I need to be able to read in a path file from my simple_switch.py
application.I have added the following code to my simple_switch.py in
python.
LOG = logging.getLogger(__name__)
CONF = cfg.CONF
CONF.register_cli_opts([
cfg.StrOpt('path-file', default='test.txt',
help='path-file')
])
I attempt to start the application as follows.
bin/ryu-manager --observe-links --path-file test.txt
ryu/app/simple_switch.py
However I get the following error.
usage: ryu-manager [-h] [--app-lists APP_LISTS] [--ca-certs CA_CERTS]

ryu-manager: error: unrecognized arguments: --path-file
It does look like I need to register a new command line option somewhere
before I can use it.Can some-one point out to me how to do that? Also can
someone explain how to access the file(text.txt) inside the program?
Regards,
Karthik.
