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

export VERSION=vXXX
git checkout release
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

docker run -privileged -lxc-conf=lxc.aa_profile=unconfined docker hack/make.sh test

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 VERSION 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. Apply tag

git tag -a v$VERSION # Don't forget the v!
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. Go to github to merge the bump_$VERSION into release

10. Publish binaries

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

git checkout release
git fetch
git reset --hard origin/release
docker build -t docker .
docker run  \
       -e AWS_S3_BUCKET=test.docker.io \
       -e AWS_ACCESS_KEY=$(cat ~/.aws/access_key) \
       -e AWS_SECRET_KEY=$(cat ~/.aws/secret_key) \
       -e GPG_PASSPHRASE=supersecretsesame \
       -privileged -lxc-conf=lxc.aa_profile=unconfined \
       -t -i \
       docker \
       hack/release.sh

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

11. Rejoice!

Congratulations! You're done.
