1. Introduction

  XOS is comprised of 3 core services:
  
  * A database backend (postgres)
  * A webserver front end (django)
  * A synchronizer daemon that interacts with the openstack backend.

  We have created separate dockerfiles for each of these services, making it easier to
  build the services independently and also deploy and run them in isolated environments. 

2. Database Container
  
  To build and run the database container:
  
  $ cd postgres; make build && make run;

3. XOS container
  
  To build and run the xos webserver container:

  $ cd xos; make build && make run;

  You should now be able to access the login page by visiting http://localhost:80 and
  log in using the default paadmin account. It may be helpful to bootstrap xos with 
  some sample data; deployment, controllers, sites, slices, etc. You can get started by
  loading tosca configuration for the opencloud demo dataset:

  $ cd xos; make runtosca;

  Or you can create you own tosca configuraton file and customize the dataset however you
  want. You can all load your own tosca configuration by setting the TOSCA_CONFIG_PATH 
  environment variable before executing the make command:

  $ cd xos; TOSCA_CONFIG_PATH=/path/to/tosca/config.yaml make runtosca

4. Synchronizer container

  The syncornonizer shares many of the same dependencies as the xos container. The synchronizer 
  container takes advantage of this by building itself on top of the xos image. This means
  you must build the xos image before building the synchronizer image. The XOS and 
  synchronizer containers can run on separate hosts, but you must build the xos image
  on the host that you plan to run the synchronizer container. Assuming you have already 
  built the xos container, executing the following will build and run the synchronizer container:

  $ cd synchronizer; make build && make run
