Docker
A Docker registry is a repository for Docker images. Docker clients connect to registries to download (docker pull) images for use or upload (docker push) images. A Docker Registry HTTP API is available to facilitate distribution of images to the docker engine[3] with support for image verification, resumable push and pull operations and layer deduplication.
Docker Registries can be public or private. Two main public registries are Docker Hub and Docker Cloud. Docker Hub is the default registry where Docker looks for images. Docker registries also allow the creation of notifications based on events.[4]
AWS ECR
AWS ECR[5] is a managed container registry service from AWS available since December 2015[6] with tagging (see docker tag) support from December 2018[7]
