Amazon Elastic Container Registry (ECR)

Amazon 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.

Amazon ECR is integrated with Amazon Elastic Container Service (ECS).

Amazon 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.

Pushing and Pulling Images to ECR

You must first authenticate.

To authenticate Docker to an Amazon ECR registry with get-login-password, run the aws ecr get-login-password command:

aws ecr get-login-password –region us-east-1 | docker login –username AWS –password-stdin aws_account_id.dkr.ecr.us-east-1.amazonaws.com

Tag your image:

docker tag e9ae3c220b23 aws_account_id.dkr.ecr.region.amazonaws.com/my-web-app

Push the image using the docker push command:

docker push aws_account_id.dkr.ecr.region.amazonaws.com/my-web-app

Pull the image using the docker pull command. The image name format should be registry/repository[:tag] to pull by tag, or registry/repository[@digest] to pull by digest.

docker pull aws_account_id.dkr.ecr.region.amazonaws.com/my-web-app:e9ae3c220b23
