Project reference setup with ansible & vagrant

-------------------------------------------------------------------------------
Requirements
	- Vagrant 1.5.x
	- https://github.com/fgrehm/vagrant-cachier
	 	 $ vagrant plugin install vagrant-cachier
	- Ansible in your host machine. For OS X:
	 	 brew install ansible

Introduction

Start by running:
	
	$ ./build.sh new

This will do the following:
	
	- Bring up & provision the virtual machine (if needed)
	- Build the drupal site under drupal/current

After finishing provisioning (first time is always slow) and building the site
you need to install the Drupal site in http://x.x.x.x:8080/install.php
(Note: on rare occasion php-fpm/varnish/e.g. requires to be restarted before
starting to work. You can do this by issuing the following command:

	$ vagrant  ssh -c "sudo service php-fpm restart"
	$ vagrant  ssh -c "sudo service varnish restart"

All Drupal related configurations are under drupal/conf

Drush is usable without ssh access with the drush.sh script e.g:

	$ ./drush.sh cc all

To open up ssh access to the virtual machine:

	$ vagrant ssh

Useful things

At the moment IP is configured in 
	Vagrantfile
		variable INSTANCE_IP

Varnish responds in 
	http://x.x.x.x/

Nginx responds in
	http://x.x.x.x:8080/

Solr responds in
	http://x.x.x.x:8983/solr

MailCatcher responds in
	http://x.x.x.x:1080

-------------------------------------------------------------------------------
Vagrant + Ansible configuration

Vagrant is using Ansible provision stored under the ansible subdirectory.
The inventory file (which stores the hosts and their IP's) is located under 
ansible/inventory. Host specific configurations for Vagrant are stored in 
ansible/vagrant.yml and the playbooks are under ansible/playbook directory.
Variable overrides are defined in ansible/variables.yml.

You should only bother with the following:

	What components do you want to install?
		ansible/vagrant.yml

	And how are those set up?
		ansible/variables.yml

-------------------------------------------------------------------------------
Debugging tools

XDebug tools are installed via the devtools role. Everything should work out 
of the box for PHPStorm. PHP script e.g. drush debugging should also work.

Example sublime text project configuration (via Project->Edit Project):

{
	"folders":
	[
		{
			"follow_symlinks": true,
			"path": "/path/to/ansibleref"
		}
	],

	"settings": 
	{
		"xdebug": {
		    "path_mapping": {
		        "/vagrant" : "/path/to/ansibleref"
		    }
		}
	}
}

Ansible configuration as a git subtree

The directory ansible/playbook contains the ansible configuration as a git 
subtree. These commands are here provided not because you need to run them (you
very rarely have to) but for a reference only.

Adding:

	$ git subtree add --prefix ansible/playbook <url> master --squash

Pulling:

	$ git subtree pull --prefix ansible/playbook <url> master --squash

Pushing:

	$ git subtree push --prefix ansible/playbook <url> master --squash

Committing (as usual):

	$ git commit -m "message"
