Github integration for Mattermost

Inspired by mattermost-integration-gitlab this program creates a server using flask that listens for incoming GitHub event webhooks. These are then processed, formatted, and eventually forwarded to Mattermost where they are displayed inside a specified channel.

Requirements

System requirements

• Python3 or Python2

Application requirements

• Flask (install with pip install flask)
• requests (install with pip install requests)
• (optional) PIL (install with pip install pillow) - needed to hide big Github avatars

All requirements can also be installed using the command

pip install -r requirements.txt

Installation and usage

Method 1: running the application from the project directory

1. Clone the repository
2. Within the mattermostgithub directory, copy config.template to config.py and edit it with your details. For example:

NAME = "Github"
_URL = "yourdomain.org/github.png"
ERMOST_WEBHOOK_URLS = {
'default' : ("yourdomain.org/hooks/hookid", "off-topic"),
'teamname/repositoryname' : ("yourdomain.org/hooks/hookid2", "repository-channel-id"),
'teamname' : ("yourdomain.org/hooks/hookid3", "town-square"),
'teamname/unimportantrepo' : None,

UB_IGNORE_ACTIONS = {
"issues": ["labeled", "assigned"],

ET = 'secretkey'
_AVATARS = True
ER = {
'hook': "/"
'address': "0.0.0.0"
'port': 5000

Start the server with python server.py.

Method 2: installing the application with pip

1. Create a virtualenv:

ualenv -p python3 env
v/bin/activate

1. Install with pip

install git+https://github.com/softdevteam/mattermost-github-integration

1. Download config.template and save it as config.py on your machine, changing your details as described above.

The project can then be run as a flask application:

rt FLASK_APP=mattermostgithub
rt MGI_CONFIG_FILE=path/to/config.py
k run

Webhooks

GitHub messages can be delegated to different Mattermost hooks. The order is as follows:

• First try to find a hook for the repositories full name.
• If that fails, try to find a hook for the organisation name.
• Otherwise use the default hook.

Repositories can be blacklisted by setting them to None instead of (url, channel).

Ignore actions

Specific Github events can be ignored by adding GITHUB_IGNORE_ACTIONS to config.py. In the example above labeled and assigned events for issues are ignored, while opened, closed, etc. events will continue to show up on Mattermost.

Server settings

The server is listening by default on address 0.0.0.0, port 5000, and using / as base route. Make sure to point your Github webhooks to http://yourdomain.org:5000/.

If you have a proxy/load-balancer in front of your machine, and do not want to expose port 5000 to the outside, change the SERVER['hook'] value and redirect it to this service. For example, if SERVER['hook'] is /hooks/github, your Github webhooks would be http://yourdomain.org/hooks/github.

Secret

If you don't want to use a secret set the field to None.

Deploying with Docker

To deploy with Docker, make sure you have Docker installed and run:

er build --rm=true -t mm-github .
er run --rm -v "$(pwd)":/home/app -w /home/app -p 5000:5000 -ti mm-github

If you want to run in background mode, change the option --rm for -d.

Supported Events

Not all Github events are forwarded to Mattermost. Currently supported events are:

• Ping events (send when first adding the Github webhook)
• Commit pushes and comments
• Issues (open, close, comment)
• Pull Requests (create, merge, remove, comment)
• Create/Delete repositories
• Create/Delete branches and tags

All other events will report back to GitHub with 400 Not Implemented.

Known issues

• Channel names need to use the spelling that is used in their URL (the channel ID), e.g. instead of Town Square it needs to be town-square.

• If you set a custom username (as shown in the default config), make sure you also set Enable webhooks and slash commands to override usernames under Custom Integrations in the System Console to True. Otherwise the bots username will be that of the person that setup the Mattermost integration.
