# Docker Documentation
|
|
|
|
The source for Docker documentation is in this directory. Our
|
|
documentation uses extended Markdown, as implemented by
|
|
[MkDocs](http://mkdocs.org). The current release of the Docker documentation
|
|
resides on [https://docs.docker.com](https://docs.docker.com).
|
|
|
|
## Understanding the documentation branches and processes
|
|
|
|
Docker has two primary branches for documentation:
|
|
|
|
| Branch | Description | URL (published via commit-hook) |
|
|
|----------|--------------------------------|------------------------------------------------------------------------------|
|
|
| `docs` | Official release documentation | [https://docs.docker.com](https://docs.docker.com) |
|
|
| `master` | Merged but unreleased development work | [http://docs.master.dockerproject.org](http://docs.master.dockerproject.org) |
|
|
|
|
Additions and updates to upcoming releases are made in a feature branch off of
|
|
the `master` branch. The Docker maintainers also support a `docs` branch that
|
|
contains the last release of documentation.
|
|
|
|
After a release, documentation updates are continually merged into `master` as
|
|
they occur. This work includes new documentation for forthcoming features, bug
|
|
fixes, and other updates. Docker's CI system automatically builds and updates
|
|
the `master` documentation after each merge and posts it to
|
|
[http://docs.master.dockerproject.org](http://docs.master.dockerproject.org).
|
|
|
|
Periodically, the Docker maintainers update `docs.docker.com` between official
|
|
releases of Docker. They do this by cherry-picking commits from `master`,
|
|
merging them into `docs`, and then publishing the result.
|
|
|
|
In the rare case where a change is not forward-compatible, changes may be made
|
|
on other branches by special arrangement with the Docker maintainers.
|
|
|
|
### Quickstart for documentation contributors
|
|
|
|
If you are a new or beginner contributor, we encourage you to read through the
|
|
[our detailed contributors
|
|
guide](who-written-for.md). The guide explains in
|
|
detail, with examples, how to contribute. If you are an experienced contributor
|
|
this quickstart should be enough to get you started.
|
|
|
|
The following is the essential workflow for contributing to the documentation:
|
|
|
|
1. Fork the `docker/docker` repository.
|
|
|
|
2. Clone the repository to your local machine.
|
|
|
|
3. Select an issue from `docker/docker` to work on or submit a proposal of your
|
|
own.
|
|
|
|
4. Create a feature branch from `master` in which to work.
|
|
|
|
By basing from `master` your work is automatically included in the next
|
|
release. It also allows docs maintainers to easily cherry-pick your changes
|
|
into the `docs` release branch.
|
|
|
|
4. Modify existing or add new `.md` files to the `docs` directory.
|
|
|
|
5. As you work, build the documentation site locally to see your changes.
|
|
|
|
The `docker/docker` repository contains a `Dockerfile` and a `Makefile`.
|
|
Together, these create a development environment in which you can build and
|
|
run a container running the Docker documentation website. To build the
|
|
documentation site, enter `make docs` at the root of your `docker/docker`
|
|
fork:
|
|
|
|
$ make docs
|
|
.... (lots of output) ....
|
|
docker run --rm -it -e AWS_S3_BUCKET -p 8000:8000 "docker-docs:master" mkdocs serve
|
|
Running at: http://0.0.0.0:8000/
|
|
Live reload enabled.
|
|
Hold ctrl+c to quit.
|
|
|
|
|
|
The build creates an image containing all the required tools, adds the local
|
|
`docs/` directory and generates the HTML files. Then, it runs a Docker
|
|
container with this image.
|
|
|
|
The container exposes port 8000 on the localhost so that you can connect and
|
|
see your changes. If you use Docker Machine, the `docker-machine ip
|
|
<machine-name>` command gives you the address of your server.
|
|
|
|
6. Check your writing for style and mechanical errors.
|
|
|
|
Use our [documentation style
|
|
guide](doc-style.md) to check style. There are
|
|
several [good grammar and spelling online
|
|
checkers](http://www.hemingwayapp.com/) that can check your writing
|
|
mechanics.
|
|
|
|
7. Squash your commits on your branch.
|
|
|
|
8. Make a pull request from your fork back to Docker's `master` branch.
|
|
|
|
9. Work with the reviewers until your change is approved and merged.
|
|
|
|
### Debugging and testing
|
|
|
|
If you have any issues you need to debug, you can use `make docs-shell` and then
|
|
run `mkdocs serve`. You can use `make docs-test` to generate a report of missing
|
|
links that are referenced in the documentation—there should be none.
|
|
|
|
## Style guide
|
|
|
|
If you have questions about how to write for Docker's documentation, please see
|
|
the [style guide](doc-style.md). The style guide provides
|
|
guidance about grammar, syntax, formatting, styling, language, or tone. If
|
|
something isn't clear in the guide, please submit an issue to let us know or
|
|
submit a pull request to help us improve it.
|
|
|
|
|
|
## Publishing documentation (for Docker maintainers)
|
|
|
|
To publish Docker's documentation you need to have Docker up and running on your
|
|
machine. You'll also need a `docs/awsconfig` file containing the settings you
|
|
need to access the AWS bucket you'll be deploying to.
|
|
|
|
The process for publishing is to build first to an AWS bucket, verify the build,
|
|
and then publish the final release.
|
|
|
|
1. Have Docker installed and running on your machine.
|
|
|
|
2. Ask the core maintainers for the `awsconfig` file.
|
|
|
|
3. Copy the `awsconfig` file to the `docs/` directory.
|
|
|
|
The `awsconfig` file contains the profiles of the S3 buckets for our
|
|
documentation sites. (If needed, the release script creates an S3 bucket and
|
|
pushes the files to it.) Each profile has this format:
|
|
|
|
[profile dowideit-docs]
|
|
aws_access_key_id = IHOIUAHSIDH234rwf....
|
|
aws_secret_access_key = OIUYSADJHLKUHQWIUHE......
|
|
region = ap-southeast-2
|
|
|
|
The `profile` name must be the same as the name of the bucket you are
|
|
deploying to.
|
|
|
|
4. Call the `make` from the `docker` directory.
|
|
|
|
$ make AWS_S3_BUCKET=dowideit-docs docs-release
|
|
|
|
This publishes _only_ to the `http://bucket-url/v1.2/` version of the
|
|
documentation.
|
|
|
|
5. If you're publishing the current release's documentation, you need to also
|
|
update the root docs pages by running
|
|
|
|
$ make AWS_S3_BUCKET=dowideit-docs BUILD_ROOT=yes docs-release
|
|
|
|
### Errors publishing using a Docker Machine VM
|
|
|
|
Sometimes, in a Windows or Mac environment, the publishing procedure returns this
|
|
error:
|
|
|
|
Post http:///var/run/docker.sock/build?rm=1&t=docker-docs%3Apost-1.2.0-docs_update-2:
|
|
dial unix /var/run/docker.sock: no such file or directory.
|
|
|
|
If this happens, set the Docker host. Run the following command to get the
|
|
variables in your shell:
|
|
|
|
docker-machine env <machine-name>
|
|
|
|
Then, set your environment accordingly.
|
|
|
|
## Cherry-picking documentation changes to update an existing release.
|
|
|
|
Whenever the core team makes a release, they publish the documentation based on
|
|
the `release` branch. At that time, the `release` branch is copied into the
|
|
`docs` branch. The documentation team makes updates between Docker releases by
|
|
cherry-picking changes from `master` into any of the documentation branches.
|
|
Typically, we cherry-pick into the `docs` branch.
|
|
|
|
For example, to update the current release's docs, do the following:
|
|
|
|
1. Go to your `docker/docker` fork and get the latest from master.
|
|
|
|
$ git fetch upstream
|
|
|
|
2. Checkout a new branch based on `upstream/docs`.
|
|
|
|
You should give your new branch a descriptive name.
|
|
|
|
$ git checkout -b post-1.2.0-docs-update-1 upstream/docs
|
|
|
|
3. In a browser window, open [https://github.com/docker/docker/commits/master].
|
|
|
|
4. Locate the merges you want to publish.
|
|
|
|
You should only cherry-pick individual commits; do not cherry-pick merge
|
|
commits. To minimize merge conflicts, start with the oldest commit and work
|
|
your way forward in time.
|
|
|
|
5. Copy the commit SHA from GitHub.
|
|
|
|
6. Cherry-pick the commit.
|
|
|
|
$ git cherry-pick -x fe845c4
|
|
|
|
7. Repeat until you have cherry-picked everything you want to merge.
|
|
|
|
8. Push your changes to your fork.
|
|
|
|
$ git push origin post-1.2.0-docs-update-1
|
|
|
|
9. Make a pull request to merge into the `docs` branch.
|
|
|
|
Do __NOT__ merge into `master`.
|
|
|
|
10. Have maintainers review your pull request.
|
|
|
|
11. Once the PR has the needed "LGTMs", merge it on GitHub.
|
|
|
|
12. Return to your local fork and make sure you are still on the `docs` branch.
|
|
|
|
$ git checkout docs
|
|
|
|
13. Fetch your merged pull request from `docs`.
|
|
|
|
$ git fetch upstream/docs
|
|
|
|
14. Ensure your branch is clean and set to the latest.
|
|
|
|
$ git reset --hard upstream/docs
|
|
|
|
15. Copy the `awsconfig` file into the `docs` directory.
|
|
|
|
16. Make the beta documentation
|
|
|
|
$ make AWS_S3_BUCKET=beta-docs.docker.io BUILD_ROOT=yes docs-release
|
|
|
|
17. Open [the beta
|
|
website](http://beta-docs.docker.io.s3-website-us-west-2.amazonaws.com/) site
|
|
and make sure what you published is correct.
|
|
|
|
19. When you're happy with your content, publish the docs to our live site:
|
|
|
|
$ make AWS_S3_BUCKET=docs.docker.com BUILD_ROOT=yes
|
|
DISTRIBUTION_ID=C2K6......FL2F docs-release
|
|
|
|
20. Test the uncached version of the live docs at [http://docs.docker.com.s3-website-us-east-1.amazonaws.com/]
|
|
|
|
|
|
### Caching and the docs
|
|
|
|
New docs do not appear live on the site until the cache (a complex, distributed
|
|
CDN system) is flushed. The `make docs-release` command flushes the cache _if_
|
|
the `DISTRIBUTION_ID` is set to the Cloudfront distribution ID. The cache flush
|
|
can take at least 15 minutes to run and you can check its progress with the CDN
|
|
Cloudfront Purge Tool Chrome app.
|
|
|
|
## Removing files from the docs.docker.com site
|
|
|
|
Sometimes it becomes necessary to remove files from the historical published documentation.
|
|
The most reliable way to do this is to do it directly using `aws s3` commands running in a
|
|
docs container:
|
|
|
|
Start the docs container like `make docs-shell`, but bind mount in your `awsconfig`:
|
|
|
|
```
|
|
docker run --rm -it -v $(CURDIR)/docs/awsconfig:/docs/awsconfig docker-docs:master bash
|
|
```
|
|
|
|
and then the following example shows deleting 2 documents from s3, and then requesting the
|
|
CloudFlare cache to invalidate them:
|
|
|
|
|
|
```
|
|
export BUCKET BUCKET=docs.docker.com
|
|
export AWS_CONFIG_FILE=$(pwd)/awsconfig
|
|
aws s3 --profile $BUCKET ls s3://$BUCKET
|
|
aws s3 --profile $BUCKET rm s3://$BUCKET/v1.0/reference/api/docker_io_oauth_api/index.html
|
|
aws s3 --profile $BUCKET rm s3://$BUCKET/v1.1/reference/api/docker_io_oauth_api/index.html
|
|
|
|
aws configure set preview.cloudfront true
|
|
export DISTRIBUTION_ID=YUTIYUTIUTIUYTIUT
|
|
aws cloudfront create-invalidation --profile docs.docker.com --distribution-id $DISTRIBUTION_ID --invalidation-batch '{"Paths":{"Quantity":1, "Items":["/v1.0/reference/api/docker_io_oauth_api/"]},"CallerReference":"6Mar2015sventest1"}'
|
|
aws cloudfront create-invalidation --profile docs.docker.com --distribution-id $DISTRIBUTION_ID --invalidation-batch '{"Paths":{"Quantity":1, "Items":["/v1.1/reference/api/docker_io_oauth_api/"]},"CallerReference":"6Mar2015sventest1"}'
|
|
```
|
|
|
|
