1. Using aws secretsmanager with elasticbeanstalk

    TypeScript

    To integrate AWS Secrets Manager with AWS Elastic Beanstalk, you would typically follow these steps:

    1. Create a Secret: Start by creating a secret in AWS Secrets Manager to hold your sensitive information.
    2. Set up Elastic Beanstalk Environment: Then set up an AWS Elastic Beanstalk environment where your application will run.
    3. Configure Environment to Use Secret: You will configure the Elastic Beanstalk environment to use the secret you stored in Secrets Manager, often by setting environment variables or including it in your application's configuration.

    The following Pulumi program in TypeScript demonstrates how to create a secret in AWS Secrets Manager and use it with an Elastic Beanstalk application. The secret could contain database credentials, API keys, or any other sensitive data your application needs.

    Before you run this program, ensure you have the necessary AWS credentials configured for Pulumi CLI on your development machine.

    import * as aws from "@pulumi/aws"; // Create a new secret in AWS Secrets Manager const dbCredentialsSecret = new aws.secretsmanager.Secret("dbCredentials", { description: "Database credentials for my application", // Secret values can be set here or dynamically generated. // For dynamic secrets, use the 'generateSecretString' option. secretString: JSON.stringify({ username: "my-app-user", password: "my-app-password", }), }); // Create an Elastic Beanstalk application const app = new aws.elasticbeanstalk.Application("my-app", { description: "My Elastic Beanstalk Application", }); // Define the application version based on a given source, such as a code commit on S3 const appVersion = new aws.elasticbeanstalk.ApplicationVersion("my-app-version", { application: app.name, description: "Version 1.0", sourceBundle: { // For example, this could be a reference to a ZIP file containing your application's code. s3Bucket: "my-application-bucket", s3Key: "versions/1.0.zip", }, }); // Create an Elastic Beanstalk environment const env = new aws.elasticbeanstalk.Environment("my-app-env", { application: app.name, solutionStackName: "64bit Amazon Linux 2 v5.4.4 running Node.js 14", settings: [ // Retrieve the secret from AWS Secrets Manager and set it as an env variable { namespace: "aws:elasticbeanstalk:application:environment", name: "DB_CREDENTIALS", value: dbCredentialsSecret.arn.apply(arn => `{{resolve:secretsmanager:${arn}}}`), }, // Additional environment configurations can be set here ], // Set the version to deploy version: appVersion, }); // Export the URL of the environment export const elasticBeanstalkEnvironmentURL = env.endpointUrl; // Export the Secret ARN export const secretArn = dbCredentialsSecret.arn;

    Explanation:

    • Secret Creation: aws.secretsmanager.Secret creates a secret in AWS Secrets Manager. We store a JSON string containing the username and password. In a production setting, you'd want to generate the password dynamically and not store it in plaintext within source control.

    • AWS Secrets Manager

    • Elastic Beanstalk Application: The aws.elasticbeanstalk.Application resource creates a new application in AWS Elastic Beanstalk.

    • AWS Elastic Beanstalk Application

    • Application Version: aws.elasticbeanstalk.ApplicationVersion defines a version for the Elastic Beanstalk Application. It usually represents a snapshot of the application code and configuration.

    • AWS Elastic Beanstalk ApplicationVersion

    • Environment Configuration: aws.elasticbeanstalk.Environment defines an environment for the application. Here, we set an environment variable DB_CREDENTIALS which references the secret we created. The actual value fetched from the Secrets Manager will be fed into the environment variable at runtime.

    • AWS Elastic Beanstalk Environment

    This is a starting point for integrating AWS Secrets Manager with AWS Elastic Beanstalk. Depending on your application's specific requirements, you might need additional configurations, such as linking to an RDS database or setting up environment variables for other services.
