Random quote application v0.1a-rc

============================================= Introduction

There are two vagrant configurations: a) Single Ngnix over docker with docker-compose and the configuration files are stored in the host disk so you can change the configuration and add them easily to your version control system.

b) Cluster of 1xlb 2xapp on Ngnix with docker-compose and the configuration files are stored in the host disk so you can change the configuration and add them easily to your version control system.

============================================= Known issues:

Vagrant reload - crashes docker Workaround: run vagrant up --provision to re-rerun puppet in all severs. See backlog for more details of future fix

Vagrant 1.8.7 has an issue on my Mac which prevents to download the vagrant machines, Workaround - downgrade to version 1.8.4

============================================= Backlog:

• Improve README doc

• Resolve premissions issue with cluster

• Validate Ngnix configuration

• Add crontab for "puppet apply"

• Add crontab to docker-compose refresh

• Change Cluster Vagrantfile to deploy servers from a single configuration blockquote.

• Improve random quote quote at the html and js level and remove unnecessary code from newquotes.js.

• Improve documentation at the code level with comments.

• Resolve "Warning: Could not retrieve fact fqdn" @puppet provisioning
