Lunchbot for Slack

The Lunchbot can be used to register for Lunches, ask for reservation status and more.

It includes a docker compose file using Flask-Restless + Flask-Sqlalchemy + Postgres. This project includes a HTTP API for CRUD operations. The database is described in flask/app.py

You can browse the api by calling http://127.0.0.1:5000/api/lunch in your browser.

The actual chatbot will be created during the Hackathon "Create your own chatbot! by plista" taking place in June.

Install requirements and Get the code

To install Docker see instructions at https://docs.docker.com/engine/installation/. I used the simple command curl -sSL https://get.docker.com/ | sh

To install Docker Compose see instructions at https://docs.docker.com/compose/install/

Then get the code

git clone --recursive https://github.com/torbenbrodt/lunchbot

Get slack token

Your bot connects via a simple slack-token to the corresponding slack-team. For sake of simplicity the workshop organizers can provide you with token for the hackathon slack-team http://lunchbot-hackathon.slack.com.

Of course you can also use your personal slack channel. In this case get a Bot token from: http://my.slack.com/services/new/bot Afterwards update your docker compose environment

echo "token=xxxx-xxxxxxxxx-xxxx" > .env

Develop, Improve and Run the lunchbot

Start flask and postgres via.

docker-compose up flask some-postgres

Your code lives in chatbot/app/server.js. Here the actual work happens. To run it please execute

docker-compose up chatbot

Debugging in bash

Sometimes docker-composer is just to generic and you want to execute commands on your own.

docker run -it --rm --name my-running-app -v "$PWD/chatbot/app":/usr/src/app/app -w /usr/src/app --env-file .env lunchbot_chatbot /bin/bash
