# NAME
docker-pull - Pull an image or a repository from a registry

# SYNOPSIS
**docker pull**
[**-a**|**--all-tags**[=*false*]]
[**--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 are pulled down including any 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**

# EXAMPLE

# 'Status: Image is up to date for fedora'
