This project is an Ansible playbook for provisioning and deploying a Rails/MySQL app to an Ubuntu server. It is intended to be added to an existing Rails application folder. Tested with: Rails 5.1.5, Ruby 2.4.3, Ubuntu 16.04 (Xenial).

Setup

  1. Ansible >= 2.4.1 must be installed

  2. This playbook assumes you are targeting MySQL for your production database and have gem 'mysql2' included in your Gemfile.

  3. From your Rails application folder run:

    \curl -sSL https://raw.githubusercontent.com/bradymholt/ansible-rails/master/installer.sh | bash

    which will:

    1. Add this project to a new folder in your app called "ops"
    2. Initialize the config file
    3. Add 2 new rake tasks to your Rakefile: provision and deploy.

    If you would prefer, you can run the commands in this file manually.

  4. Edit the ops/config.yml file and add your project configuration

Provisioning

Provisioning is used to to setup the the server and initially deploy the application.

To provision your server, run: rake provision. This will do the following:

  • Install the following:
    • RVM
    • Nginx
    • Phusion passenger
    • MySQL
    • Libraries: libxslt-dev, libxml2-dev, libmysqlclient-dev, imagemagick
  • Create a user with ssh access and sudo authorization
  • Setup a daily backup job to backup MySQL database to S3
  • Create an app directory with appropriate permissions where Nginx config is pointing to
  • Configure TLS (https) via Let's Encrypt
  • Define an environment variable named SECRET_KEY_BASE with a unique uuid value.
  • Deploy the application:
    • Precompile assets locally with rake assets:precompile.
    • Copy app files to to remote server in the deploy directory
    • Update config/database.yml on remote server with correct production db config
    • Run the following remotely:
    • bundle install
    • rake db:migrate RAILS_ENV="production"
    • rake tmp:clear
    • rake log:clear
    • touch tmp/restart.txt (restart the app)

Deploying

If you have already provisioned your server and want to redeploy changes to your Rails app, run rake deploy. This will only run the deploy tasks from the playbook and be much faster.
