Release Process

Dokku is released in intervals at most three weeks apart, though may be released much quicker.

To propose a release, the following tasks need to be performed:

  • The installable version must be changed in the docs/ file.
  • The installable version must be changed in the file.
  • The installable version must be changed in the contrib/dokku-installer.rb file.
  • A list of changes must be made in the
  • A tag must be created locally with your release version
  • Debian packages must be created via vagrant up build
  • The packages should be uploaded to
  • All changes are pushed to master and the tag should be turned into a release which will contain the changelog.


Dokku follows semver standards. As we are not yet at a stable release, breaking changes will require only a minor release, while all other changes only require a patch release. Once we hit stable, breaking changes will require a major release.

Tags should be created via the following method:

git tag v0.9.9

At the moment, tags need not be signed, though that may change in the future.

Debian Packages

The build target in the dokku Vagrantfile creates debian packages for dokku at a point in time. The version will be based upon the latest local tag - you may create your own, internal tags/releases if that is so desired.

Debian package information is held in the debian directory of the dokku project.

For the public project, releases should be pushed to after a tag is created but before said tag is pushed to github. The following may be the release workflow:

git tag v0.9.9
vagrant up build
package_cloud push dokku/dokku/ubuntu/trusty dokku_0.9.9_amd64.deb

If new versions of other packages were created, these should also be pushed at this time.
