Generate GitLab CI pipelines.

Install pipedawg with:

gem install pipedawg

Or add this line to your application's Gemfile:

gem 'pipedawg'

And then execute:

bundle install

Example:

#!/usr/bin/env ruby
# frozen_string_literal: true

require 'pipedawg'

gem_job = Pipedawg::Job.new(
  'build:gem',
  artifacts: ['*.gem'],
  image: 'ruby',
  script: ['bundle install', 'gem build *.gemspec']
)

kaniko_build_job = Pipedawg::Job::Kaniko::Build.new(
  'build:kaniko',
  needs: ['build:gem'],
  retry: 2,
  context:'${CI_PROJECT_DIR}/docker',
  external_files: {'*.gem':'gems'},
  debug: false
)

pipeline = Pipedawg::Pipeline.new 'build:image', jobs: [gem_job, kaniko_build_job]
puts pipeline.to_yaml
pipeline.to_yaml_file('/tmp/pipeline.yaml')

$ cat /tmp/pipeline.yaml

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

Note that by default, Bundler will attempt to install gems to the system, e.g. /usr/bin, /usr/share, which requires elevated access and can interfere with files that are managed by the system's package manager. This behaviour can be overridden by creating the file .bundle/config and adding the following line:

BUNDLE_PATH: "./.bundle"

When you run bin/setup or bundle install, all gems will be installed inside the .bundle directory of this project.

To make this behaviour a default for all gem projects, the above line can be added to the user's bundle config file in their home directory (~/.bundle/config)
