Deploying a Spring Boot application to Amazon Web Services (AWS) can be a powerful way to leverage the cloud's scalability, reliability, and global reach. In this section, we will cover the steps required to deploy a Spring Boot application to AWS, focusing on Elastic Beanstalk, a service that makes it easy to deploy and manage applications in the AWS cloud.

Before we begin, ensure you have the following:

• An AWS account.
• AWS CLI installed and configured on your local machine.
• A Spring Boot application ready for deployment.

Step 1: Install the AWS Elastic Beanstalk CLI

First, install the Elastic Beanstalk Command Line Interface (EB CLI) to manage your application from the command line.

Step 2: Initialize Elastic Beanstalk

Navigate to your Spring Boot project directory and initialize Elastic Beanstalk.

You will be prompted to select a region and provide your AWS credentials. Follow the prompts to configure your application.

Step 1: Create an Environment

Create an environment for your application. This environment will host your Spring Boot application.

This command will create an environment named spring-boot-env. You can choose a different name if you prefer.

Step 1: Update application.properties

Ensure your application.properties file is configured correctly for production. For example, you might want to set the server port and database configurations.

Step 2: Create a Procfile

Create a Procfile in the root of your project directory. This file tells Elastic Beanstalk how to run your application.

Replace your-application.jar with the name of your Spring Boot JAR file.

Step 1: Build Your Application

Build your Spring Boot application using Maven or Gradle.

For Maven:

For Gradle:

Step 2: Deploy to Elastic Beanstalk

Deploy your application to the Elastic Beanstalk environment.

This command will upload your application and deploy it to the environment you created.

Once the deployment is complete, you can access your application using the URL provided by Elastic Beanstalk. You can find this URL in the AWS Management Console under the Elastic Beanstalk section.

1. Clone a Sample Spring Boot Application:

   git clone https://github.com/spring-guides/gs-spring-boot.git
   cd gs-spring-boot/complete
   

2. Initialize Elastic Beanstalk:

   eb init
   

3. Create an Environment:

   eb create sample-spring-boot-env
   

4. Build the Application:

   mvn clean package
   

5. Create a Procfile:

   web: java -jar target/gs-spring-boot-0.1.0.jar
   

6. Deploy the Application:

   eb deploy
   

7. Access the Application:

   • Navigate to the URL provided by Elastic Beanstalk.

Follow the steps outlined in the exercise to deploy the sample Spring Boot application. Ensure each command executes successfully and verify the application is running by accessing the provided URL.

In this section, we covered the steps to deploy a Spring Boot application to AWS using Elastic Beanstalk. We discussed setting up Elastic Beanstalk, configuring your Spring Boot application, and deploying it. By following these steps, you can leverage AWS's powerful infrastructure to host your Spring Boot applications efficiently. In the next section, we will explore deploying Spring Boot applications to Kubernetes.
