1. It does not make sense to run apk many times. 2. Use --no-cache flag to avoid doing update, as per https://github.com/gliderlabs/docker-alpine/blob/master/docs/usage.md#disabling-cache Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
docs-base
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.
Reasons to update this branch
- 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
