Creating storage buckets

This page shows you how to create Cloud Storage buckets. For an overview of buckets, read the Key Terms. If not otherwise specified in your request, buckets are created in the US multi-region and have a default storage class of Standard Storage.

To create a new storage bucket:

Console

  1. In the Google Cloud Console, go to the Cloud Storage Browser page.

    Go to Browser

  2. Click Create bucket.
  3. On the Create a bucket page, enter your bucket information. To go to the next step, click Continue.
    • For Name your bucket, enter a name that meets the bucket naming requirements.
    • For Choose where to store your data, select a Location type and Location option where the bucket data will be permanently stored.
    • For Choose a default storage class for your data, select a storage class for the bucket. The default storage class is assigned by default to all objects uploaded to the bucket.

      Note: The Monthly cost estimate panel in the right pane estimates the bucket's monthly costs based on your selected storage class and location, as well as your expected data size and operations.

    • For Choose how to control access to objects, select whether or not your bucket enforces public access prevention, and select an Access control model for your bucket's objects.

      Note: If public access prevention is already enforced by your project's organization policy, the Prevent public access toggle is locked.

    • For Advanced settings (optional), add bucket labels, set a retention policy, and choose an encryption method.
  4. Click Create.

To learn how to get detailed error information about failed operations in the Cloud Storage browser, see Troubleshooting.

gsutil

Use the gsutil mb command:

gsutil mb gs://BUCKET_NAME

Where:

  • BUCKET_NAME is the name you want to give your bucket, subject to naming requirements. For example, my-bucket.

If the request is successful, the command returns the following message:

Creating gs://BUCKET_NAME/...

Set the following optional flags to have greater control over the creation of your bucket:

  • -p: Specify the project with which your bucket will be associated. For example, my-project.
  • -c: Specify the default storage class of your bucket. For example, NEARLINE.
  • -l: Specify the location of your bucket. For example, US-EAST1.
  • -b: Enable uniform bucket-level access for your bucket.

For example:

  gsutil mb -p PROJECT_ID -c STORAGE_CLASS -l BUCKET_LOCATION -b on gs://BUCKET_NAME

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. Create a .json file that contains the settings for the bucket, which must include a name for the bucket. See the Buckets:Insert documentation for a complete list of settings. The following are common settings to include:
    3. {
  "name": "BUCKET_NAME",
  "location": "BUCKET_LOCATION",
  "storageClass": "STORAGE_CLASS",
  "iamConfiguration": {
    "uniformBucketLevelAccess": {
      "enabled": true
    },
  }
}

    Where:

    • BUCKET_NAME is the name you want to give your bucket, subject to naming requirements. For example, my-bucket.
    • BUCKET_LOCATION is the location where you want to store your bucket's object data. For example, US-EAST1.
    • STORAGE_CLASS is the default storage class of your bucket. For example, NEARLINE.
  3. Use cURL to call the JSON API: 
    curl -X POST --data-binary @JSON_FILE_NAME.json \
     -H "Authorization: Bearer OAUTH2_TOKEN" \
     -H "Content-Type: application/json" \
     "https://storage.googleapis.com/storage/v1/b?project=PROJECT_ID"

    Where:

    • JSON_FILE_NAME is name of the JSON file you created in Step 2.
    • OAUTH2_TOKEN is the access token you generated in Step 1.
    • PROJECT_ID is the ID of the project with which your bucket will be associated. For example, my-project.

XML API

  1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials.
  2. Create a .xml file that contains the following information:
    3. <CreateBucketConfiguration>
   <LocationConstraint>BUCKET_LOCATION</LocationConstraint>
   <StorageClass>STORAGE_CLASS</StorageClass>
</CreateBucketConfiguration>

    Where:

    • BUCKET_LOCATION is the location where you want to store your bucket's object data. For example, US-EAST1.
    • STORAGE_CLASS is the default storage class of your bucket. For example, NEARLINE.
  3. Use cURL to call the XML API: 
    curl -X PUT --data-binary @XML_FILE_NAME.xml \
     -H "Authorization: Bearer OAUTH2_TOKEN" \
     -H "x-goog-project-id: PROJECT_ID" \
     "https://storage.googleapis.com/BUCKET_NAME"

    Where:

    • XML_FILE_NAME is name of the XML file you created in Step 2.
    • OAUTH2_TOKEN is the access token you generated in Step 1.
    • PROJECT_ID is the ID of the project with which your bucket will be associated. For example, my-project.
    • BUCKET_NAME is the name you want to give your bucket, subject to naming requirements. For example, my-bucket.
