Testributor - Katana

Katana is part of the Testributor open source Continuous Integration platform. It is the main server application providing the API for the agents, the User Interface and all the logic for Authorization/Authentication.


Katana is a Ruby on Rails application and it needs:

  • PostgreSQL for storage
  • Redis as a PUB/SUB system
  • Socketidio
  • At least one running Sidekiq worker

Running the application

In the future we might provide some easy ways to run Testributor (Docker image, AMI etc) but for now you will have to create and run all components on your own. Here is the walkthrough:

  • Clone this project to a directory on your system. E.g.
git clone git@github.com:testributor/katana.git

Database preparation

  • Move to the cloned project's directory: cd katana
  • Copy config/database.local.sample.yml file to config/database.local.yml:
cp config/database.local.sample.yml config/database.local.yml
  • Edit the file and change the database details to match a PostgreSQL database which you want to use.
  • Unless the database is already created, run rake db:create to create it now.
  • Run rake db:setup to load the schema and prepare the database.

Run Socketidio

Follow the instructions on Socketidio README in order to run socketidio (by default on port 9000).

Start a background Sidekiq worker

For the application to work you need to have at least one running Sidekiq worker. From withing the katana project directory run the following command to start one:

bundle exec sidekiq -c 3 -q mailers -q default -q low

Environment variables

Testributor uses some environment variables for configuration and you will not be able to start the application unless they are defined. These are:

  • GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET You will need to create an application on GitHub as described here to obtain these values.

  • BITBUCKET_CLIENT_ID and BITBUCKET_CLIENT_SECRET These are the same values for Bitbucket. Read how to create an application on Bitbucket here.

  • ENCRYPTED_TOKEN_SECRET Keys and API tokens are stored encrypted in the database. This value is the key used for encryption. Use a big random string value for this variable.

  • SOCKETIO_URL This is the url of the socketidio which you started on a previous step. The default value is "http://localhost:9000" and you don't need to define this variable if this is correct for your system.

Start the application

While in the katana project directory start the Rails server:

bin/rails s


You are more than welcome to contribute to the development of Testributor CI with bug fixes or new features. We suggest that you first open an Issue in order to discuss the bug/feature before jumping to implementation. This will make planning of features more efficient and will save us from duplicate efforts in case someone has already started working on something.

In any case, if you decide to work on something:

  • Fork the project
  • Do your magic
  • Open a Pull Request
  • Wait patiently for someone to review your code

Make sure you test your code. Ask for help if you need it. Here some general guidelines on the subject of contributing.
