[Bug 1626006] Re: wsgi_script based ceilometer-api binary does not support the same CLI arguments as console_script version

[James Page]

Running ceilometer-api from the CLI:

$ ceilometer-api 
Traceback (most recent call last):
  File "/usr/bin/ceilometer-api", line 20, in <module>
    server = wss.make_server('', args.port, load_app())
  File "/usr/lib/python2.7/dist-packages/ceilometer/api/app.py", line 85, in load_app
    cfg_file = CONF.find_file(cfg_path)
  File "/usr/lib/python2.7/dist-packages/oslo_config/cfg.py", line 2580, in find_file
    raise NotInitializedError()
oslo_config.cfg.NotInitializedError: call expression on parser has not been invoked


and from the systemd service:

Sep 21 10:55:02 adapted-tahr ceilometer-api[4932]: usage: ceilometer-api [-h] [--port PORT]
Sep 21 10:55:02 adapted-tahr ceilometer-api[4932]: ceilometer-api: error: unrecognized arguments: --config-file=/etc/ceilometer/ceilometer.conf --log-file=/var/log/ceilometer/ceilometer-api.log

Currently we pass in --config-file and --log-file - the new binary does
not support these options.
