Implementing a Self-hosted Docker Registry

by Wes Higbee

At some point, you will outgrow storing custom images on Docker Hub. This course prepares you to deploy your own self-hosted registry.

What you'll learn

What would Docker be without Docker Hub? If it were not for images, you would never have heard of Docker, and that's because simplifying image distribution is what made Docker exponentially useful. Initially the images on Docker Hub suffice, but at some point, as you begin to build your own images, you'll outgrow storing them on Docker Hub for a variety of reasons.

In this course, Implementing a Self-hosted Docker Registry, we will dissect deploying your own registry in the following scenarios.

First, you will learn to take total control of a registry, perhaps as a matter of compliance, and learn to distribute sensitive images privately.
Next, you will see how to co-locate a registry for performance reasons, to save bandwidth, or to mirror Docker Hub images to a local registry cache.
Then, you will explore the internal workings of a registry and gain flexibility in securing your registry.
Finally, you will be able to standardize application packaging and distribution within your organization using Docker images, to reap the same benefits that Docker Hub brought to open-source public applications.

By the end of this course, you'll be well prepared to deploy your own self-hosted registry.
