Accessing registries

A Docker registry is accessed via the Docker daemon service using a Docker client. The Docker command line uses a RESTful API to request process execution from the daemon. Most of these commands are translated into HTTP requests and may be transmitted using curl.

The process of using Docker registries is shown in the following section.

A developer can create a Docker image and put it into a private or public registry. Once the image is uploaded, it can be immediately used to run containers or build other images.
