Google Cloud Filestore

Warnings

• breaking Python 3.8 and older versions are no longer supported. Ensure your environment uses Python 3.9 or newer.
  Fix: Upgrade your Python environment to version 3.9 or later. The `google-cloud-filestore` library currently supports Python >= 3.9.
• gotcha You must enable the Filestore API for your Google Cloud project before creating or managing instances. This is a common oversight leading to API permission errors.
  Fix: Enable the Filestore API via the Google Cloud Console or using `gcloud services enable file.googleapis.com`.
• gotcha Authentication is crucial. Ensure Application Default Credentials (ADC) are correctly set up, either by running `gcloud auth application-default login` for local development or by configuring service account credentials in production environments.
  Fix: Follow the Google Cloud authentication guide. For local development, `gcloud auth application-default login`. For production, ensure your service account has the necessary IAM roles (e.g., `roles/filestore.viewer` or `roles/filestore.editor`).
• gotcha Filestore instances are zonal or regional. Deploying your Filestore instance in a different zone or region than your Compute Engine VMs or GKE cluster can lead to increased latency and cross-zone networking costs.
  Fix: Always place your Filestore instances in the same zone or region as the compute resources that will access them.
• gotcha The client library logs RPC events using Python's standard logging, and these logs might contain sensitive information. By default, these logs are not handled, so you must configure log handling explicitly.
  Fix: Configure Python's logging module to handle logs from `google.cloud.filestore_v1` if you need to capture them. Exercise caution when storing logs that may contain sensitive data.

Install

• pip install google-cloud-filestore Install latest version

Imports

• CloudFilestoreManagerClient

  from google.cloud.filestore_v1 import CloudFilestoreManagerClient

• filestore_v1

  from google.cloud import filestore_v1

  The primary client class is `CloudFilestoreManagerClient` within the `filestore_v1` module, not a generic 'Client' directly under `google.cloud.filestore`.

Quickstart

This quickstart demonstrates how to initialize the `CloudFilestoreManagerClient` and list existing Filestore instances within a specified Google Cloud project and location. Ensure your `GOOGLE_CLOUD_PROJECT` environment variable is set or replace 'your-project-id' and 'us-central1' with your actual project ID and desired region. Authentication is handled automatically via Application Default Credentials (ADC).

import os
from google.cloud.filestore_v1 import CloudFilestoreManagerClient

project_id = os.environ.get('GOOGLE_CLOUD_PROJECT', 'your-project-id') # Replace with your GCP project ID
location = 'us-central1' # Replace with a suitable region, e.g., 'us-central1'

def list_filestore_instances():
    """Lists all Filestore instances in a given project and location."""
    client = CloudFilestoreManagerClient()
    parent = f"projects/{project_id}/locations/{location}"

    print(f"Listing Filestore instances in {parent}:")
    try:
        # The list_instances method returns a PagedAsyncIterator, which can be iterated directly
        for instance in client.list_instances(parent=parent):
            print(f"  Instance: {instance.name.split('/')[-1]} (State: {instance.state.name}, Tier: {instance.tier.name})")
            print(f"    IP Address: {instance.networks[0].ip_addresses[0] if instance.networks else 'N/A'}")
            print(f"    Capacity: {instance.capacity_gb} GB")
    except Exception as e:
        print(f"Error listing instances: {e}")
