# Test and Deploy a ruby application with GitLab CI/CD
|
|
|
|
This example will guide you how to run tests in your Ruby on Rails application and deploy it automatically as Heroku application.
|
|
|
|
You can checkout the example [source](https://gitlab.com/ayufan/ruby-getting-started) and check [CI status](https://gitlab.com/ayufan/ruby-getting-started/builds?scope=all).
|
|
|
|
## Configure the project
|
|
|
|
This is what the `.gitlab-ci.yml` file looks like for this project:
|
|
|
|
```yaml
|
|
test:
|
|
stage: test
|
|
script:
|
|
- apt-get update -qy
|
|
- apt-get install -y nodejs
|
|
- bundle install --path /cache
|
|
- bundle exec rake db:create RAILS_ENV=test
|
|
- bundle exec rake test
|
|
|
|
staging:
|
|
stage: deploy
|
|
script:
|
|
- gem install dpl
|
|
- dpl --provider=heroku --app=gitlab-ci-ruby-test-staging --api-key=$HEROKU_STAGING_API_KEY
|
|
only:
|
|
- master
|
|
|
|
production:
|
|
stage: deploy
|
|
script:
|
|
- gem install dpl
|
|
- dpl --provider=heroku --app=gitlab-ci-ruby-test-prod --api-key=$HEROKU_PRODUCTION_API_KEY
|
|
only:
|
|
- tags
|
|
```
|
|
|
|
This project has three jobs:
|
|
1. `test` - used to test Rails application,
|
|
2. `staging` - used to automatically deploy staging environment every push to `master` branch
|
|
3. `production` - used to automatically deploy production environment for every created tag
|
|
|
|
## Store API keys
|
|
|
|
You'll need to create two variables in your project's **Settings > CI/CD > Variables**:
|
|
|
|
1. `HEROKU_STAGING_API_KEY` - Heroku API key used to deploy staging app,
|
|
2. `HEROKU_PRODUCTION_API_KEY` - Heroku API key used to deploy production app.
|
|
|
|
Find your Heroku API key in [Manage Account](https://dashboard.heroku.com/account).
|
|
|
|
## Create Heroku application
|
|
|
|
For each of your environments, you'll need to create a new Heroku application.
|
|
You can do this through the [Dashboard](https://dashboard.heroku.com/).
|
|
|
|
## Create Runner
|
|
|
|
First install [Docker Engine](https://docs.docker.com/installation/).
|
|
To build this project you also need to have [GitLab Runner](https://about.gitlab.com/gitlab-ci/#gitlab-runner).
|
|
You can use public runners available on `gitlab.com`, but you can register your own:
|
|
|
|
```
|
|
gitlab-runner register \
|
|
--non-interactive \
|
|
--url "https://gitlab.com/" \
|
|
--registration-token "PROJECT_REGISTRATION_TOKEN" \
|
|
--description "ruby-2.2" \
|
|
--executor "docker" \
|
|
--docker-image ruby:2.2 \
|
|
--docker-postgres latest
|
|
```
|
|
|
|
With the command above, you create a Runner that uses [ruby:2.2](https://hub.docker.com/r/_/ruby/) image and uses [postgres](https://hub.docker.com/r/_/postgres/) database.
|
|
|
|
To access PostgreSQL database you need to connect to `host: postgres` as user `postgres` without password.
