# Docker Registry 2.0
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
To get started with your own Docker Registry, head over to the instructions on how to [deploy a registry](deploying.md).
|
|
|
|
## Understanding the registry
|
|
|
|
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 includes several
|
|
optional features that you can configure according to your needs.
|
|
|
|
|
|
|
|
The architecture supports a configurable storage backend. You can store images
|
|
on a file system or on a service such as Amazon S3 or Microsoft Azure. The
|
|
default storage system is the local disk; this is suitable for development or
|
|
some small deployments.
|
|
|
|
Securing access to images is a concern for even the simplest deployment. The
|
|
registry service supports transport layer security (TLS) natively. You must
|
|
configure it in your instance to make use of it. You can also use a proxy server
|
|
such as Nginx and basic authentication to extend the security of a deployment.
|
|
|
|
The registry repository includes reference implementations for additional
|
|
authentication and authorization support. Only very large or public registry
|
|
deployments are expected to extend the registry in this way.
|
|
|
|
Docker Registry architecture includes a robust notification system. This system
|
|
sends webhook notifications in response to registry activity. The registry also
|
|
includes features for both logging and reporting as well. Reporting is useful
|
|
for large installations that want to collect metrics. Currently, the feature
|
|
supports both New Relic and Bugsnag.
|
|
|
|
