A private repository gives you total control over who is able to push and pull images. This improves security by limiting access and keeping a full audit log. With proper configuration of caching and load balancing, a private repository can also speed up deployments.
In this recipe, you will learn how to configure Mesos to use a custom Docker repository with optional authentication. This will enable you to host a private repository inside your organization.
You need to have Docker support enabled; see the Configuring Docker image support for Mesos containerizer and Using Docker containerizer recipes to get more information.
