Python Bindings - v1 and v2

The python-designateclient package comes with python bindings for both versions of the Designate API: v1 and v2. These can be used to interact with the Designate API from any python program.

Introduction - Bindings v2

To view examples of usage please checkout the doc/examples folder, basic usage is:

#!/usr/bin/env python
from designateclient.v2 import client
from designateclient import shell

from keystoneclient.auth.identity import generic
from keystoneclient import session as keystone_session

auth = generic.Password(
 auth_url=shell.env('OS_AUTH_URL'),
 username=shell.env('OS_USERNAME'),
 password=shell.env('OS_PASSWORD'),
 tenant_name=shell.env('OS_TENANT_NAME'))

session = keystone_session.Session(auth=auth)

client = client.Client(session=session)

zone = client.zones.create('i.io.', email='i@i.io')

rs = client.recordsets.create(zone['id'], 'www', 'A', ['10.0.0.1'])

Introduction

Below is a simple example of how to instantiate and perform basic tasks using the bindings.

#!/usr/bin/env python
from __future__ import print_function
from designateclient.v1 import Client

# Create an instance of the client, providing the necessary credentials
client = Client(
    auth_url="https://example.com:5000/v2.0/",
    username="openstack",
    password="yadayada",
    tenant_id="123456789"
)

# Fetch a list of the domains this user/tenant has access to
domains = client.domains.list()

# Iterate the list, printing some useful information
for domain in domains:
    print("Domain ID: %s, Name: %s" % (domain.id, domain.name))

And the output this program might produce:

$ python /tmp/example.py
Domain ID: 467f97b4-f074-4839-ae85-1a61fccfb83d, Name: example-one.com.
Domain ID: 6d3bf479-8a93-47ae-8c65-3dff8dba1b0d, Name: example-two.com.

Authentication

Designate supports either Keystone authentication, or no authentication at all.

Keystone Authentication

Below is a sample of standard authentication with keystone:

#!/usr/bin/env python

from designateclient.v1 import Client

# Create an instance of the client, providing the necessary credentials
client = Client(
    auth_url="https://example.com:5000/v2.0/",
    username="openstack",
    password="yadayada",
    tenant_id="123456789"
)

Below is a sample of standard authentication with keystone, but also explicitly providing the endpoint to use:

Note

This is useful when a development Designate instances authenticates against a production Keystone.

#!/usr/bin/env python

from designateclient.v1 import Client

# Create an instance of the client, providing the necessary credentials
client = Client(
    auth_url="https://example.com:5000/v2.0/",
    username="openstack",
    password="yadayada",
    tenant_id="123456789",
    endpoint="https://127.0.0.1:9001/v1/"
)

No Authentication

Below is a sample of interaction with a non authenticated designate:

#!/usr/bin/env python

from designateclient.v1 import Client

# Create an instance of the client, providing the endpoint directly
client = Client(
    endpoint="https://127.0.0.1:9001/v1/"
)
