Engine Yard's Spina Sample Application

Spina is a CMS built upon the Rails framework. It comes in the form of a Rails Engine and must be created inside a host application. This repository contains a Spina host application with some additional tools to help you deploy on Engine Yard. After reviewing this, you should create your own spina application or fork this one and make the appropriate customizations.

Engine Yard won't update Spina versions that often, so you shouldn't expect to pull updates from this repository. We may address eventual security risk issues and enhance the deployment workflow.

Setting up the application

  • Go to your account panel and create an application
  • Use git://github.com/engineyard/spina_sample_app.git for Git Repository URI
  • Give you application a name. We'll use spina for this guide
  • Choose Rails 5 for Web Application Framework

Setting up the environment

  • Choose Puma as your Application Server Stack (*)
  • Use a stable-v5 Stack
  • Use Ruby 2.3 as Runtime
  • Choose Postgresql 9.5.x as your Database Stack (**)

(*) Is you don't find Puma in the application server list, refer to this link.

(**) Spina supports any database ActiveRecord does. We recommend Postgresql specifically for this guide because our sample data loading procedure uses pg_dump and pg_restore commands. Our sample data is the whole Rails 5 api documentation loaded into a CMS system, which is considerably larger than the default one. That way you can make an educated decision after appraising performance.

Booting a cluster

Now you have a chance to define the cluster configuration for this environment. Go ahead and choose a production cluster to take advantage of load balancing and redundancy for the app and database instances. After this, feel free to experiment with different options Engine Yard recommends or spin up your own.

Important steps before deployment

Secrets.yml

Rails 5 makes use of a secrets.yml file to define a variable that verifies the integrity of signed cookies. That file shouldn't be kept in the repository and Engine Yard offers a custom chef recipe to help you with that.

Download or clone this repo, so you can upload your own secrets file to EngineYard.

There's a cookbooks folder in the root of this application. Locate custom-rails_secrets/templates/default and add a file named secrets.yml.{name_of_your_app}.erb(eg: secrets.yml.spina.erb). This file will be ignored by .gitignore, so you don't have to worry committing by mistake. Go ahead and copy example.yml and replace the base_key with the output of rails secret command.

Now let Engine Yard know about that custom Chef Recipe. After installing the engineyard gem go to the root of this repo and run:

ey recipes upload --environment name_of_your_environment

Go to your environment's page and click Apply.

Shared File System

When creating pages on Spina you will have to upload images to the server's file system. As you might have guessed in a multi server configuration all of your instances have to access the images folder. As your provisioning goes on, take this time to create a Shared File System as one of your environment options. The deployment process will take care of linking all of your instances to that mount point.

Using Spina

This installation will create an admin user with the following credentials. You may access the admin panel on http://{host}/admin

Deploying outside of Engine Yard

If you want to deploy this sample app outside of Engine Yard you can follow the steps described in the official guide.

Skip the default step for Loading Seed Data

After the installation, ssh into your box and run the following command to Load our Custom Seed Data:

bundle exec rake db:load_sample_if_empty_db
