Chapter 5 Docker Registry

A Docker registry is a store of Docker images. A Docker image is a read-only template, which is used to create a Docker container. A Docker registry is used to store Docker images, which are used to deploy containers as required.

The default Docker registry is hosted at https://hub.docker.com. Oracle hosts its own Docker registry for Oracle software that requires users to accept Oracle Standard Terms and Restrictions prior to deployment. This registry is located at https://container-registry.oracle.com.

Enterprise environments may consider setting up a local Docker registry. This provides the opportunity to convert customized containers into images that can be committed into a local registry, to be used for future container deployment, reducing the amount of customized configuration that may need to be performed for mass deployments. A local registry can also cache and host images pulled from an upstream registry. This can reduce network overhead and latency when deploying matching containers across a spread of local systems.
