to manage the lifecycle of the images.

Pricing details:

● Using AWS Free Tier, new customers get 500 MB-month of storage for one year for private repositories and 50 GB-month of free storage for public repositories.
