The document discusses Docker registry, which allows storing private Docker images. It demonstrates how to start a local Docker registry container, tag and push a local image to the private registry, and then pull it back. The registry can be configured using a config.yml file to specify storage settings and enable HTTPS. Docker Compose is also shown as another way to run the registry container with volumes and ports mapped.
