I'm trying to pull the pre-built docker images for SageMaker. I am able to successfully docker login to ECR (my AWS credentials). When I try to pull the image I get the standard no basic auth credentials.
Maybe I'm misunderstanding... I assumed those ECR URLs were public.
$(aws ecr get-login --region us-west-2 --no-include-email)
docker pull 246618743249.dkr.ecr.us-west-2.amazonaws.com/sagemaker-scikit-learn
Could you show your ECR login command and pull command in the question?
For SageMaker pre-built image 520713654638.dkr.ecr.us-west-2.amazonaws.com/sagemaker-mxnet:1.3.0-cpu-py3
What I do is:
$(aws ecr get-login --no-include-email --registry-ids 520713654638 --region us-west-2)
docker pull 520713654638.dkr.ecr.us-west-2.amazonaws.com/sagemaker-mxnet:1.3.0-cpu-py3
These images are public readable so you can pull them from any AWS account. I guess the reason you failed is that you did not specify --registry-ids in your login. But it's better if you can provide your scripts for others to identify what's wrong.
