# NAME

# 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*.
