# Connect to Google Cloud Storage

This topic describes how to connect to [Google Cloud Storage (GCS)](https://cloud.google.com/storage/) from Domino. You must have network connectivity between GCS and your Domino deployment.

The easiest way to connect to a GCS instance from Domino is to create a Domino Data Source as described below.

## Create a Google Cloud Storage Data Source

1. From the navigation pane, click **Data > Data Sources**.

2. Click **Create a Data Source**.

3. In the New Data Source window, from **Select Data Store**, select **GCS** for **Google Cloud Storage**.

4. Enter the name of the **Bucket**.

5. Enter the **Data Source Name**.

   <Note>
     Although Google Cloud allows storage bucket names that include underscores, Domino only allows lowercase letters, numbers, periods, and hyphens.
   </Note>

6. Optional: Enter a **Description** to explain the purpose of the Data Source to others.

7. Click **Next**.

8. Copy the **Private Key (JSON format)**. See [creating a service account](https://cloud.google.com/docs/authentication/getting-started#creating_a_service_account) for instructions about creating a service account and downloading the JSON credentials file. You must copy the entire content of the file. The Domino secret store backed by HashiCorp Vault securely stores the credentials.

9. Click **Test Credentials**.

10. If the Data Source authenticates, click **Next**.

11. Select who can view and use the Data Source in projects.

12. Click **Finish Setup**.
