From Zero to Deployment: Vagrant, Ansible, Capistrano 3 to deploy your Rails Apps to DigitalOcean automatically (part 2)


tl;dr

Use Vagrant to create a VM using DigitalOcean and provision it using Ansible.

Introduction

Parts zero and one of this blog series demonstrates some Ansible playbooks to create a VM ready for Rails deployment using Vagrant. Here we show the Vagrant file that will provision a DigitalOcean droplet for public access.

First thing to do is to install the DigitalOcean plugin:

 
vagrant plugin install vagrant-digitalocean

 

The Vagrantfile for DigitalOcean

# -*- mode: ruby -*-
# vi: set ft=ruby :
# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = 'digital_ocean'
config.vm.box_url = "https://github.com/smdahlen/vagrant-digitalocean/raw/master/box/digital_ocean.box"
config.vm.hostname = "staging"
config.vm.define "staging"
config.vm.provision 'ansible' do |ansible|
ansible.playbook = "devops/user.yml"
ansible.inventory_path = "devops/webhosts"
ansible.verbose = "vvvv"
ansible.sudo = true
end
config.vm.provider :digital_ocean do |provider, override|
override.ssh.private_key_path = '~/.ssh/id_rsa'
override.vm.box_url = "https://github.com/smdahlen/vagrant-digitalocean/raw/master/box/digital_ocean.box"
provider.client_id = ‘<YOUR ID>'
provider.api_key = ‘<YOUR KEY>'
provider.image = "Ubuntu 12.10 x64"
provider.region = "New York 2"
end

end

You can get your ID and Key from the DigitalOcean website once logged on there.

 

Not much to it, eh?

The Ansible files stay mostly the same, apart from the use of ‘root’ wherever ‘vagrant’ was used. And don’t forget to change your inventory file to the IP address given by DigitalOcean. I’ll be thinking about how to automate these parameters too, to have complete hands-free installations.
