Docs @ Docker
Welcome to the repo for our documentation. This is the source for the URL served at https://docs.docker.com/.
Feel free to send us pull requests and file issues. Our docs are completely open source and we deeply appreciate contributions from our community!
Providing feedback
We really want your feedback, and we've made it easy. You can edit, rate, or file an issue at the bottom of every page on docs.docker.com.
Please only file issues about the documentation in this repository. One way to think about this is that you should file a bug here if your issue is that you don't see something that should be in the docs, or you see something incorrect or confusing in the docs.
-
If your problem is a general question about how to configure or use Docker, consider asking a question on https://forums.docker.com instead.
-
If you have an idea for a new feature or behavior change in a specific aspect of Docker, or have found a bug in part of Docker, please file that issue in the project's code repository.
Contributing
We value your documentation contributions, and we want to make it as easy as possible to work in this repository. One of the first things to decide is which branch to base your work on. If you get confused, just ask and we will help. If a reviewer realizes you have based your work on the wrong branch, we'll let you know so that you can rebase it.
Note: To contribute code to Docker projects, see the Contribution guidelines.
Overall doc improvements
Most commits will be made against the master
branch. This include:
- Conceptual and task-based information not specific to new features
- Restructuring / rewriting
- Doc bug fixing
- Typos and grammar errors
One quirk of this project is that the master
branch is where the live docs are
published from, so upcoming features can't be documented there. See
Specific new features for a project
for how to document upcoming features. These feature branches will be periodically
merged with master
, so don't worry about fixing typos and documentation bugs
there.
Do you enjoy creating graphics? Good graphics are key to great documentation, and we especially value contributions in this area.
Specific new features for a project
Our docs cover many projects which release at different times. If, and only if,
your pull request relates to a currently unreleased feature of a project, base
your work on that project's vnext
branch. These branches were created by
cloning master
and then importing a project's master
branch's docs into it
(at the time of the migration), in a way that preserved the commit history. When
a project has a release, its vnext
branch will be merged into master
and your
work will be visible on docs.docker.com.
The following vnext
branches currently exist:
-
vnext-engine: docs for upcoming features in the docker/docker project
-
vnext-compose: docs for upcoming features in the docker/compose project
-
vnext-distribution: docs for upcoming features in the docker/distribution project
-
vnext-opensource: docs for upcoming features in the docker/opensource project
-
vnext-swarm: docs for upcoming features in the docker/swarm project
-
vnext-toolbox: docs for upcoming features in the docker/toolbox project
-
vnext-kitematic: docs for upcoming features in the docker/kitematic project
Staging
You have two options:
-
Clone this repo and run our staging container:
git clone https://github.com/docker/docker.github.io.git cd docker.github.io docker-compose up
If you haven't got Docker Compose installed, follow these installation instructions.
The container runs in the background and incrementally rebuilds the site each time a file changes. You can keep your browser open to http://localhost:4000/ and refresh to see your changes. The container runs in the foreground, but you can use
CTRL+C
to get the command prompt back. To stop the container, issue the following command:docker-compose down
-
Use Jekyll directly. Clone this repo, install Ruby 2.3 or higher (required), install the GitHub Pages Ruby gem, then run
jekyll serve
from within the directory.The
jekyll serve
process runs in the foreground, and starts a web server running on http://localhost:4000/ by default. To stop it, useCTRL+C
. You can continue working in a second terminal and Jekyll will rebuild the website incrementally. Refresh the browser to preview your changes. -
Use Github Pages, with or without a local clone. Fork this repo in GitHub, change your fork's repository name to
YOUR_GITHUB_USERNAME.github.io
, and make changes to the Markdown files in yourmaster
branch. Browse to https://<YOUR_GITHUB_USERNAME>.github.io/ to preview the changes.
Important files
/_data/toc.yaml
defines the left-hand navigation for the docs/js/menu.js
defines most of the docs-specific JS such as TOC generation and menu syncing/css/documentation.css
defines the docs-specific style rules/_layouts/docs.html
is the HTML template file, which defines the header and footer, and includes all the JS/CSS that serves the docs content
Relative linking for GitHub viewing
Feel free to link to ../foo.md
so that the docs are readable in GitHub, but keep in mind that Jekyll templating notation
{% such as this %}
will render in raw text and not be processed. In general it's best to assume the docs are being read
directly on docs.docker.com.
Style guide
