[openstack-dev] [Congress] Ramp-up strategy

2014-08-21 Thread Madhu Mohan 
Hi,

Since a few weeks I am trying to get a hold on Congress code base and
understand the flow.

Here is a brief summary what I am trying out:

Prepared a dummy client to send the policy strings to congress_server
listening at the path /policies. This is now changed to v1/policies. I
am using POST request to send the policy string to the server.

The call to server somehow seems to get converted to an action with the
name create_policies
Added a new API create_policies in the api model policy_model.py which
gets the policy string in params.

I am able to call compile.parse() and runtime.initialize() functions from
this API.
The compilation produces a result in the format below:


*Rule(head=[Literal(table=u'error', arguments=[Variable(name=u'vm')],
negated=False)], body=[Literal(table=u'nova:virtual_machine',
arguments=[Variable(name=u'vm')],. *
I am not really sure about how to go about from here to see the policies
actually getting applied and monitored.

Any resource or instructions on getting through the code flow will be of
great help to proceed further.

Thanks in Advance,
Madhu Mohan

Hi Madhu,

We have an end-user tutorial in review right now.  That should help you get 
started understanding the end-to-end flow a bit better.  Look for it to be 
merged today or tomorrow.
