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 Print usage statement

EXAMPLE

Pull a repository with multiple images

Note that if the image is previously downloaded then the status would be

'Status: Image is up to date for fedora'
