Ruby on Rails App Deployment Demo

This project builds a Ruby on Rails-based app inside a VM, using Passenger and Nginx to run the app. It is meant as a demonstration of web application deployments (in this case, a Rails-based app) using Ansible.

Building the VM

  1. Download and install VirtualBox.
  2. Download and install Vagrant.
  3. [Mac/Linux only] Install Ansible.
  4. Run ansible-galaxy install -r requirements.yml in this directory to get the required Ansible roles.
  5. Run vagrant up to build the VM and deploy the version of the app specified in playbooks/vars.yml.

Once the VM is built, you can visit http://192.168.33.7/ (or whatever domain name you point to that IP address in your local hosts file) to view the demo app.

Deploying application updates

The first 'production' release of this demo app is version 2.0.1, which includes a basic interface for viewing and managing Articles. Subsequent releases can be deployed by incrementing the app_version in playbooks/vars.yml, then running the Ansible provisioner again with vagrant provision.

Some notable releases you could test:

  • 2.0.1: First stable release with Article CRUD deployable on modern Ruby versions.
  • 2.1.0: Includes a fancy new header with a linear gradient background. Marketing is happy.
