Release bot Build Status PyPI version

This is a bot that helps maintainers deliver their software to users. It is meant to watch github repositories for release pull requests. The PR must be named in this format 0.1.0 release. No other format is supported yet. Once the PR is merged, bot will create a new Github release, PyPi and Fedora respectively. Changelog will be pulled from root of the repository and must be named Changelog for the new version must begin with version heading, i.e # 0.1.0. Everything between this heading and the heading for previous version will be pulled into the changelog.

Alternatively, you can let the bot do the boring work, update __version__ variable and fill changelog with commit messages from git log. You can trigger this action by creating an issue and name it the same as you would a release PR, e.g. 0.1.0 release. All you have to do after that is merge the PR that the bot will make.

The bot works with pypa/setuptools_scm plugin. If you're using it, you don't need to care about __version__ at all. You can be also sure that the bot will make the PyPI release correctly — before it releases the software, it checks out the tag in the git repo.

A release-conf.yaml file is required. See Configuration section for details.

Once a Github release is complete, bot will upload this release to PyPI. Note that you have to setup your login details (see Requirements).

After PyPI release, if enabled in release-conf.yaml, bot will try to release on Fedora dist-git, on master branch and branches specified in configuration. It should not create merge conflicts, but in case it does, you have to solve them first before attempting the release again.


There are two yaml configuration files:

  1. conf.yaml -- a config for the bot itself with some sensitive data
  2. release-conf.yaml -- stored in upstream repository and contains info on how to release the specific project.

Private repository

You need to setup a git repository, where you'll store the conf.yaml and .pypirc files. If you are releasing on Fedora, you will also need to add id_rsa (a private ssh key that you configured in FAS) and fedora.keytab (kerberos keytab for fedora). If this is not a local repository, make sure it's private so you prevent any private info leaking out. If the path to conf.yaml is not passed to bot with -c/--configuration, bot will try to find it in current working directory.

Here are the conf.yaml configuration options:

Option Description Required
repository_name Name of your Github repository Yes
repository_owner Owner of the repository Yes
github_token Github personal access token Yes
github_username Name of the account that the github_token belongs to. Only needed for triggering the bot on an issue. No
github_app_installation_id Installation ID (a number) of the Github app. No
github_app_id ID (a number) of the Github app. No
github_app_cert_path Path to a certificate which Github provides as an auth mechanism for Github apps. No
fas_username FAS username. Only need for releasing on Fedora No
refresh_interval Time in seconds between checks on repository. Default is 180 No

Sample config named conf.yaml can be found in this repository.

Regarding github_token, it's usually a good idea to create a Github account for the bot (and use its Github API token) so you can keep track of what changes were made by bot and what are your own.

You can also create a Github app and use it as an authentication mechanism for the bot. For that you need to specify the three config values prefixed with github_app.

Upstream repository

You also have to have a release-conf.yaml file in the root of your upstream project repository. Here are possible options:

Option Meaning Required
python_versions List of major python versions that bot will build separate wheels for Yes
changelog List of changelog entries. If empty, changelog defaults to $version release No
author_name Author name for changelog. If not set, author of the merge commit is used No
author_email Author email for changelog. If not set, author of the merge commit is used No
fedora Whether to release on fedora. False by default No
fedora_branches List of branches that you want to release on. Master is always implied No
trigger_on_issue Whether to allow bot to make PRs based on issues. False by default. No
labels List of labels that bot will put on issues and PRs No

Sample config named release-conf-example.yaml can be found in this repository.


Releasing to PyPI requires to have wheel package both for python 2 and python 3, therefore please install requirements.txt with both versions of pip. You also have to setup your PyPI login details in $HOME/.pypirc as described in PyPI documentation. If you are releasing to Fedora, you will need to have an active kerberos ticket while the bot runs or specify path to kerberos keytab file with -k/--keytab. Also, fedpkg requires that you have ssh key in your keyring, that you uploaded to FAS.

Docker image

To make it easier to run this, release-bot is available as an source-to-image builder image.

You can then create the final image like this:

$ s2i build $CONFIGURATION_REPOSITORY_URL usercont/release-bot app-name

where $CONFIGURATION_REPOSITORY_URL is link to repository with conf.yaml and .pypirc files.

To test it locally, you can the run the final image like this:

$ docker run <app-name>

once all changes, configuration files exist in GitHub and git repository contains needed files, you can try to create an issue in your GitHub repository with string like "X.Y.Z release" and you can see log like this:

$ docker run meta-test-family-bot
---> Setting up ssh key...

11:47:57.608          DEBUG  ['git', 'clone', '', '.']

OpenShift template

You can also run this bot in OpenShift using openshift-template.yml in this repository. You must set two environment variables, the $APP_NAME is the name of your release-bot deployment, and $CONFIGURATION_REPOSITORY which contains configuration for the release-bot. The contents of the repository are described above. Note that if you use private repository (which you absolutely should), you will need to set up a new OpenShift secret named release-bot-secret to authenticate. It can be a ssh private key that you can use to access the repository (for GitHub see deploy keys). Here's an guide on how to do that in OpenShift GUI, or another guide that uses oc commandline tool.

By default, the release-bot builder image won't update itself when a new version of this image is pushed to docker hub. You can change it by uncommenting lines with #importPolicy: and #scheduled: true in openshift-template.yml. Then the image will be pulled on a new release.
