Why?

The idea came from the need to download images from the geographically closest docker registry. We operate our Kubernetes cluster in Sydney/Australia but use CircleCI operating in the US. Because AWS ECR doesn't provide a common endpoint with geographically distributed backend we push our images to both locations. Within our Makefile we can use cloudping to identify if images should be pulled from the US or Sydney.
