Example of Zookeeper and Solr cluster with Docker networking
------------------------------------------------------------

In this example I'll create a cluster with 3 ZooKeeper nodes and 3 Solr nodes, distributed over 3 machines (trinity10, trinity20, trinity30).
I'll use an overlay network, specify fixed IP addresses when creating containers, and I'll pass in explicit `/etc/hosts` entries to make sure they are available even when nodes are down.
I won't show the configuration of the key-value store to configuration to enable networking, see [the docs](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) for that.
I'll not use Docker Swarm in this example, but specifically place and configure containers where I want them by ssh'ing into the appropriate Docker host.

To make this example easier to understand I'll just use shell commands.
For actual use you may want to use a fancier deployment tool like [Fabric](http://www.fabfile.org).
