Upload objects from a file system

This page shows you how to upload objects to your Cloud Storage bucket from your local file system. An uploaded object consists of the data you want to store along with any associated metadata. For a conceptual overview, including how to choose the optimal upload method based on your file size, see Uploads and downloads.

For instructions on uploading from memory, see Upload objects from memory.

Required roles

To get the permissions that you need to upload objects to a bucket, ask your administrator to grant you the Storage Object User (roles/storage.objectUser) IAM role on the bucket. This predefined role contains the permissions required to upload an object to a bucket. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

  • storage.objects.create
  • storage.objects.delete
    • This permission is only required for uploads that overwrite an existing object.
  • storage.objects.get
    • This permission is only required if you plan on using the Google Cloud CLI to perform the tasks on this page.
  • storage.objects.list
    • This permission is only required if you plan on using the Google Cloud CLI to perform the tasks on this page. This permission is also required if you want to use the Google Cloud console to verify the objects you've uploaded.

If you plan on using the Google Cloud console to perform the tasks on this page, you'll also need the storage.buckets.list permission, which is not included in the Storage Object User (roles/storage.objectUser) role. To get this permission, ask your administrator to grant you the Storage Admin (roles/storage.admin) role on the project.

You can also get these permissions with other predefined roles or custom roles.

For information about granting roles on buckets, see Use IAM with buckets.

Upload an object to a bucket

Complete the following steps to upload an object to a bucket:

Console

  1. In the Google Cloud console, go to the Cloud Storage Buckets page.

    Go to Buckets

  2. In the list of buckets, click the name of the bucket that you want to upload an object to.

  3. In the Objects tab for the bucket, either:

    • Drag files from your desktop or file manager to the main pane in the Google Cloud console.

    • Click the Upload Files button, select the files you want to upload in the dialog that appears, and click Open.

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

Command line

Use the gcloud storage cp command:

gcloud storage cp OBJECT_LOCATION gs://DESTINATION_BUCKET_NAME

Where:

  • OBJECT_LOCATION is the local path to your object. For example, Desktop/dog.png.

  • DESTINATION_BUCKET_NAME is the name of the bucket to which you are uploading your object. For example, my-bucket.

If successful, the response looks like the following example:

Completed files 1/1 | 164.3kiB/164.3kiB

You can set fixed-key and custom object metadata as part of your object upload by using command flags.

Terraform

You can use a Terraform resource to upload an object. Either content or source must be specified.

# Create a text object in Cloud Storage

REST APIs

JSON API

The JSON API distinguishes between media uploads, in which only object data is included in the request, and JSON API multipart uploads, in which both object data and object metadata are included in the request.

Media upload (a single-request upload without object metadata)

  1. Have gcloud CLI installed and initialized, which lets you generate an access token for the Authorization header.

  2. Use cURL to call the JSON API with a POST Object request:

    curl -X POST --data-binary @OBJECT_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: OBJECT_CONTENT_TYPE" \
        "https://storage.googleapis.com/upload/storage/v1/b/BUCKET_NAME/o?uploadType=media&name=OBJECT_NAME"

    Where:

    • OBJECT_LOCATION is the local path to your object. For example, Desktop/dog.png.
    • OBJECT_CONTENT_TYPE is the content type of the object. For example, image/png.
    • BUCKET_NAME is the name of the bucket to which you are uploading your object. For example, my-bucket.
    • OBJECT_NAME is the URL-encoded name you want to give your object. For example, pets/dog.png, URL-encoded as pets%2Fdog.png.

JSON API multipart upload (a single-request upload that includes object metadata)

  1. Have gcloud CLI installed and initialized, which lets you generate an access token for the Authorization header.

  2. Create a multipart/related file that contains the following information:

    --BOUNDARY_STRING
    Content-Type: application/json; charset=UTF-8
    
    OBJECT_METADATA
    
    --BOUNDARY_STRING
    Content-Type: OBJECT_CONTENT_TYPE
    
    OBJECT_DATA
    --BOUNDARY_STRING--

    Where:

    • BOUNDARY_STRING is a string you define that identifies the different parts of the multipart file. For example, separator_string.
    • OBJECT_METADATA is metadata you want to include for the file, in JSON format. At a minimum, this section should include a name attribute for the object, for example {"name": "myObject"}.
    • OBJECT_CONTENT_TYPE is the content type of the object. For example, text/plain.
    • OBJECT_DATA is the data for the object.

    For example:

    --separator_string
    Content-Type: application/json; charset=UTF-8
    
    {"name":"my-document.txt"}
    
    --separator_string
    Content-Type: text/plain
    
    This is a text file.
    --separator_string--
  3. Use cURL to call the JSON API with a POST Object request:

    curl -X POST --data-binary @MULTIPART_FILE_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: multipart/related; boundary=BOUNDARY_STRING" \
        -H "Content-Length: MULTIPART_FILE_SIZE" \
        "https://storage.googleapis.com/upload/storage/v1/b/BUCKET_NAME/o?uploadType=multipart"

    Where:

    • MULTIPART_FILE_LOCATION is the local path to the multipart file you created in step 2. For example, Desktop/my-upload.multipart.
    • BOUNDARY_STRING is the boundary string you defined in Step 2. For example, my-boundary.
    • MULTIPART_FILE_SIZE is the total size, in bytes, of the multipart file you created in Step 2. For example, 2000000.
    • BUCKET_NAME is the name of the bucket to which you are uploading your object. For example, my-bucket.

If the request succeeds, the server returns the HTTP 200 OK status code along with the file's metadata.

XML API

  1. Have gcloud CLI installed and initialized, which lets you generate an access token for the Authorization header.

  2. Use cURL to call the XML API with a PUT Object request:

    curl -X PUT --data-binary @OBJECT_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: OBJECT_CONTENT_TYPE" \
        "https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME"

    Where:

    • OBJECT_LOCATION is the local path to your object. For example, Desktop/dog.png.
    • OBJECT_CONTENT_TYPE is the content type of the object. For example, image/png.
    • BUCKET_NAME is the name of the bucket to which you are uploading your object. For example, my-bucket.
    • OBJECT_NAME is the URL-encoded name you want to give your object. For example, pets/dog.png, URL-encoded as pets%2Fdog.png.

You can set additional object metadata as part of your object upload in the headers of the request in the same way the previous example sets Content-Type. When working with the XML API, metadata can only be set at the time the object is written, such as when uploading, copying, or replacing the object. For more information, see Editing object metadata.
