# ansible-nginx

## Synopsis

This project uses vagrant + ansible (and some homecooked scripting skills) to dynamically create a nginx round-robin load balancer cluster with any number of nodes (default 3) that connects

to the load balancer using etcd as a service discovery

## Requirements

* Vagrant must be installed on the host machine

* Ansible must be installed on the host machine

* Host machine needs to reach https://github.com (for fetching etcd)

* Port 9999 on host machine needs to be unused, otherwise change this port in Vagrantfile

## Instructions

* To change number of nginx nodes used by the load balancer, change the value of the variable 'NUM_NODES' in Vagrantfile

* vagrant up

* run ruby script to calculate the distributed load across the nodes:

```shell

./epicrubylb.rb

Command-line utility for calculating even lb ngix round-robin load.

  ./epicrubylb.rb [-n Number of requests to lb]

  Example: ./epicrubylb.rb -n 100

  Expected output:

  node1: 50

  node2: 50

    -n, --num-requests [Requests]    The total number of request sent to lb

    -h, --help                       help

```
