How to pull a single image from any docker repository?

The docker repositories contains multiple images. Is it possible to just pull the specific image from Repository.

When I use: 

docker pull  ubuntu

It pulls down around 8-10 different versions of ubuntu.

Solution

  • If there's a specific image that's tagged, you could use the --tag= (or -t) operator to pull the specific image you're looking for. There's a shorthand form for the command as well, which uses just a colon between the image name and the tag.

    So if you want the version of ubuntu that's tagged as quantal, you could use:

    docker pull ubuntu:quantal

    The longer forms would be:

    docker pull --tag="quantal" ubuntu
docker pull --t quantal ubuntu

    This will still pull the historical layers used to build the final image, but will be a smaller subset than all of the layers for ubuntu.

    [Updated to include Ben's note on shorthand from below. Thanks!]
