Both Artifactory and Docker use the term "repository", but each uses it in a different way.
A Docker repository is a hosted collection of tagged images that, together, create the file system for a container
A Docker registry is a host that stores Docker repositories
An Artifactory repository is a hosted collection of Docker repositories, effectively, a Docker registry in every way, and one that you can access transparently with the Docker client.
Since Artifactory places no limitation on the number of repositories you may create, you can manage any number of Docker registries in Artifactory.
