Bucket is a chatterbot built for Slack using Ruby on Rails. It is a port of Dan Broger's fine xkcd-Bucket. As such, it is licensed under the GPLv3.

1. Install ruby 2.1.2
2. Install Postgres 9.3
3. Run bundle install to install the dependencies.
4. Copy config/database.example.yml into config/database.yml and set it up to match your database.
5. Run rake to test that everything works.
6. Run rails s to start the server.

Head to Slack's API page.

You will need an Outgoing Webhook. You will want a URL on which Bucket will listen, something like http://bucket.herokuapp.com/messages.

Set the environment variables required in the production section of config/secrets.yml.

I have a public Pivotal Tracker project where you can see what I want to change with Bucket.
