A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

Support OnRuby

The operation, development and maintenance of OnRuby can be supported via Patreon at



You can install OnRuby using Docker or a local installation.

Install using Docker

Get containers

Install Docker and Docker Compose if you haven't already. Then:

docker-compose up --build

sudo might be required for docker-compose if you run Docker locally on Linux.

This creates three Docker containers:

  • web for the application
  • box for storing rubygems installations
  • db for the PostgreSQL database

Prepare the database

In another terminal, run the Rake task to set up the database structure.

script/in_docker bundle exec rake db:setup

The script/in_docker allows you to run commands inside the Docker container.

Example: Running a spec inside the Docker container

script/in_docker bundle exec rspec spec/requests/labels_spec.rb

Add usergroup hostnames to /etc/hosts

Add all supported subdomains to your /etc/hosts file:    www.onruby.test hamburg.onruby.test cologne.onruby.test berlin.onruby.test madridrb.onruby.test andalucia.onruby.test

Visit the site

Navigate to the start page for the OnRuby platform at https://www.onruby.test:3000.

This will list links and logos to all the usergroups.

Install locally

On your machine

Install PostgreSQL

# Install PostgreSQL on macOS
brew install postgresql
# or on Ubuntu
sudo apt-get install postgresql postgresql-contrib

# Check if it's running
psql postgres # exit with \q

# Create user and database
createuser -Ps postgres
rake db:setup

Use script/server to run Rails locally, otherwise you need to export the environment options yourself:

bundle --without=production

Add hosts to /etc/hosts

For working with the whitelabel functionality, you need to add all supported subdomains to your /etc/hosts:    www.onruby.test hamburg.onruby.test cologne.onruby.test berlin.onruby.test madridrb.onruby.test andalucia.onruby.test

Access via https://www.onruby.test:3000

Test Data

You don't need any test data to set up a new project!

If you want to have some kind of seed, use this Rake task, to generate some test data:

rake data:create

If you are a Heroku project admin, you can dump Data from Heroku via Taps Gem:

heroku pg:pull HEROKU_POSTGRESQL_MAROON_URL onruby_development


These are the steps to get your Ruby Usergroup Site:

  • Fork this repo
  • Run bundle && bundle exec rake fork:usergroup[MyUsergroup]
  • Create a GitHub Pull Request
  • Lean back and wait :)

If you have a custom domain, you need to configure the DNS.

On the admin site we need to:

  • heroku domains:add []
  • pull the custom domain into cloudflare
  • create a new GitHub app for that domain and add keys via heroku config:add
  • merge the Pull Request
  • deploy to Heroku
  • add admin privileges to someone for the new RUG

Admin Interface

The app comes with a Administrate interface to manage the model data.

In order to access the admin stuff, you need to be a registered user with the "admin role".

Typus is mounted under /admin of your label, so it's for Hamburg.

Stuff to manage (CRUD)

  • Users
  • Events
    • Materials
  • Locations and Companies (Companies are just special Locations)
  • Topics (Subjects for activities that users can request or propose)
  • Jobs (These are displayed at top of the page)
  • Highlights (Special information that you want to display for a short period of time)
