Hosting a static website using HTTP

This tutorial describes how to configure a Cloud Storage bucket to host a static website for a domain you own. Static web pages can contain client-side technologies such as HTML, CSS, and JavaScript. They cannot contain dynamic content such as server-side scripts like PHP.

This tutorial shows you how to serve content over HTTP. For a tutorial that uses HTTPS, see Hosting a static website.

For examples and tips on static web pages, including how to host static assets for a dynamic website, see the Static Website page.

Objectives

In this tutorial you will:

  • Point your domain to Cloud Storage by using a CNAME record.
  • Create a bucket that is linked to your domain.
  • Upload and share your site's files.
  • Test the website.

Costs

This tutorial uses the following billable component of Google Cloud:

  • Cloud Storage

See the Monitoring your storage charges tip for details on what charges may be incurred when hosting a static website, and see the Pricing page for details on Cloud Storage costs.

Before you begin

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

  3. Make sure that billing is enabled for your Cloud project. Learn how to confirm that billing is enabled for your project.

  4. In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

  5. Make sure that billing is enabled for your Cloud project. Learn how to confirm that billing is enabled for your project.

  6. Have a domain that you own or manage. If you don't have an existing domain, there are many services through which you can register a new domain, such as Google Domains.

    This tutorial uses the domain example.com.

  7. Verify that you own or manage the domain that you will be using. Make sure you are verifying the top-level domain, such as example.com, and not a subdomain, such as www.example.com.

    Note: If you own the domain you are associating to a bucket, you might have already performed this step in the past. If you purchased your domain through Google Domains, verification is automatic.

Connecting your domain to Cloud Storage

To connect your domain to Cloud Storage, create a CNAME record through your domain registration service. A CNAME record is a type of DNS record. It directs traffic that requests a URL from your domain to the resources you want to serve, in this case objects in your Cloud Storage buckets. For www.example.com, the CNAME record might contain the following information:

NAME                  TYPE     DATA
www                   CNAME    c.storage.googleapis.com.

For more information about CNAME redirects, see URI for CNAME aliasing.

To connect your domain to Cloud Storage:

  1. Create a CNAME record that points to c.storage.googleapis.com..

    Your domain registration service should have a way for you to administer your domain, including adding a CNAME record. For example, if you use Google Domains, instructions for adding resource records can be found on the Google Domains Help page.

Creating a bucket

Create a bucket whose name matches the CNAME you created for your domain.

For example, if you added a CNAME record pointing from the www subdomain of example.com to c.storage.googleapis.com., then create a bucket with the name "www.example.com".

To create a bucket:

Console

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

    Go to Browser

  2. Click Create bucket to open the bucket creation form.

  3. Enter your bucket information and click Continue to complete each step:

    • The Name of your bucket, which matches the hostname associated with your CNAME record.

    • Select the Location type and Location of your bucket. For example, Region and us-east1.

    • Select Standard Storage for the Storage class.

    • Select Uniform for Access control.

  4. Click Create.

If successful, you are taken to the bucket's page with the text "There are no live objects in this bucket."

gsutil

Use the gsutil mb command:

gsutil mb gs://www.example.com

If successful, the command returns:

Creating gs://www.example.com/...

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 assigns your website name to the name property:

    {
      "name": "www.example.com"
    }
  3. Use cURL to call the JSON API. For www.example.com:

    curl -X POST --data-binary @website-bucket-name.json \
      -H "Authorization: Bearer ya29.AHES6ZRVmB7fkLtd1XTmq6mo0S1wqZZi3-Lh_s-6Uw7p8vtgSwg" \
      -H "Content-Type: application/json" \
      "https://storage.googleapis.com/storage/v1/b?project=my-static-website"

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 to create a bucket with your website name. For www.example.com:

    curl -X PUT \
      -H "Authorization: Bearer ya29.AHES6ZRVmB7fkLtd1XTmq6mo0S1wqZZi3-Lh_s-6Uw7p8vtgSwg" \
      -H "x-goog-project-id: my-static-website" \
      "https://storage.googleapis.com/www.example.com"

Uploading your site's files

To add to your bucket the files you want your website to serve:

Console

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

    Go to Browser

  2. In the list of buckets, click on the name of the bucket that you created.

  3. Click the Upload files button in the Objects tab.

  4. In the file dialog, browse to the desired file and select it.

After the upload completes, you should see the file name along with file information displayed in the bucket.

gsutil

Use the gsutil cp command to copy files to your bucket. For example, to copy the file index.html from its current location Desktop:

gsutil cp Desktop/index.html gs://www.example.com

If successful, the command returns:

Copying file://Desktop/index.html [Content-Type=text/html]...
Uploading   gs://www.example.com/index.html:       0 B/2.58 KiB
Uploading   gs://www.example.com/index.html:       2.58 KiB/2.58 KiB

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 following information:

    {
      "bindings":[
        {
          "role": "roles/storage.objectViewer",
          "members":["allUsers"]
        }
      ]
    }
  3. Use cURL to call the JSON API with a PUT Bucket request:

    curl -X PUT --data-binary @JSON_FILE_NAME.json \
      -H "Authorization: Bearer OAUTH2_TOKEN" \
      -H "Content-Type: application/json" \
      "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/iam"

    Where:

    • JSON_FILE_NAME is the name of the file you created in Step 2.
    • OAUTH2_TOKEN is the access token you created in Step 1.
    • BUCKET_NAME is the name of the bucket whose objects you want to make public. For example, my-bucket.

XML API

Making all objects in a bucket publicly readable is not supported by the XML API. Use gsutil or the JSON API instead.

You can make groups of objects in your bucket publicly accessible, but generally, making all files in your bucket publicly accessible is easier and faster.

Visitors receive a http 403 response code when requesting the URL for a non-public or non-existent file. See the next section for information on how to add an error page that uses a http 404 response code.

Recommended: Assigning specialty pages

You can assign an index page suffix, which is controlled by the MainPageSuffix property and a custom error page, which is controlled by the NotFoundPage property. Assigning either is optional, but without an index page, nothing is served when users access your top-level site, for example, http://www.example.com. For more information, see Website configuration examples.

In the following sample, the MainPageSuffix is set to index.html and NotFoundPage is set to 404.html:

Console

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

    Go to Browser

  2. In the list of buckets, find the bucket you created.

  3. Click the Bucket overflow menu () associated with the bucket and select Edit website configuration.

  4. In the website configuration dialog, specify the main page and error page.

  5. Click Save.

gsutil

Use the gsutil web set command to set the MainPageSuffix property with the -m flag and the NotFoundPage with the -e flag:

gsutil web set -m index.html -e 404.html gs://www.example.com

If successful, the command returns:

Setting website config on gs://www.example.com/...

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 sets the mainPageSuffix and notFoundPage properties in a website object to the desired pages:

    {
      "website":{
        "mainPageSuffix": "index.html",
        "notFoundPage": "404.html"
      }
    }
  3. Use cURL to call the JSON API with a PATCH Bucket request. For www.example.com:

    curl -X PATCH --data-binary @web-config.json \
      -H "Authorization: Bearer ya29.AHES6ZRVmB7fkLtd1XTmq6mo0S1wqZZi3-Lh_s-6Uw7p8vtgSwg" \
      -H "Content-Type: application/json" \
      "https://storage.googleapis.com/storage/v1/b/www.example.com"

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 sets the MainPageSuffix and NotFoundPage elements in a WebsiteConfiguration element to the desired pages:

    <WebsiteConfiguration>
      <MainPageSuffix>index.html</MainPageSuffix>
      <NotFoundPage>404.html</NotFoundPage>
    </WebsiteConfiguration>
  3. Use cURL to call the XML API with a PUT Bucket request and websiteConfig query string parameter. For www.example.com:

    curl -X PUT --data-binary @web-config.xml \
      -H "Authorization: Bearer ya29.AHES6ZRVmB7fkLtd1XTmq6mo0S1wqZZi3-Lh_s-6Uw7p8vtgSwg" \
      https://storage.googleapis.com/www.example.com?websiteConfig

Testing the website

Verify that content is served from the bucket by requesting the domain name in a browser. You can do this with a path to an object or with just the domain name, if you set the MainPageSuffix property.

For example, if you have an object named test.html stored in a bucket named www.example.com, check that it's accessible by going to www.example.com/test.html in your browser.

Clean up

After you finish the tutorial, you can clean up the resources that you created so that they stop using quota and incurring charges. The following sections describe how to delete or turn off these resources.

Deleting the project

The easiest way to eliminate billing is to delete the project that you created for the tutorial.

To delete the project:

  1. In the Cloud Console, go to the Manage resources page.

    Go to Manage resources

  2. In the project list, select the project that you want to delete, and then click Delete.
  3. In the dialog, type the project ID, and then click Shut down to delete the project.

Deleting the bucket

If you do not want to delete the entire project, delete the bucket that you used for hosting your website:

Console

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

    Go to Browser

  2. Select the checkbox associated with www.example.com.

  3. Click Delete.

  4. In the overlay window that appears, confirm you want to delete the bucket and its contents by clicking Delete.

gsutil

Use the gsutil rm command with the -r flag to delete the bucket and the contents inside of it:

gsutil rm -r gs://www.example.com

The response looks like the following example:

Removing gs://www.example.com/...
