Connect to Cloud SQL for PostgreSQL from Cloud Shell

This page shows you how to create and connect to a PostgreSQL instance and perform basic SQL operations by using the Google Cloud console and a client. The resources created in this quickstart typically cost less than a dollar, assuming you complete the steps, including the cleanup, in a timely manner.

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

Set up Cloud SQL

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.

Connect to your instance

In this quickstart, we'll use the psql client in Cloud Shell to connect to your instance.

  1. In the Google Cloud console, click the Cloud Shell icon (Cloud Shell icon.) in the upper right corner.

    When Cloud Shell finishes initializing, a message, such as the following one, appears: following one, appears:

    Welcome to Cloud Shell! Type "help" to get started.
    Your Cloud Platform project in this session is set to sample-project.
    Use "gcloud config set project [PROJECT_ID]" to change to a different project.
    username@sample-project:~ (sample-project)$
    
  2. At the Cloud Shell prompt, connect to your Cloud SQL instance. Use the gcloud sql connect command as follows. Replace the instance name if your instance name is different.

    gcloud sql connect myinstance --user=postgres
    
  3. Click Authorize in the message box to authorize Cloud Shell to make API calls.

    A message indicates that your IP is being allowlisted for incoming connections, after which you're prompted to enter your password.

  4. Enter your postgres password.

    The psql prompt appears.

Create a database and upload data

  1. Create a SQL database on your Cloud SQL instance:
    CREATE DATABASE guestbook;
    
  2. Connect to the database by entering the following command and specifying your password.
    \connect guestbook;
    
  3. Insert sample data into the database:
    CREATE TABLE entries (guestName VARCHAR(255), content VARCHAR(255),
                            entryID SERIAL PRIMARY KEY);
    INSERT INTO entries (guestName, content) values ('first guest', 'I got here!');
    INSERT INTO entries (guestName, content) values ('second guest', 'Me too!');
    
  4. Retrieve the data:
    SELECT * FROM entries;
    
    The result is:
      guestname   |   content   | entryid
    --------------+-------------+---------
     first guest  | I got here! |       1
     second guest | Me too!     |       2
    (2 rows)
    postgres=>
    

Clean up

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

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

    Go to Cloud SQL Instances

  2. Select the myinstance instance to open the Instance details page.
  3. In the icon bar at the top of the page, click Delete.
  4. In the Delete instance window, type your instance's name and then click Delete.

Optional cleanup steps

If you're not using the APIs that were enabled as part of this quickstart, you can disable them.

  • APIs that were enabled within this quickstart:
    • Cloud SQL Admin API
  1. In the Google Cloud console, go to the APIs page.

    Go to APIs

  2. Select the Cloud SQL Admin API and then click the Disable API button.
