Negroku Stories in Ready Build Status Gem Version


We stopped using capistrano to deploy our applicacions, so this project is not longer maintained.

Negroku is an opinionated collection of recipes for capistrano.

The goal is to be able to deploy ruby applications without the hassle of configure and define all the stuff involved in an application deployment.


Install negroku as a global gem.

$ gem install negroku --pre

Add the negroku gem to your Gemfile development group to lock the version your are going to use.

group :development do
    gem 'negroku', '~> 2.0.0.pre3'

Then run

$ bundle install

Prepare your application

  1. Create your app executing the following command, and just follow the on-screen questions.

    Before you begin, if you're using Negroku 1.X, rename the following files with .old or .bak extension.

    • your_app/Capfile
    • your_app/config/deploy.rb
    • your_app/config/deploy/production.rb (and any other environment)
    $ negroku app create

    App Create

    1. Give your application a name

      This will be used to create the app folder structure in the server.

    2. Please choose your repository url

      You'll need to choose the git respository where your are going deploy your project from. Typically a GitHub repository.

      If you have already initializated your git repository for the project, you'll be offered to choose the remotes of the current repo.

    The app create command will bootpstrap your app (behind the scenes it will run the cap install command and add some customizations)

     Some files and folders will be added to your project.
      |--- Capfile                  # Capistrano load file
      +--- config
            |--- deploy.rb          # Global setting for all environments
  2. Add a new stage for your deployment.

    $negroku stage add

    stage add

    1. Stage Name

      This will be used to create de stage configuration files

    2. Select the branch to use

      Here you'll be presented with your remote branches (git branch -r) so you can choose which one you want to deploy the stage you are creating.

    3. Type the domains to use

      You can pass comma separated domains you want to use in the application

    4. Type the server ur to deploy to

      Set the server where you are going to deploy this stage

    5. Do you want to add rbenv-vars to the server now?

      If you choose 'y'es you wil able to create a .rbenv-vars file in the server with the KEYS and VALUES you choose from your local .rbenv-vars

    The stage add command will create the stage configuration file and run the rbenv:vars:add capistrano task if you chosen to add environmental variables to the applicatin

      +--- config
            +--- deploy
                +--- production.rb    # Specific settings for production server
  3. In the Capfile you can enable and disabled the tasks you need in your application. You only have to comment out the stuff you don't need.

    # Node
    require 'capistrano/nodenv'
    # require 'capistrano/bower'
    # App server
    require 'capistrano3/unicorn'
    # require 'capistrano/puma'
    # Static server
    require 'capistrano/nginx'
  4. Configure your specific settings in the files created above

    1. Common settings for all stages deploy.rb

      Here you can add all the settings that are common to all the stage severs. For example:

      set :unicorn_workers, 1
      set :unicorn_workers_timeout, 30
    2. Per-stage settings staging.rb production.rb

      Here you can add all the settings that are specific to the stage. For example:

      set :branch,        "production"        # Optional, defaults to master
      set :rails_env,        "production"
  5. Commit and push the changes to the repository

To deploy your application you just need to run capistrano task to do so.

$ cap staging deploy  # to deploy to the staging stage
