The majority -of Docker users pull images from Docker's own public registry instance. -Installing Docker gives users this ability. Users with a Docker Hub account can -also push images to this registry. +Docker Registry stores and distributes images centrally. It's where you push images to and pull them from; Docker Registry gives team members the ability to share images and deploy them to testing, staging and production environments. -A subset of Docker users may wish to deploy a Docker Registry Service of their own. For example, users with their own software products and may want to maintain an image store for private, company use. Some companies also maintain a registry instance for release of their software images to the public. +Docker provides a hosted registry as part of [Docker Hub](https://hub.docker.com). Docker Hub is a cloud service that securely manages your images. It features organization accounts, automated builds, and much, much more. -This documentation introduces the registry for users deploying their own instances. You can use this documentation to understand how to configure capabilities into a registry instance or how to write your own custom software to extend the existing service. +Docker Registry is the core technology behind the Docker Hub. You can run your own registry instance if you want to host your images privately. Docker Registry features: + - **Pluggable storage drivers**: Images can be stored in Amazon S3, Microsoft Azure or the local filesystem. + - **Webhook notifications**: When an image is pushed to your registry, webhooks can fire off to launch CI builds, send notifications to IRC, etc. -## Understanding the registry service +To get started with your own Docker Registry, head over to the instructions on how to [deploy a registry](deploying.md). -A registry is, at its heart, a collection of repositories. In turn, a repository is collection of images. Users interact with the registry by pushing images to or pulling images from the registry. The Docker Registry Service includes several optional features that you can configure according to your needs. +## Understanding the registry + +A registry is, at its heart, a collection of repositories.
