Using openstack.config in an Application¶
Usage¶
The simplest and least useful thing you can do is:
python -m openstack.config.loader
Which will print out whatever if finds for your config. If you want to use it from python, which is much more likely what you want to do, things like:
Get a named cloud.
import openstack.config
cloud_region = openstack.config.OpenStackConfig().get_one(
'internap', region_name='ams01')
print(cloud_region.name, cloud_region.region, cloud_region.config)
Or, get all of the clouds.
import openstack.config
cloud_regions = openstack.config.OpenStackConfig().get_all()
for cloud_region in cloud_regions:
print(cloud_region.name, cloud_region.region, cloud_region.config)
argparse¶
If you’re using openstack.config from a program that wants to process command line options, there is a registration function to register the arguments that both openstack.config and keystoneauth know how to deal with - as well as a consumption argument.
import argparse
import sys
import openstack.config
config = openstack.config.OpenStackConfig()
parser = argparse.ArgumentParser()
config.register_argparse_arguments(parser, sys.argv)
options = parser.parse_args()
cloud_region = config.get_one(argparse=options)
