Prerequisites

To follow along with this guide, please make sure to have:

  • created a service account and downloaded the private key (JSON file) for authentication (please check out my detailed guide)

  • installed the Python client library for Google Cloud Storage:

    pip install --upgrade google-cloud-storage

Checking if bucket exists on Google Cloud Storage

To check whether a bucket exists or not on Google Cloud Storage, use the Bucket.exists() method which returns a Boolean:

from google.cloud import storage

path_to_private_key = './gcs-project-354207-099ef6796af6.json'
client = storage.Client.from_service_account_json(json_credentials_path=path_to_private_key)

bucket = storage.Bucket(client, 'example-bucket-skytowner')
bucket.exists()
True

Here, note the following:

  • the credential JSON file for the service account is called gcs-project-354207-099ef6796af6.json and is located in the same directory as this Python script.

  • we are checking if the example-bucket-skytowner bucket exists.
