Registry in Docker is a type of storage that holds Docker images, which can then be renamed with different tags. Artifactory is a secure, private Docker registry with fine-grained access control. With Artifactory, you can create multiple repositories and have, for example, one for each team in your organization and/or each development phase of a project. You can assign access and use permissions. And via integration with JFrog Xray, you can even scan images for vulnerabilities and policy violations.
