Tell us about your request
We would like to use pull through cache with elastic public registries.

Which service(s) is this request for?
ECR

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
Would like to add a pull-through cache rule for docker.elastic.co public registries to allow a single source for container images (ECR).

Are you currently working around this issue?
We are currently unable to use pull through cache with docker.elastic.co registries as it is not yet supported as an upstream source registry.

Additional context
The Elastic Registry is public and does not require credentials.
