Re: [Ryu-devel] Passing config file to Ryu app

[Yusuke I. <iwa...@gm...>]

Hi,

Ryu uses oslo.config library.
You can use default Ryu configuration file (etc/ryu/ryu.conf) as follow.

# Set params
$ vi etc/ryu/ryu.conf
 ...
 test_param1=12345
 test_param2='test'
 ...

# Get params in your App
$ vi yourapp.py
 ...
   :
 from ryu import cfg
   :
 class SimpleSwitch13(app_manager.RyuApp):
     def __init__(self, *args, **kwargs):
         super(SimpleSwitch13, self).__init__(*args, **kwargs)
           :
         CONF = cfg.CONF
         CONF.register_opts([
             cfg.IntOpt('test-param1', default=0),
             cfg.StrOpt('test-param2', default='default')])
         print 'test_param1 = %d' % CONF.test_param1
         print 'test_param2 = %s' % CONF.test_param2
 ...

# Reinstall ryu
$ sudo python setup.py install

# Run
$ ryu-manager ryu.app.simple_switch_13
loading app ryu.app.simple_switch_13
loading app ryu.controller.ofp_handler
instantiating app ryu.app.simple_switch_13 of SimpleSwitch13
instantiating app ryu.controller.ofp_handler of OFPHandler
test_param1 = 12345
test_param2 = test

Thanks

The documentation says I could use "--config-file" to pass a file to an application, but how do I go about creating the file and extracting the contents from the application?  Can I use json/xml?  Perhaps someone can share an example of a config file?
