NAME
docker-pull - Pull an image or a repository from a registry
SYNOPSIS
docker pull [-a|--all-tags] [--help] NAME[:TAG] | [REGISTRY_HOST[:REGISTRY_PORT]/]NAME[:TAG]
DESCRIPTION
This command pulls down an image or a repository from a registry. If there is more than one image for a repository (e.g., fedora) then all images for that repository name can be pulled down including any tags (see the option -a or --all-tags).
If you do not specify a REGISTRY_HOST, the command uses Docker's public
registry located at registry-1.docker.io by default.
OPTIONS
-a, --all-tags=true|false Download all tagged images in the repository. The default is false.
--help Print usage statement
EXAMPLE
Pull a repository with multiple images with the -a|--all-tags option set to true.
Note that if the image is previously downloaded then the status would be
