Implementation of simple Service Discovery with Consul, Registrator and Nginx in a Dockerized environment.

Run setup.sh to get everything up and running, then run curl localhost multiple times to see how requests are served form different applications.

How it is done:

1. Dockerize simple NodeJs app
2. Use Consul as service discovery tool for storing container data in a KV storage
3. Use registrator as service discovery tool for inspecting containers
4. Use nginx as reverse proxy
5. Use Consul-template for configuring nginx automatically

How to stop: docker stop consul registrator nginx node3 node2 node1 consul-tpl
