Create a Vagrant image file and share on VagrantCloud

by about , ,

Here we will cover how to create a Vagrant Box. In this case I want to install chef-solo over an Ubuntu/trusty image. You can clone all work in this post from this repo https://github.com/jlebrijo/trusty64-chef.

mkdir trusty64-chef
cd trusty64-chef/
rbenv local 2.1.2
gem install bundle

Create Gemfile:

source 'https://rubygems.org'
gem 'vagrant', github: 'mitchellh/vagrant', tag: 'v1.6.4'
gem 'knife-solo'

Install gems:

bundle
bundle install --binstubs .bundle/bin

Create Vagrantfile: ‘vagrant init’. In order to take access to the image, add to Vagrantfile:

config.vm.network :public_network, bridge: "wlan0", ip: "192.168.10.25"

Start box: ‘vagrant up’. Install Chef in the image:

knife solo prepare vagrant@192.168.10.25 ## password: vagrant

Update Ubuntu:

vagrant ssh
sudo apt-get update

Package the Box: `vagrant package –base trusty64-chef_default_1409751631640_92694 –output trusty64-chef.box`

Add to local Box list: `vagrant box add lebrijo/trusty64-chef package.box`

Upload the box to a HTTP server: `scp trusty64-chef.box lebrijoc@files.lebrijo.com:www/lebrijo.com/files`

Create an account and entry in vagrantcloud.com [lebrijo/trusty64-chef](https://vagrantcloud.com/lebrijo/trusty64-chef)

Install RVM in your Ubuntu Desktop

by about ,

You can install RVM with this few commands:

sudo apt-get install curl
curl -L get.rvm.io | bash -s stable --auto
source /etc/profile.d/rvm.sh << or whatever says the console of rvm >>

After that, you need to check which RVM prerequisites depends on :

rvm requirements

Install last ruby version:

rvm install 2.1.2

For .bashrc executing purposes, and execute RVM ruby version when open a project, you can integrate RVM with your Gnome terminal:

RVM gnome-terminal integration
Deeper explanation here: https://rvm.io/integration/gnome-terminal/

My favourite way to configure a Rails project ruby-version and gemset is in Gemfile:

#ruby=ruby-2.1.2
#ruby-gemset=website

But you always you can use .ruby-version and .ruby-gemset files.

In our new collaboration with Tealeaf Academy friends, we are writing about Chef/Vagrant and how to use them to manage and test your servers configuration.

This is a step-by-step guide (including github projects) to bootstrap and cook a basic Rails server:

  • Step 1. Vagrant: Creating your Development environment (Server Virtualization)
  • Step 2. Knife-solo: Kitchen structure
  • Step 3. Librarian: Managing dependencies
  • Step 4. Creating your own cookbook (rails-stack)
  • Step 5. Cook your Vagrant Box
  • Step 6. Cook a real server
  • Step 7. Deploy with Capistrano
  • Conclusions

Enjoy!!
