This is the source for docs/docker.github.io:docs-base.

The docs-base Dockerfile includes:

• The GitHub Pages environment (w/Jekyll)
• nginx
• Builds of all previous versions of Docker's documentation

Having this large amount of stuff that stays relatively static in a base image helps keep build times for the docs low as we can use Docker Cloud's caching when running auto-builds out of GitHub.

While you would only see the docs archives by doing so, you can run docs-base locally and peruse by running:

docker run -ti -p 4000:4000 docs/docker.github.io:docs-base

The contents of docs-base will then be viewable in your browser at localhost:4000.

• Changing the nginx configuration
• Publishing a new docs archive, or anything else that stays static between doc builds.
• Updating the GitHub Pages version used in production to a newer release
