Mattermost Coffeebot

Mattermost Coffeebot is a bot written in Python that interacts with the Mattermost API using mattermostdriver and pairs users in your Mattermost team on a regular basis to meet each other.

The bot will take users within a specific channel and message random pairs to meet up. The channel and frequency of these pairings can be configured.

Features

  • Written in Python
  • Uses the Mattermost API
  • Automatically pairs Mattermost users
  • Uses past pairing data to pair people with people they have not been paired with before
  • Configurable pairing times (by modifying cronjob)

Future Features

  • Follow-ups to make sure paired users actually met
  • Better deployment process (deployment script)

Technologies Used

  • Python 3.4+
  • SQLite
  • Docker

Deployment

As of right now, the project is deployed by manually cloning the repository onto a server (such as an AWS EC2 instance), installing the dependencies, creating the environment variables, and setting up a cronjob.

The database is only used for storing previous pairings in order to increase the probability of pairing each user with another user they haven't been paired with before. Should the database be lost, any previous data will be gone, but the bot will still function, just without any data on previous pairings.

Due to this, if you do use SQLite for your database, it is not ideal to use the Docker container on production because your database will be gone if your container gets stopped. However, theoretically, if you use a database hosted on a separate server or on RDS, it should be safe to use the Docker container.

Here are the current steps to deploying:

  1. Clone the repository into a directory

  2. Install Python 3.4+, pip, and cron.

    • On Ubuntu, this can be done by running sudo apt-get update && apt-get install -y -qq cron python3 python3-pip
  3. Install the Python packages by running sudo pip3 install -r requirements.txt in the directory

  4. Create a .env file in the directory with all of your credentials/settings following the same format as the example.env file supplied

  5. Set up a cronjob with your frequency following the same format as the example.crontab file supplied

    • This can be done by running crontab -e and adding the cronjob there

Development

In order to set up a local development environment:

This assumes that you already have Docker installed

  1. Clone the repository into a directory

  2. Create a .env file in the directory with all of your credentials/settings following the same format as the example.env file supplied

  3. Create a crontab file in the directory with your frequency following the same format as the example.crontab file supplied

  4. Build the Docker image by running docker-compose build

  5. Create the Docker container by running docker-compose up

  6. Run bash in the container by running docker exec -ti <CONTAINERID> bash

  7. Run the command pair (or allow the cronjob that was set up to run it)

If you make any changes to the bot, you will have to rebuild the Docker image to apply the changes.
