Overview
Pull an image or a repository from a registry and place it into the local registry. By default the command pulls from Docker Hub.
docker pull <name>[:<tag>]
The command pulls each layer separately, and it will only pull the layers that do not exist in the local repository.
The command accepts an image name or a repository name.
Example

Pull from a Different Registry
By default, docker pull pulls images from Docker Hub, but an image can be pulled form a different registry by specifying the registry path as prefix of the image name.
