1.1 Notable Updates

Docker allows you to create and distribute applications across Oracle Linux systems and other operating systems that support Docker. Docker consists of the Docker Engine, which packages and runs the applications, and the Docker Hub, which shares the applications in a Software-as-a-Service (SaaS) cloud.

The Docker Engine is designed primarily to run single applications in a similar manner to LXC application containers that provide a degree of isolation from other processes running on a system.

The Docker Hub hosts applications as Docker images and provides services that allow you to create and manage a Docker environment. You must register with the Docker Hub Registry to be able to access its resources and services.


The Docker Hub is owned and maintained by Docker, Inc. Oracle makes Docker images available on the Docker Hub that you can download and use with the Docker Engine. Oracle does not have any control otherwise over the content of the Docker Hub Registry site or its repositories.

Oracle provides access to the Oracle Container Registry for customers that have a Single Sign-On account at Oracle. The Oracle Container Registry contains Docker images for licensed commercial Oracle software products that you may use in your enterprise. Images may also be used for development and testing purposes. The license covers both production and non-production use. The Oracle Container Registry provides a web interface where customers are able to select Oracle Docker images and agree to terms of use before pulling the images using the standard Docker client software. More information on this service is provided in Section 5.1, “Using the Oracle Container Registry”.
