Takashi NATSUME d16c3692e6 Log request_id for each api call
Add the function to log 'x-openstack-request-id' or
'x-compute-request-id' in each API call.
If the caller (e.g. heat) uses oslo.log,
the caller's request id in oslo.context and
the callee's request id can be output in the same
log message (same line).

Python bindings to the OpenStack Nova API

Latest Version

Downloads

This is a client for the OpenStack Nova API. There's a Python API (the novaclient module), and a command-line script (nova). Each implements 100% of the OpenStack Nova API.

See the OpenStack CLI guide for information on how to use the nova command-line tool. You may also want to look at the OpenStack API documentation.

python-novaclient is licensed under the Apache License like the rest of OpenStack.

Command-line API

Installing this package gets you a shell command, nova, that you can use to interact with any OpenStack cloud.

You'll need to provide your OpenStack username and password. You can do this with the --os-username, --os-password and --os-tenant-name params, but it's easier to just set them as environment variables:

export OS_USERNAME=openstack
export OS_PASSWORD=yadayada
export OS_TENANT_NAME=myproject

You will also need to define the authentication url with --os-auth-url and the version of the API with --os-compute-api-version. Or set them as an environment variables as well:

export OS_AUTH_URL=http://example.com:8774/v2/
export OS_COMPUTE_API_VERSION=2

If you are using Keystone, you need to set the OS_AUTH_URL to the keystone endpoint:

export OS_AUTH_URL=http://example.com:5000/v2.0/

Since Keystone can return multiple regions in the Service Catalog, you can specify the one you want with --os-region-name (or export OS_REGION_NAME). It defaults to the first in the list returned.

You'll find complete documentation on the shell by running nova help

Python API

There's also a complete Python API, with documentation linked below.

To use with keystone as the authentication system:

>>> from novaclient import client
>>> nt = client.Client(VERSION, USER, PASSWORD, TENANT, AUTH_URL)
>>> nt.flavors.list()
[...]
>>> nt.servers.list()
[...]
>>> nt.keypairs.list()
[...]

Testing

There are multiple test targets that can be run to validate the code.

  • tox -e pep8 - style guidelines enforcement
  • tox -e py27 - traditional unit testing
  • tox -e functional - live functional testing against an existing openstack

Functional testing assumes the existence of a clouds.yaml file as supported by os-client-config (http://docs.openstack.org/developer/os-client-config) It assumes the existence of a cloud named devstack that behaves like a normal devstack installation with a demo and an admin user/tenant - or clouds named functional_admin and functional_nonadmin.
