Ryu experts,
I have a question,
I am writing a ryu app. Is there a way to add command line configuration
arguments when writing an app?
I tried the following also used in wsgi.py app but it didn't work.
from ryu import cfg
CONF = cfg.CONF
CONF.register_cli_opts([
cfg.StrOpt('policy', default='block', help = 'Policy: One of A, B,
C, C'),
cfg.StrOpt('NetworkMask', default='192.168.1.1/24', help = 'Network
Gateway and netmask '),
])
...
I got this error from oslo.
