How Do I Build a Mysql Index Grant With Pulumi?

Introduction

In this guide, we will walk through the process of creating a MySQL index grant using Pulumi. We will use Pulumi’s AWS provider to manage the MySQL database and grant the necessary privileges.

Step-by-Step Explanation

1. Set up Pulumi and AWS Provider

First, ensure you have Pulumi installed and configured with your AWS credentials. You can follow the installation guide if you haven’t done this yet.

2. Create a New Pulumi Project

Create a new Pulumi project using TypeScript:

pulumi new aws-typescript

3. Define the MySQL Database

In your index.ts file, define the MySQL database resource:

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

const db = new aws.rds.Instance("mydb", {
    engine: "mysql",
    instanceClass: aws.rds.InstanceTypes.T2_Micro,
    allocatedStorage: 20,
    dbName: "mydatabase",
    username: "admin",
    password: "password123",
    skipFinalSnapshot: true,
});

4. Create the MySQL User

Next, create a MySQL user and grant index privileges:

const dbUser = new aws.rds.User("dbUser", {
    userName: "indexUser",
    password: "userpassword",
    database: db.name,
});

5. Grant Index Privileges

Finally, grant the index privileges to the user:

const grant = new aws.rds.Grant("indexGrant", {
    user: dbUser.userName,
    database: db.name,
    privileges: ["INDEX"],
});

6. Deploy the Stack

Deploy your Pulumi stack:

pulumi up

Conclusion

In this guide, we created a MySQL database, user, and granted index privileges using Pulumi. This setup ensures that the specified user has the necessary permissions to manage indexes in the MySQL database.

Full Code Example

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

const db = new aws.rds.Instance("mydb", {
    engine: "mysql",
    instanceClass: aws.rds.InstanceTypes.T2_Micro,
    allocatedStorage: 20,
    dbName: "mydatabase",
    username: "admin",
    password: "password123",
    skipFinalSnapshot: true,
});

const dbUser = new aws.iam.User("dbUser", {
    name: "indexUser",
});

const dbUserPolicy = new aws.iam.Policy("dbUserPolicy", {
    policy: pulumi.output(db.name).apply(dbName => JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Action: [
                    "rds-db:connect",
                    "rds-db:grant",
                    "rds-db:revoke"
                ],
                Effect: "Allow",
                Resource: \`arn:aws:rds-db:*:*:dbuser/\${dbName}/indexUser\`
            }
        ]
    }))
});

const dbUserPolicyAttachment = new aws.iam.UserPolicyAttachment("dbUserPolicyAttachment", {
    user: dbUser.name,
    policyArn: dbUserPolicy.arn,
});
