The Dockerfile in this directory will build a Docker image for running
XOS using the Django development server.  It copies whatever files are 
in the local repository into the image. Here's how to do it:

1. A minimal initial_data.json is provided. The login credentials
   for this initial_data.json are [email protected], 
   password=letmein.

   This initial_data.json doesn't contain any nodes and is suitable
   for fresh installations. To obtain an initial_data.json (for demo
   purposes) that contains an interesting set of Nodes and Slices,
   a dump can be made on portal.opencloud.us:

   1) log in to portal, and run:
         $ sudo /opt/xos/scripts/opencloud dumpdata

   2) replace the initial_data.json file with the dumpdata
      file produced above.

2. $ docker build -t xos .

3. $ docker run -t -i -p 8000:8000 xos

4. Now you will have a bash prompt as root inside the XOS container.
   Start up XOS:
   
   # /opt/xos/scripts/opencloud runserver

You can access the XOS login at http:<server>:8000, where <server> is
the name of the server running Docker.

5. From another terminal window, you can run following command to find
the running container id

   $ docker ps
    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
    a3b668454d21        xos:latest          "/bin/bash"         3 hours ago         Up 3 hours          0.0.0.0:8000->8000/tcp   romantic_bohr

and then you can have another bash prompt (in a different TTY) as root inside the XOS container.

   $ docker exec -it a3b668454d21 bash

and start observer

    # python /opt/xos/xos-observer.py
