#Ansible playbooks This is a set of ansible playbooks and roles which can be developed and tested via vagrant and are meant to be used for provisioning nodes accross an inventory.

##Requirements

• python >= 2.7 < 3
• ruby
• ansible
• vagrant
• rake

Set up

# Get necessary packages
apt-get install vagrant #it's best to get the deb package directly from vagrantup.com
gem install rake
pip install ansible

Stage environment configuration

Through many variables, things can be done differently using vagrant and ansible via rake. These variables can be held inside a configuration file named config.rb. You can start by copying this repo's config.rb.sample and read its instructions to get an idea of what you can do to tweak your stage environment.

Current git branch as the stage environment

A git-based approach has been implemented for a multi-stage ansible codebase. Instead of using a complex directory layout to separate things among hosts groups in ansible, the name of the current git branch is used by rake to determine what hosts are going to be targeted by ansible-playbook. Therefore, the name of the current git branch is treated as an expected target host group inside your $ansible_inventory.

In this way, there can be a guaranteed separated playbook development to make sure different environments can be developed using different role versions without compromising its siblings, most importantly, deployments can be made on the right hosts comfortably (no room for accidents).

rake Tasks

All necessary operations for development/deployments are done through rake tasks

Install third-party dependencies

First of all, once you have cloned this repo, you need to set up its dependencies

# This will install ansible inside a virtualenv + necessary roles
rake install

• If you wish to only install the ansible bundle run rake install_ansible
• If you only want to install/reinstall ansible roles you can execute rake install_roles

List boxes that are going to be provisioned by ansible

# This will list vagrant boxes only
rake vagrant:list

# This will use your $ansible_inventory in config.rb
# You can use this approach to list hosts outside your vagrant environment
rake list

Test your $ansible_playbook with your Vagrant boxes

# this will bring your vagrant box(es) up and provision them 
# with your $ansible_playbook
rake vagrant:test

Deploy your changes on your stage environment

# This will provision your hosts set in your $ansible_inventory using your $ansible_playbook
rake deploy
