Connect to Cloud SQL for PostgreSQL using the Cloud SQL Auth proxy

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.

Don't use these instructions to set up the Cloud SQL Auth proxy for a production environment. Also, for more connection options for authenticating and using the proxy, see Connecting using the Cloud SQL Auth proxy.

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 check if billing is enabled on a 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 check if billing is enabled on a 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 Google Cloud 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 PostgreSQL.
  4. Enter myinstance for Instance ID.
  5. Enter a password for the postgres user.
  6. Click Create.

    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.

Debian/Ubuntu

Install the psql client from the package manager:

sudo apt-get update
sudo apt-get install postgresql-client

CentOS/RHEL

Install the psql client from the package manager:

sudo yum install postgresql

openSUSE

Install the psql client from the package manager:

sudo zypper install postgresql

Other platforms

  1. Download the PostgreSQL Core Distribution for your platform from the PostgreSQL Downloads page.
    The Core Distribution includes the psql client.
  2. Install the PostgreSQL database, following the directions on the download page.

Install the Cloud SQL Auth proxy client

The Cloud SQL Auth proxy binary you download depends on your operating system, and whether it uses a 32-bit or 64-bit kernel. Most newer hardware uses a 64-bit kernel. If you're unsure whether your machine is running a 32-bit or 64-bit kernel, then use the uname -a command for Linux or macOS. For Windows, see the Windows documentation.

Linux 64-bit

  1. Download the Cloud SQL Auth proxy:
    wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.amd64 -O cloud_sql_proxy
    
  2. Make the Cloud SQL Auth proxy executable:
    chmod +x cloud_sql_proxy
    

Linux 32-bit

  1. Download the Cloud SQL Auth proxy:
    wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.386 -O cloud_sql_proxy
    
  2. If the wget command is not found, run sudo apt-get install wget and repeat the download command.
  3. Make the Cloud SQL Auth proxy executable:
    chmod +x cloud_sql_proxy
    

macOS 64-bit

  1. Download the Cloud SQL Auth proxy:
    curl -o cloud_sql_proxy https://dl.google.com/cloudsql/cloud_sql_proxy.darwin.amd64
    
  2. Make the Cloud SQL Auth proxy executable:
    chmod +x cloud_sql_proxy
    

macOS 32-bit

  1. Download the Cloud SQL Auth proxy:
    curl -o cloud_sql_proxy https://dl.google.com/cloudsql/cloud_sql_proxy.darwin.386
    
  2. Make the Cloud SQL Auth proxy executable:
    chmod +x cloud_sql_proxy
    

Mac M1

  1. Download the Cloud SQL Auth proxy:
      curl -o cloud_sql_proxy https://dl.google.com/cloudsql/cloud_sql_proxy.darwin.arm64
      
  2. Make the Cloud SQL Auth proxy executable:
      chmod +x cloud_sql_proxy
      

Windows 64-bit

Right-click https://dl.google.com/cloudsql/cloud_sql_proxy_x64.exe and select Save Link As to download the Cloud SQL Auth proxy. Rename the file to cloud_sql_proxy.exe.

Windows 32-bit

Right-click https://dl.google.com/cloudsql/cloud_sql_proxy_x86.exe and select Save Link As to download the Cloud SQL Auth proxy. Rename the file to cloud_sql_proxy.exe.

Cloud SQL Auth proxy Docker image

For convenience, several container images that contain the Cloud SQL Auth proxy are available on GitHub in the Cloud SQL Auth proxy repo. You can pull the latest image to your local machine using Docker with the following command:
docker pull gcr.io/cloudsql-docker/gce-proxy:1.32.0

Other OS

For other operating systems not included here, you can compile the Cloud SQL Auth proxy from source.

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 -instances=INSTANCE_CONNECTION_NAME=tcp:5432

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

.\cloud_sql_proxy.exe -instances=INSTANCE_CONNECTION_NAME=tcp:5432

A message similar to the following appears:

Listening on 127.0.0.1:5432 for INSTANCE_CONNECTION_NAME
Ready for new connections

Run the following command after replacing DB_NAME with the name of the Cloud SQL database:

psql "host=127.0.0.1 port=5432 sslmode=disable dbname=DB_NAME user=postgres"

At the Enter password: prompt, enter the password of your PostgreSQL account.

Verify that the PostgreSQL prompt appears. You have connected to your database using the psql client.

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.
