| Term | Description |
|---|---|
| Registry | An ECR registry is provided to each AWS account, we can create image repositories in our registry and store images in them. |
| Repository | An ECR image repository contains our Docker images. |
| Repository policy | We can control access to our repositories and the images within them with repository policies. |
| Authorization token | Our Docker client must authenticate to Amazon ECR registries as an AWS user before it can push and pull images. The AWS CLI get-login command provides us with authentication credentials to pass to Docker. |
| Image | We can push and pull container images to our repositories. We can use these images locally on your development system, or we can use them in Amazon ECS task definitions. |
- Amazon ECR is an alternative to Docker Hub.
