How Do I Create a GCP SQL User With Pulumi?

Introduction

Creating a SQL user in Google Cloud SQL is a fundamental task for managing database access and security. This guide will walk you through the process of setting up a SQL user in Google Cloud SQL using Pulumi, a modern infrastructure as code platform. By following this tutorial, you will be able to define a Cloud SQL instance and create a user for that instance, ensuring your database is ready for secure connections.

Step-by-Step Guide

In this example, we will create a SQL user in Google Cloud SQL using Pulumi. We will define a Cloud SQL instance and then create a user for that instance. This involves specifying the instance details and the user properties such as username and password.

Key Points:

• We will use the @pulumi/gcp package to interact with Google Cloud resources.
• We will define a Cloud SQL instance.
• We will create a SQL user for the defined instance.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

// Create a Cloud SQL instance
const instance = new gcp.sql.DatabaseInstance("instance", {
    databaseVersion: "MYSQL_8_0",
    settings: {
        tier: "db-f1-micro",
    },
});

// Create a SQL user for the instance
const user = new gcp.sql.User("user", {
    instance: instance.name,
    name: "myuser",
    password: "mypassword",  // Ensure this is securely managed in a real scenario
});

export const instanceConnectionName = instance.connectionName;
export const userName = user.name;
export const userPassword = user.password;  // Do not export sensitive information in a real scenario

Explanation

1. Import Packages: We begin by importing the necessary Pulumi and GCP packages to interact with Google Cloud resources.
2. Create Cloud SQL Instance: A Cloud SQL instance named instance is created with MySQL version 8.0 and a small instance tier (db-f1-micro).
3. Create SQL User: A SQL user named myuser is created with a specified password for the instance.
4. Export Details: The connection name of the instance and the username are exported for reference. Note that sensitive information like passwords should be handled securely in a production environment.

Conclusion

This setup will provision a Cloud SQL instance and create a user for that instance, enabling you to connect to the database securely. Always ensure that sensitive information such as passwords is managed properly to maintain the security of your database environment. By using Pulumi, you can automate and manage your infrastructure efficiently, ensuring consistency and reliability in your deployments.
