Overview

Pull an image or a repository from a registry and place it into the local registry:

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.

Example

docker pull registry.access.redhat.com/openshift3/jenkins-2-rhel7
Using default tag: latest
