Answer 1

The EC2 Container Registry requires an image Repository to be setup for each image "name" or "namespace/name" you want to publish to the registry.

You can publish any :tags you want in each Repository though (The default limit is 100 tags).

I haven't seen anywhere in the AWS documentation that specifically states the repository -> image name mapping but it's implied by Creating a Repository - Section 6d in the ECR User Guide

The Docker Image spec includes it's definition of a Repository

Repository

A collection of tags grouped under a common prefix (the name component before :). For example, in an image tagged with the name my-app:3.1.4, my-app is the Repository component of the name. A repository name is made up of slash-separated name components, optionally prefixed by a DNS hostname. The hostname must comply with standard DNS rules, but may not contain _ characters. If a hostname is present, it may optionally be followed by a port number in the format :8080. Name components may contain lowercase characters, digits, and separators. A separator is defined as a period, one or two underscores, or one or more dashes. A name component may not start or end with a separator.
