Running a High Availability Service on CoreOS using Docker, Fleet, Flannel, Etcd, Confd & Nginx

View the diagram of what's going on: https://drive.google.com/file/d/0B74l6vUHf9HrMzNrYUlyMm40RWs/view?usp=sharing

Tools used:

coreos: server machine clustering via a shared cloud-config.yml
etcd: key value store for service registration and discovery
fleet: scheduling/failover of docker containers across coreos cluster
flannel: Gives each docker container a unique ip that allows you to access the internal port (i.e. port 80 not 32679)
confd: watch etcd for nodes arriving/leaving - template nginx configuration files / reload nginx on change

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
