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
