Pull and push container images from and to AWS ECR repositories via Docker CLI

To use the regular Docker CLI with Amazon Elastic Container Registry (Amazon ECR), you have to acquire specific login credentials for it first. Assuming you already got basic AWS credentials, run the following to pass those on to Docker. Just note that, below, AWS_ACCOUNT_ID refers to the repository owner, which may not be your own AWS account.

aws ecr get-login-password --region <AWS_REGION> | docker login -u AWS --password-stdin https://<AWS_ACCOUNT_ID>.dkr.ecr.<AWS_REGION>.amazonaws.com

# Example for the official Sagemaker ECR repository
aws ecr get-login-password --region us-east-1 | docker login -u AWS --password-stdin https://683313688378.dkr.ecr.us-east-1.amazonaws.com

Once you’re logged in, list all available container images in a repository with the following:

aws ecr describe-images --region <AWS_REGION> --registry-id <AWS_ACCOUNT_ID> --repository-name <REPOSITORY_NAME>

# Example for the official Sagemaker ECR repository
aws ecr describe-images --region us-east-1 --registry-id 683313688378 --repository-name sagemaker-scikit-learn
