How Do I Build an AWS SQS Queuepolicy With Pulumi?

Building an AWS SQS Queue Policy with Pulumi

In this guide, we will walk through the steps to create an AWS SQS Queue Policy using Pulumi. AWS SQS (Simple Queue Service) allows you to decouple and scale microservices, distributed systems, and serverless applications. A queue policy is used to control access to the SQS queue.

Step-by-Step Explanation

1. Install Pulumi and AWS SDK: Ensure you have Pulumi and the AWS SDK installed. You can install Pulumi using npm:

   npm install -g pulumi
   

   Install the AWS SDK for JavaScript:

   npm install @pulumi/aws
   

2. Create a New Pulumi Project: Initialize a new Pulumi project.

   pulumi new aws-typescript
   

3. Define the SQS Queue: In your index.ts file, define the SQS queue.

   import * as aws from "@pulumi/aws";
   
   const queue = new aws.sqs.Queue("my-queue", {
       visibilityTimeoutSeconds: 30,
   });
   

4. Create the Queue Policy: Define the policy for the SQS queue. This policy will specify who has access to the queue and what actions they can perform.

   const policy = new aws.sqs.QueuePolicy("my-queue-policy", {
       queueUrl: queue.url,
       policy: JSON.stringify({
           Version: "2012-10-17",
           Statement: [
               {
                   Effect: "Allow",
                   Principal: "*",
                   Action: "sqs:SendMessage",
                   Resource: queue.arn,
               },
           ],
       }),
   });
   

5. Deploy the Stack: Run pulumi up to deploy the stack.

   pulumi up
   

Summary

By following these steps, you have created an AWS SQS queue and attached a policy to it using Pulumi. This policy allows any principal to send messages to the queue. You can customize the policy as needed to fit your security requirements.

Full Code Example

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

const queue = new aws.sqs.Queue("my-queue", {
    visibilityTimeoutSeconds: 30,
});

const policy = new aws.sqs.QueuePolicy("my-queue-policy", {
    queueUrl: queue.url,
    policy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Effect: "Allow",
                Principal: "*",
                Action: "sqs:SendMessage",
                Resource: queue.arn,
            },
        ],
    }),
});

export const queueUrl = queue.url;
export const queueArn = queue.arn;
