How Do I Build a GCP SQL Database Instance With Pulumi?

Introduction

This guide aims to provide a comprehensive walkthrough on how to create a SQL database instance on Google Cloud using Pulumi. Pulumi is an infrastructure as code tool that allows you to define and manage cloud resources using familiar programming languages. In this guide, we will focus on setting up a SQL instance and a database within that instance. This is particularly useful for applications that require a robust, managed relational database service.

Step-by-Step Guide

1. Setup Pulumi and Google Cloud Provider: Before starting, ensure you have Pulumi installed and configured with Google Cloud credentials. This will allow Pulumi to interact with your Google Cloud account.

2. Define a Google Cloud SQL Instance: Use Pulumi and the Google Cloud Provider to define a SQL instance. The instance will be configured with specific settings such as the database version, region, and machine type.

3. Create a Database within the SQL Instance: Once the SQL instance is defined, create a database within this instance. You will specify properties like the database name, character set, and collation.

4. Export the Connection Information: Finally, export the instance connection name, which can be used by applications to connect to the database.

Here’s the code that accomplishes these steps:

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

// Define a Google Cloud SQL instance
const sqlInstance = new gcp.sql.DatabaseInstance("sqlInstance", {
    name: "my-sql-instance",
    databaseVersion: "MYSQL_8_0",
    region: "us-central1",
    settings: {
        tier: "db-f1-micro",
        backupConfiguration: {
            enabled: true,
        },
        ipConfiguration: {
            ipv4Enabled: true,
        },
    },
});

// Define a database within the SQL instance
const sqlDatabase = new gcp.sql.Database("sqlDatabase", {
    name: "mydatabase",
    instance: sqlInstance.name,
    charset: "utf8",
    collation: "utf8_general_ci",
});

// Export the instance connection name
export const instanceConnectionName = sqlInstance.connectionName;

Summary

In conclusion, this guide detailed the process of setting up a Google Cloud SQL instance and a database within that instance using Pulumi. By following the steps outlined, you can efficiently create a managed SQL database service tailored to your application’s needs. This setup not only simplifies database management but also leverages the scalability and reliability of Google Cloud.
