A maintainer's guide to releasing Docker

So you're in charge of a Docker release? Cool. Here's what to do.

If your experience deviates from this document, please document the changes to keep it up-to-date.

1. Pull from master and create a release branch

git checkout master
git pull
git checkout -b bump_$VERSION

2. Update CHANGELOG.md

You can run this command for reference:

LAST_VERSION=$(git tag | grep -E "v[0-9\.]+$" | sort -nr | head -n 1)
git log $LAST_VERSION..HEAD

Each change should be formatted as BULLET CATEGORY: DESCRIPTION

  • BULLET is either -, + or *, to indicate a bugfix, new feature or upgrade, respectively.

  • CATEGORY should describe which part of the project is affected. Valid categories are:

    • Builder
    • Documentation
    • Hack
    • Packaging
    • Remote API
    • Runtime
  • DESCRIPTION: a concise description of the change that is relevant to the end-user, using the present tense. Changes should be described in terms of how they affect the user, for example "new feature X which allows Y", "fixed bug which caused X", "increased performance of Y".

EXAMPLES:

+ Builder: 'docker build -t FOO' applies the tag FOO to the newly built
  container.
* Runtime: improve detection of kernel version
- Remote API: fix a bug in the optional unix socket transport

3. Change the contents of the VERSION file

4. Run all tests

FIXME

5. Test the docs

Make sure that your tree includes documentation for any modified or new features, syntax or semantic changes. Instructions for building the docs are in docs/README.md

6. Commit and create a pull request to the "release" branch

git add CHANGELOG.md
git commit -m "Bump version to $VERSION"
git push origin bump_$VERSION

7. Get 2 other maintainers to validate the pull request

8. Merge the pull request and apply tags

git checkout release
git merge bump_$VERSION
git tag -a v$VERSION # Don't forget the v!
git tag -f -a latest
git push
git push --tags

Merging the pull request to the release branch will automatically update the documentation on the "latest" revision of the docs. You should see the updated docs 5-10 minutes after the merge. The docs will appear on http://docs.docker.io/. For more information about documentation releases, see docs/README.md

9. Publish binaries

To run this you will need access to the release credentials. Get them from the infrastructure maintainers.

docker build -t docker .
docker run  \
	-e AWS_S3_BUCKET=get-nightly.docker.io \
	-e AWS_ACCESS_KEY=$(cat ~/.aws/access_key) \
	-e AWS_SECRET_KEY=$(cat ~/.aws/secret_key) \
	-e GPG_PASSPHRASE=supersecretsesame \
	docker
	hack/release.sh

It will build and upload the binaries on the specified bucket (you should use get-nightly.docker.io for general testing, and once everything is fine, switch to get.docker.io).

10. Rejoice!

Congratulations! You're done.
