This is using AWS ECR as a proxy to docker hub, correct? Edit: Not exactly, it looks like ECR mirrors docker-library (a.k.a. images on docker hub no preceded by a namespace), not all of Docker Hub. Edit 2: I think the example you give there is misleading, as Ubuntu has its own namespace in ECR. If you want to highlight that ECR mirrors docker-library, a more appropriate example might be `docker pull public.ecr.aws/docker/library/ubuntu`.
