AsyncOpenStackClient 0.8.1

Basic OpenStack async client library using asyncio

AsyncOpenStackClient

Introduction

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/.

Installation

Use pip:

pip install AsyncOpenStackClient

Usage

from asyncopenstackclient import NovaClient, GlanceClient, CinderClient, AuthPassword

# you can either pass credentials explicitly (as shown below)
# or use enviormental 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'
)
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/')

await nova.init_api()
await glance.init_api()
await cinder.init_api()


servers = await nova.servers.list(name='testvm')
vm = await nova.servers.get(server_id)

action_spec = {'os-stop': None}
await nova.servers.run_action(server_id, **action_spec)


specs = {
    "name": 'some_name',
    "flavorRef": 'flavor_id',
    "imageRef": 'image_id',
    "security_groups": [{'name': 'group1'}, {'name': 'group2'}]
    "user_data": base64.b64encode(userdata).decode('utf-8')
}
response = await nova.servers.create(server=specs)
print(response)

volume = {"size": 200,
          "imageRef": "image_id",
          "name": "some_name"}

response = await cinder.volumes.create(volume=volume)
print(response)
