The AsyncOpenStackClient is a asynchronous rest wrapper for the OpenStack API. It provides a nice abstraction for authentication. For method specification, see the official OpenStack documentation: https://docs.openstack.org/queens/api/.
Use pip:
pip install AsyncOpenStackClientfrom asyncopenstackclient import NovaClient, GlanceClient, CinderClient, AuthPassword
# you can either pass credentials explicitly (as shown below)
# or use environmental variables from OpenStack RC file
# https://docs.openstack.org/mitaka/cli-reference/common/cli_set_environment_variables_using_openstack_rc.html
auth = AuthPassword(
auth_url='https://keystone:5999/v3'
username='USER', password='PASS',
project_name='my-project',
user_domain_name='default',
project_domain_name='foo.bar'
)
# alternatively you can also use application_credentials to authenticate with the OpenStack Keystone API
# https://docs.openstack.org/keystone/queens/user/application_credentials.html
alternative_auth = AuthPassword(
auth_url='https://keystone:5999/v3'
application_credential_id="ID",
application_credential_secret="SECRET"
)
nova = NovaClient(session=auth)
glance = GlanceClient(session=auth)
cinder = CinderClient(session=auth)
# api url for each service will be taken from catalog,
# but you may pass `api_url` param to force custom url eg.
# nova = NovaClient(session=auth, api_url='http://my-local-nova:9876/v2/')
