Using aws elasticbeanstalk with mq

Question

Pulumi · Accepted Answer

To integrate AWS Elastic Beanstalk with Amazon MQ, you can follow these steps:

1. Define an Amazon MQ Broker using `aws.mq.Broker`. This broker will manage message queues on your behalf.
2. Define an Elastic Beanstalk application using `aws.elasticbeanstalk.Application` and an environment for the application using `aws.elasticbeanstalk.Environment`.
3. Configure the environment to communicate with the Amazon MQ broker. This typically involves setting environment variables or passing configuration information to your application running on Elastic Beanstalk, so it knows how to connect to the MQ broker.

The following Pulumi TypeScript program demonstrates this integration. It creates an Amazon MQ broker, an Elastic Beanstalk application, and an environment with the necessary settings:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as aws from '@pulumi/aws';

// Create an Amazon MQ Broker
const mqBroker = new aws.mq.Broker("myMqBroker", {
    brokerName: "my-mq-broker",
    engineType: "ActiveMQ",
    engineVersion: "5.15.0",
    hostInstanceType: "mq.t2.micro",
    user: {
        username: "mq_user",
        password: "mq_password",
    },
    applyImmediately: true,
    publiclyAccessible: true,
});

// Step 1: Create an Elastic Beanstalk Application
const app = new aws.elasticbeanstalk.Application("myApp", {
    name: "my-application",
    description: "My Elastic Beanstalk Application",
});

// Step 2: Create an Elastic Beanstalk Environment for the application
const env = new aws.elasticbeanstalk.Environment("myEnv", {
    application: app.name,
    solutionStackName: "64bit Amazon Linux 2 v3.1.1 running Node.js 12",
    settings: [
        {
            namespace: "aws:elasticbeanstalk:application:environment",
            name: "MQ_BROKER_ENDPOINT",
            value: mqBroker.brokerId.apply(id => `https://${id}.mq.us-west-2.amazonaws.com`), // Example resource ID resolution during deployment
        },
        {
            namespace: "aws:elasticbeanstalk:application:environment",
            name: "MQ_USERNAME",
            value: "mq_user",
        },
        {
            namespace: "aws:elasticbeanstalk:application:environment",
            name: "MQ_PASSWORD",
            value: "mq_password",
        },
    ],
});

// Export the URLs and IDs of the created resources
export const mqBrokerId = mqBroker.id;
export const mqBrokerEndpoint = mqBroker.brokerId.apply(id => `https://${id}.mq.us-west-2.amazonaws.com`);
export const elasticBeanstalkAppName = app.name;
export const elasticBeanstalkEnvName = env.name;
```

This code snippet does the following:

- Initializes a new Amazon MQ Broker with the specified name, engine type, version, and host instance type. The `user` block includes credentials for the broker, and `publiclyAccessible` is set to `true` to allow connections from the internet.
  - Note: In a production scenario, it's important to secure your MQ broker. Using Pulumi secrets to manage sensitive information like the user credential is highly recommended.

- Sets up an AWS Elastic Beanstalk application with a given name and description.

- Sets up an environment for the application on Elastic Beanstalk and associates it with the previously created application. It uses a Node.js platform as an example.
  - The `settings` are crucial here since we're passing the endpoint and credentials of the MQ broker to the Elastic Beanstalk environment. These settings become environment variables accessible by your application.

- Exports the broker ID and endpoint as well as the Elastic Beanstalk application and environment names so they can be easily referenced or used outside of Pulumi, such as in a CI/CD pipeline or for further automation.

Keep in mind, the values provided here are placeholders, especially passwords and other sensitive data. Replace these with secure, randomly generated credentials, and make sure your actual credentials are kept secret.

For a real-world scenario, you would likely use Pulumi's `Config` to manage such secrets securely. Here is a brief example of how you could do that:

```typescript
import * as pulumi from '@pulumi/pulumi';

const config = new pulumi.Config();
const mqPassword = config.requireSecret("mqPassword");
```

You would then replace `"mq_password"` with `mqPassword` in the broker definition.

After deploying this program with `pulumi up`, your AWS environment will be set up to utilize Amazon MQ with an Elastic Beanstalk-deployed application. Remember that making the MQ Broker publicly accessible is just for demonstration; you should restrict access to it in a real-world scenario.
