Ruby with Bitbucket Pipelines

Here's how you can configure the bitbucket-pipelines.yml file to build and test a Ruby project.

Specify your Ruby version with Docker

Bitbucket Pipelines runs all your builds in Docker containers using an image that you specify at the beginning of your configuration file. You can easily use Ruby with Bitbucket Pipelines by using one of the official Ruby Docker images on Docker Hub. If you use the default Ruby image it will come with the bundler installed by default to help you manage your dependencies.

For instance, you can use Ruby 2.4.0 by specifying it at the beginning of your bitbucket-pipelines.yml file:

image: ruby:2.4.0
pipelines:
  default:
    - step:
        script:
          - ruby -v

If you want to use a different version of Ruby you simply need to change the tag for the Ruby Docker image. For example, here's how you would start a container with Ruby 2.3.3:

image: ruby:2.3.3

You can find a list of all supported Ruby versions and corresponding image tags at https://hub.docker.com/r/library/ruby/.

Note that the Rails Docker images have been deprecated in favor of the standard Ruby images mentioned above.

Install dependencies

If you are using a Gemfile, you can simply run bundle install at the beginning of your script to install all the dependencies:

image: ruby:2.4.0
pipelines:
  default:
    - step:
        script:
          - bundle install

You can also install dependencies explicitly with the gem install command:

image: ruby:2.4.0
pipelines:
  default:
    - step:
        script:
          - gem install rails

データベース

Bitbucket Pipelines allows you to launch extra services during the execution of your pipeline by defining the service, and instantiating it on the appropriate step.

We've created a list of examples of how to configure your bitbucket-pipeline.yml file for your favourite database.

テスト

You simply need to add to your bitbucket-pipelines.yml file the same commands that you would run locally to test your application. For instance, if you are using RSpec the following configuration would install your dependencies and then run your tests:

image: ruby:2.4.0
pipelines:
  default:
    - step:
        script:
          - bundle install
          - rspec

 

If you are building a Rails application it is highly likely that you will require a database to run your tests. We've created a list of examples of how to configure your bitbucket-pipeline.yml.

For example, here's how you'd configure a PostgreSQL database as part of your pipeline:

bitbucket-pipelines.yml
image: ruby:2.3.1

pipelines:
  default:
    - step:
        script: # Modify the commands below to build your repository.
          - export DATABASE_URL=postgresql://test_user:test_user_password@localhost/pipelines
          - bundle install
          - rake db:setup
          - rake db:test:prepare
          - rspec
        services:
          - postgres
 
definitions:
  services:
    postgres:
      image: postgres
      environment:
        POSTGRES_DB: pipelines
        POSTGRES_USER: test_user
        POSTGRES_PASSWORD: test_user_password
