rails_app_host: 127.0.0.1
rails_app_platform: "{{ app_user }}"
rails_app_production_ready: true
rails_app_purge_all: false

rails_app_git_repo: https://github.com/mikechau/haproxy-passenger-standalone-rolling-upgrades.git
rails_app_git_branch: master

rails_app_all_instances:
  - id: titanium
    port: 4000
    host: 127.0.0.1
    protocol: tcp

  - id: carbon
    port: 4001

Your playbook:

  vars:
    rails_app_strategy: deploy
    rails_app_platform: production
  roles:
    - role: rails
      rails_app_run: first
      rails_app_type: server
      rails_app_id: titanium
      rails_app_host: 127.0.0.1
      rails_app_port: 4000

    - role: rails
