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")
