Quickstart for Cloud SQL for PostgreSQL

This page shows you how to create and connect to a PostgreSQL instance and perform basic SQL operations 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 clean up, in a timely manner.

Before you begin

  1. Sign in to your Google Account.

    If you don't already have one, sign up for a new account.

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

    Go to the project selector page

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

Create an instance

In this procedure, you use the Cloud Console. To use gcloud or cURL, see Creating instances.

  1. Go to the Cloud SQL Instances page in the Google Cloud Console.

    Go to the Cloud SQL Instances page

  2. Select your project and click Continue.

  3. Click Create Instance.

  4. Click PostgreSQL.

  5. Enter myinstance for Instance ID.

  6. Enter a password for the postgres user.

  7. Use the default values for the other fields.

  8. Click Create.

    You are returned to the instances list; you can click into the new instance right away to see the details, but it won't be available until it initializes and starts.

Connect to your instance using the psql client in Cloud Shell

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

    When Cloud Shell finishes initializing, the following appears:

    Welcome to Cloud Shell! Type "help" to get started.
    username@example-id:~$
    

  2. At the Cloud Shell prompt, connect to your Cloud SQL instance:

    gcloud sql connect myinstance --user=postgres
    
  3. 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:
    \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 in this quickstart, follow these steps.

  1. Go to the Cloud SQL Instances page in the Google Cloud Console.
    Go to the Cloud SQL Instances page
  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 myinstance, then click Delete to delete the instance.

    You cannot reuse an instance name for about 7 days after an instance is deleted.

In this quickstart you connected to the instance using Cloud Shell. In most use cases, how you connect depends on your networking configuration, such as:

  • If your Cloud SQL instance has a public or private IP address.
  • If you're connecting from inside Google Cloud (from the same project or from a different project).
  • If you're connecting from outside of Google Cloud.
