Python bindings to the OpenStack Trove API

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

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

The project is hosted on Launchpad, where bugs can be filed. The code is hosted on Github. Patches must be submitted using Gerrit, not Github pull requests.

This code a fork of Jacobian's python-cloudservers If you need API support for the Rackspace API solely or the BSD license, you should use that repository. python-troveclient is licensed under the Apache License like the rest of OpenStack.

Command-line API

Installing this package gets you a shell command, trove, that you can use to interact with any Rackspace compatible API (including OpenStack).

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 --version. Or set them as an environment variables as well:

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.

Argument --profile is available only when the osprofiler lib is installed.

You'll find complete documentation on the shell by running trove help:: usage: trove [--version] [--debug] [--os-username <auth-user-name>] [--os-password <auth-password>] [--os-tenant-name <auth-tenant-name>] [--os-tenant-id <auth-tenant-id>] [--os-auth-url <auth-url>] [--os-region-name <region-name>] [--service-type <service-type>] [--service-name <service-name>] [--bypass-url <bypass-url>] [--database-service-name <database-service-name>] [--endpoint-type <endpoint-type>] [--os-database-api-version <database-api-ver>] [--os-cacert <ca-certificate>] [--retries <retries>] [--json] <subcommand> ...

Optional arguments:

Without key the profiling will not be triggered even if osprofiler is enabled on server side. Defaults to env[OS_PROFILE_HMACKEY].

Python API

There's also a complete Python API, but it has not yet been documented.

Quick-start using keystone:

# use v2.0 auth with http://example.com:5000/v2.0/")
>>> from troveclient.v1 import client
>>> nt = client.Client(USERNAME,
                       PASSWORD,
                       project_id=TENANT_NAME,
                       auth_url=AUTH_URL))
>>> nt.instances.list()
