A little more documentation

[drjrkuhn]

I'm trying to use this repo as a basis for a new omero distribution over several VMs. I've been trying to span the knowledge gap between this simple example and the very complex IDR ansible deployment. I'm finding it a little difficult to move from single VM deployment to multiple VM deployment. A little more documentation or a README here would be extremely helpful!

For example:

• How does everything connect?
• in the role: ome.postgresql
  • How does the postgresql_server_auth work?
  • Should the address line be { hostvars['omero-server'].ansible_eth0.ipv4.address }} instead of 0.0.0.0/0
  • Or is address is it zero to prevent any outside connections.
• Which server should I expose to the public as the proxy to redirect requests?

I figured some of this out. See pull request #9 (comment)
