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.

Command-line API

Installing this package gets you a shell command, trove, 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-database-api-version (default is version 1.0). Or set them as an environment variables as well:

export OS_AUTH_URL=http://example.com:5000/v2.0/
export OS_AUTH_URL=1.0

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.

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

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

Python API

There's also a complete Python API.

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, TENANT_NAME, AUTH_URL)
>>> nt.datastores.list()
[...]
>>> nt.flavors.list()
[...]
>>> nt.instances.list()
[...]
