Connect to Cloud SQL for SQL Server using the Cloud SQL Auth Proxy

MySQL   |  PostgreSQL   |  SQL Server

This page shows you how to connect to Cloud SQL from a local test environment using the Cloud SQL Auth Proxy. The Cloud SQL Auth Proxy provides secure access to your Cloud SQL instance without the need for authorized networks or for configuring SSL. By using the Cloud SQL Auth Proxy, you can connect to your Cloud SQL instance securely.

The instructions on this page are for a test environment only and shouldn't be used for production environments. For more information on the configuration required for production environments, see Use the Cloud SQL Auth Proxy in a production environment and Connect using the Cloud SQL Auth Proxy.

Before you begin

Note: The name you use for your project must be between 4 and 30 characters. When you type the name, the form suggests a project ID, which you can edit. The project ID must be between 6 and 30 characters, with a lowercase letter as the first character. You can use a dash, lowercase letter, or digit for the remaining characters, but the last character cannot be a dash.

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.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud 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 Google Cloud project.

6. Enable the necessary Google Cloud APIs.

   Console

   In the Google Cloud console, go to the APIs page.

   Go to APIs

   Enable the Cloud SQL Admin API.

   gcloud

   Click the following button to open Cloud Shell, which provides command-line access to your Google Cloud resources directly from the browser. Cloud Shell can be used to run the gcloud commands presented throughout this quickstart.

   Open Cloud Shell

   Run the gcloud services enable command as follows using Cloud Shell to enable the APIs required for this quickstart.:

   gcloud services enable sqladmin.googleapis.com

   This command enables the following APIs:

   • Cloud SQL Admin API

Create a Cloud SQL instance

In this quickstart, you use the Google Cloud console. To use the gcloud CLI, cURL, or PowerShell, see Create instances.

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. Click Create instance.
3. Click Choose SQL Server.
4. In the Instance ID field, enter myinstance.
5. In the Password field, enter a password for the sqlserver user.

6. Click Create instance.

   You're returned to the instances list. You can click the new instance right away to see the details, but it won't be available for other operations until it initializes and starts.

   Note: In this example, the instance is created using default settings, including a public IP address.

Debian/Ubuntu

For Debian/Ubuntu, install the applicable SQL Server command-line tools using these instructions.

CentOS/RHEL

For CentOS/RHEL, install the applicable SQL Server command-line tools using these instructions.

openSUSE

For openSUSE, install the applicable SQL Server command-line tools using these instructions.

Other platforms

See the landing page for installing SQL Server, as well as the SQL Server downloads page.

Install the Cloud SQL Auth Proxy client

For installation, see Installing the Cloud SQL Auth Proxy.

Get the instance connection name

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. Click the instance name to open its Overview page.
3. In the Connect to this instance section, copy the Connection name. The connection name is in the format projectID:region:instanceID.

Start the Cloud SQL Auth Proxy

Start the Cloud SQL Auth Proxy in its own terminal so you can monitor its output. Replace INSTANCE_CONNECTION_NAME with the instance connection name you copied in the previous step.

For Linux environments, use this command to launch the Cloud SQL Auth Proxy:

./cloud-sql-proxy INSTANCE_CONNECTION_NAME

In PowerShell on Windows, use this command to launch the Cloud SQL Auth Proxy:

.\cloud-sql-proxy.exe INSTANCE_CONNECTION_NAME

A message similar to the following appears:

Listening on 127.0.0.1:1433 for INSTANCE_CONNECTION_NAME
Ready for new connections

Run the following command, replacing USER_NAME with your SQL Server username.

sqlcmd -S 127.0.0.1 -U USER_NAME

Return to the terminal window where you started the Cloud SQL Auth Proxy. You should see a message similar to the following:

New connection for myInstance

Clean up

To avoid incurring charges to your Google Cloud account for the resources used on this page, follow these steps.
