Cloud SQL Basics
Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL, and SQL Server. It automates time-consuming tasks like patches, updates, backups, and replicas, while providing high performance and availability for your applications.
Prerequisites
Ensure you have the necessary IAM permissions to create and manage Cloud SQL
instances. The Cloud SQL Admin (roles/cloudsql.admin) role provides full
access to Cloud SQL resources.
Quick Start (PostgreSQL)
-
Enable the API:
-
Create an Instance:
-
Set a password for the default user:
Because this is a Cloud SQL for PostgreSQL instance, the default admin user is
postgres: -
Create a database:
-
Get the instance connection name:
You need the instance connection name (which is formatted as
PROJECT_ID:REGION:INSTANCE_NAME) to connect using the Cloud SQL Auth Proxy. Retrieve it with the following command: -
Connect to the instance:
The Cloud SQL Auth Proxy must be running to be able to connect to the instance. In a separate terminal, start the proxy using the connection name:
With the proxy running, connect using
psqlin another terminal:
