Google Container Driver Documentation¶
Google Container Platform is a Kubernetes hosting service, provided by Google. Docker-native tools and elastic hosts make deploying on Google Cloud as easy as running Docker on your laptop. There is no special software to install or configure. Mix Kubernetes containers with container-native Linux to extend the benefits of containerization to legacy applications and stateful services.
Examples¶
Additional example code can be found in the “demos” directory of Libcloud here: https://github.com/apache/libcloud/blob/trunk/demos/gce_demo.py
1. Getting Driver with Service Account authentication¶
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver
ComputeEngine = get_driver(Provider.GCE)
# Note that the 'PEM file' argument can either be the JSON format or
# the P12 format.
driver = ComputeEngine('your_service_account_email', 'path_to_pem_file',
project='your_project_id')

GKEContainerDriver
(user_id, key=None, datacenter=None, project=None, auth_type=None, scopes=None, credential_file=None, host=None, port=443, **kwargs)[source]¶ GKE Container Driver class.
This is the primary driver for interacting with Google Container Engine. It contains all of the standard libcloud methods, plus additional ex_* methods for more features.
Note that many methods allow either objects or strings (or lists of objects/strings). In most cases, passing strings instead of objects will result in additional GKE API calls.
Parameters: - user_id (
str
) – The email address (for service accounts) or Client ID (for installed apps) to be used for authentication. - key (
str
) – The RSA Key (for service accounts) or file path containing key or Client Secret (for installed apps) to be used for authentication. - datacenter (
str
) – The name of the datacenter (zone) used for operations. - project (
str
) – Your GKE project name. (required) - auth_type (
str
) – Accepted values are “SA” or “IA” or “GKE” (“Service Account” or “Installed Application” or “GKE” if libcloud is being used on a GKE instance with service account enabled). If not supplied, auth_type will be guessed based on value of user_id or if the code is being executed in a GKE instance. - scopes (
list
) – List of authorization URLs. Default is empty and grants read/write to Compute, Storage, DNS. - credential_file (
str
) – Path to file for caching authentication information used by GKEConnection.

deploy_container
(name, image, cluster=None, parameters=None, start=True)¶ Deploy an installed container image. In kubernetes this deploys a single container Pod. https://cloud.google.com/container-engine/docs/pods/single-container
