Docker - Repository

Card Puncher Data Processing


A repository potentially holds multiple variants (tag) of an image.

Official repository are a carefully curated set of Docker repositories supported by Docker, Inc.

Automated repositories are Automated Builds that allow you to validate the source and content of an image. Automated Builds automate the building and updating of images from GitHub or Bitbucket, directly on Docker Hub. It works by adding a commit hook to your selected GitHub or Bitbucket repository, triggering a build and update when you push a commit.


In the case of the ubuntu image, there is multiple variants covering Ubuntu 10.04, 12.04, 12.10, 13.04, 13.10 and 14.04. Each variant is identified by a tag and you can refer to a tagged image like so:



docker images
REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
