I'm trying to create kubernetes cluster on google cloud platform through python (3.7) using google-cloud-container module.

Created kubernetes cluster through google cloud platform and was able to successfully retrieve details for that cluster using google-cloud container (python module).

I'm trying now to create kubernetes cluster through this module. I created a JSON file with required key values and passed it as parameter, but i'm getting errors. Would appreciate if provided a sample code for creating kubernetes cluster in google cloud platform. Thank you in advance.

from google.oauth2 import service_account
from google.cloud import container_v1



class GoogleCloudKubernetesClient(object):

    def __init__(self, file, project_id, project_name, zone, cluster_id):
        credentials = service_account.Credentials.from_service_account_file(
            filename=file)
        self.client = container_v1.ClusterManagerClient(credentials=credentials)
        self.project_id = project_id
        self.zone = zone

    def create_cluster(self, cluster):
        print(cluster)
        response = self.client.create_cluster(self.project_id, self.zone, cluster=cluster)
        print(f"response for cluster creation: {response}")
