Trokko

Do you think the steps involved in building a Rails application development environment with Docker are too complicated?

The trokko command solves this for you.

The trokko command prepares the specified Gemfile template. It will prepare a Dockerfile or docker-compose.yml depending on the specified DBMS. Then, it runs rails new and gets you ready to start development right away. It takes about a minute.

The installation process is as follows

$ gem install trokko

Usage:
  trokko generate [NAME]

Options:
  [--ruby-version=RUBY_VERSION]      # Ruby version (docker image tag)
                                     # Default: latest
  [--db=DB]
                                     # Default: mysql
                                     # Possible values: mysql, postgresql
  [--skip-build], [--no-skip-build]  # Skip build
  [--force]                          # Force to execute

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
