Google DNS Driver Documentation

Google Cloud DNS is a scalable, reliable and managed authoritative Domain Name System (DNS) service running on the same infrastructure as Google.

Instantiating the driver

The Google Cloud DNS driver supports three methods of authentication: * Service accounts * Installed Application * Internal authentication

To instantiate the driver, pass authentication tokens to the constructor as shown below:

1. Getting Driver with Service Account authentication

With local key file:

from libcloud.dns.types import Provider
from libcloud.dns.providers import get_driver

DNSDriver = get_driver(Provider.GOOGLE)
driver = DNSDriver("service account email", "keyfile location", project="project ID")

With Service Account credentials as dict:

from libcloud.dns.types import Provider
from libcloud.dns.providers import get_driver

credentials = {
    "type": "service_account",
    "project_id": "my_project",
    "private_key": "-----BEGIN PRIVATE KEY-----\nmy_private_key_data\n"
    "-----END PRIVATE KEY-----\n",
    "client_email": "my_email",
}

DNSDriver = get_driver(Provider.GOOGLE)
driver = DNSDriver("your_service_account_email", credentials, "your_project_id")

2. Getting Driver with Installed Application authentication

from libcloud.dns.types import Provider
from libcloud.dns.providers import get_driver

DNSDriver = get_driver(Provider.GOOGLE)
driver = DNSDriver("client ID", "client secret", project="project ID")

3. Using GCE Internal Authorization

from libcloud.dns.types import Provider
from libcloud.dns.providers import get_driver

# This example assumes you are running an instance within Google Compute Engine
# in which case you only need to provide the project ID.
DNSDriver = get_driver(Provider.GOOGLE)
driver = DNSDriver("", "", project="project ID")

create_record(name, zone, type, data, extra=None)

Create a new record.

Parameters:

• name (str) – Record name fully qualified, with a ‘.’ at the end.
• zone (Zone) – Zone where the requested record is created.
• type (RecordType) – DNS record type (A, AAAA, …).
• data (str) – Data for the record (depends on the record type).
• extra (dict) – Extra attributes. (optional)

Return type:

Record

create_zone(domain, type='master', ttl=None, extra=None)

Create a new zone.

Parameters:

• domain (str) – Zone domain name (e.g. example.com.) with a ‘.’ at the end.
• type (str) – Zone type (master is the only one supported).

Parameters:

• zone (Zone) – Zone where the requested record changes are done.
• records – Dictionary of additions list or deletions list, or both

of resourceRecordSets. For example:

{‘additions’: [{‘rrdatas’: [‘127.0.0.1’],

‘kind’: ‘dns#resourceRecordSet’, ‘type’: ‘A’, ‘name’: ‘www.example.com.’, ‘ttl’: ‘300’}],
