Listing buckets

This page shows you how to list the Cloud Storage buckets in a project, which are ordered in the list lexicographically by name. For an overview of buckets, read the Key Terms.

To list the buckets in a project:

Console

Open the Cloud Storage browser in the Google Cloud Console.
Open the Cloud Storage browser

Buckets that are part of the currently selected project appear in the browser list.

gsutil

Use the gsutil ls command:

gsutil ls

The response looks like the following example:

gs://[BUCKET_NAME1]/
gs://[BUCKET_NAME2]/
gs://[BUCKET_NAME3]/
...

C++

namespace gcs = google::cloud::storage;
using ::google::cloud::StatusOr;
[](gcs::Client client) {
  int count = 0;
  gcs::ListBucketsReader bucket_list = client.ListBuckets();
  for (auto&& bucket_metadata : bucket_list) {
    if (!bucket_metadata) {
      throw std::runtime_error(bucket_metadata.status().message());
    }

    std::cout << bucket_metadata->name() << "\n";
    ++count;
  }

  if (count == 0) {
    std::cout << "No buckets in default project\n";
  }
}

C#

For more information, see the Cloud Storage C# API reference documentation . 

private void ListBuckets()
{
    var storage = StorageClient.Create();
    foreach (var bucket in storage.ListBuckets(s_projectId))
    {
        Console.WriteLine(bucket.Name);
    }
}

Go

For more information, see the Cloud Storage Go API reference documentation . 

var buckets []string
it := client.Buckets(ctx, projectID)
for {
	battrs, err := it.Next()
	if err == iterator.Done {
		break
	}
	if err != nil {
		return nil, err
	}
	buckets = append(buckets, battrs.Name)
}

Java

For more information, see the Cloud Storage Java API reference documentation . 

// Include a prefix of bucket-name to reduce search space.
// For more information read https://cloud.google.com/storage/docs/json_api/v1/buckets/list
Page<Bucket> buckets =
    storage.list(BucketListOption.pageSize(100), BucketListOption.prefix(prefix));
for (Bucket bucket : buckets.iterateAll()) {
  // do something with the bucket
}

Node.js

For more information, see the Cloud Storage Node.js API reference documentation . 

// Imports the Google Cloud client library
const {Storage} = require('@google-cloud/storage');

// Creates a client
const storage = new Storage();

// Lists all buckets in the current project
const [buckets] = await storage.getBuckets();
console.log('Buckets:');
buckets.forEach(bucket => {
  console.log(bucket.name);
});

PHP

For more information, see the Cloud Storage PHP API reference documentation . 

use Google\Cloud\Storage\StorageClient;

/**
 * List all Cloud Storage buckets for the current project.
 *
 * @return void
 */
function list_buckets()
{
    $storage = new StorageClient();
    foreach ($storage->buckets() as $bucket) {
        printf('Bucket: %s' . PHP_EOL, $bucket->name());
    }
}

Python

For more information, see the Cloud Storage Python API reference documentation . 

def list_buckets():
    """Lists all buckets."""
    storage_client = storage.Client()
    buckets = storage_client.list_buckets()

    for bucket in buckets:
        print(bucket.name)

Ruby

For more information, see the Cloud Storage Ruby API reference documentation . 

# project_id = "Your Google Cloud project ID"

require "google/cloud/storage"

storage = Google::Cloud::Storage.new project_id: project_id

storage.buckets.each do |bucket|
  puts bucket.name
end

REST APIs

JSON API

  1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials.

  2. Use cURL to call the JSON API with a GET Service request:

    curl -X GET -H "Authorization: Bearer [OAUTH2_TOKEN]" \
  "https://storage.googleapis.com/storage/v1/b?project=[PROJECT_NAME]"

    Where:

    • [OAUTH2_TOKEN] is the access token you generated in Step 1.
    • [PROJECT_NAME] is the name of the project containing the buckets you want to list. For example, my-project.

    You can use a prefix=[PREFIX] query string parameter to limit results to buckets that have the specified prefix.

XML API

  1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials.

  2. Use cURL to call the XML API with a GET Service request:

    curl -X GET -H "Authorization: Bearer [OAUTH2_TOKEN]" \
  -H "x-goog-project-id: [PROJECT_NAME]" \
  "https://storage.googleapis.com"

    Where:

    • [OAUTH2_TOKEN] is the access token you generated in Step 1.
    • [PROJECT_NAME] is the name of the project containing the buckets you want to list. For example, my-project.

    You can use a prefix=[PREFIX] query string parameter to limit results to buckets that have the specified prefix.
