How Do I Deploy an AWS Elastic Beanstalk Environment With Docker?

Introduction

Deploying a Docker application on AWS Elastic Beanstalk allows you to leverage AWS’s scalable infrastructure to run your containerized applications efficiently. This guide outlines the process of setting up an Elastic Beanstalk application and environment configured to use Docker. We will walk through defining the necessary components and configurations to deploy your Docker container successfully.

Step-by-Step Deployment Process

1. Define IAM Role:

   • Create an IAM role with a policy that allows Elastic Beanstalk to assume the necessary permissions using AWS Identity and Access Management (IAM).

2. Create Elastic Beanstalk Application:

   • Define an Elastic Beanstalk application to act as a container for your environment versions.

3. Set Up Environment:

   • Configure an Elastic Beanstalk environment to specify the Docker platform and other settings such as instance type and environment variables.

4. Configure Docker Image:

   • Specify the Docker image to be used in the environment. In this example, we use the Nginx image, but you should replace it with your Docker image.

Here is the TypeScript code to achieve this setup:

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

const beanstalkServiceAssumeRolePolicy = aws.iam.getPolicyDocumentOutput({
    statements: [{
        actions: ["sts:AssumeRole"],
        principals: [{
            type: "Service",
            identifiers: ["elasticbeanstalk.amazonaws.com"],
        }],
    }],
});
const beanstalkService = new aws.iam.Role("beanstalk_service", {
    name: "beanstalk-service-role",
    assumeRolePolicy: beanstalkServiceAssumeRolePolicy.apply(beanstalkServiceAssumeRolePolicy => beanstalkServiceAssumeRolePolicy.json),
});
const app = new aws.elasticbeanstalk.Application("app", {
    name: "my-eb-app",
    description: "Elastic Beanstalk Application",
    appversionLifecycle: {
        serviceRole: beanstalkService.arn,
        maxCount: 128,
        deleteSourceFromS3: true,
    },
});
const env = new aws.elasticbeanstalk.Environment("env", {
    name: "my-eb-env",
    application: app.name,
    solutionStackName: "64bit Amazon Linux 2 v3.3.6 running Docker",
    settings: [
        {
            namespace: "aws:elasticbeanstalk:environment:process:default",
            name: "PORT",
            value: "80",
        },
        {
            namespace: "aws:autoscaling:launchconfiguration",
            name: "InstanceType",
            value: "t2.micro",
        },
        {
            namespace: "aws:elasticbeanstalk:container:docker",
            name: "DockerImage",
            value: "nginx",
        },
    ],
});

Key Points

• IAM Roles: Ensure the IAM roles are correctly set up to allow Elastic Beanstalk to perform necessary operations.
• Docker Image: Replace the Nginx Docker image with your specific application image.
• Environment Configuration: Properly configure environment settings, such as instance type and environment variables, to suit your application needs.

Conclusion

By following these steps, you have successfully deployed an AWS Elastic Beanstalk environment configured to run Docker containers. This setup allows you to take advantage of AWS’s robust infrastructure to manage and scale your Docker applications efficiently. Make sure to tailor the configurations to fit the specific requirements of your application for optimal performance.
