  6. Choose the Application Code option.
  7. Select the Upload your code option.
  8. Click on the Choose file button and select the zip file containing your application code.
  9. Click on the Create application button.

Step 2: Create an Environment

An environment is a collection of AWS resources that are linked to an application and are used to run the application. To create an environment for your application, follow the steps below:

  1. In the Elastic Beanstalk console, select the application you previously created.
  2. Click on the Create new environment button.
  3. Choose the Web server environment option.
  4. Enter a name for your environment.
  5. Choose a domain name for your environment.
  6. Select a platform version based on the platform that your application runs on.
  7. Choose one of the predefined configurations. For example, Load Balanced, Auto Scaling, or Single Instance.
  8. Optionally, configure the environment settings. For example, the instance type, SSH access, or the number of instances.
  9. Click on the Create environment button.

Step 3: Upload your Application Code

To upload your application code to the environment, follow the steps below:

  1. In the Elastic Beanstalk console, select the environment you previously created.
  2. Click on the Upload and deploy button.
  3. Choose the Local file option.
  4. Choose the zip file containing your application code.
  5. Optionally, enter a version label for your application.
  6. Click on the Upload button.

Step 4: Test your Environment

To test your environment, follow the steps below:

  1. In the Elastic Beanstalk console, select the environment you previously created.
  2. Click on the URL of your environment.
  3. Verify that your application is running correctly.

Step 5: Update your Application

To update your application, follow the steps below:

  1. Make the necessary changes to your application code.
  2. Commit your changes using Git.
  3. Create a new version of your application by running the following command:
$ eb create --version label

Replace label with a version label for your application.

  1. Upload the new version of your application to the environment by running the following command:
$ eb deploy
  1. Test your application to ensure that it is running correctly.

Step 6: Monitor your Environment

Elastic Beanstalk provides a variety of monitoring options to help you keep track of your environment’s health and performance. To monitor your environment, follow the steps below:

  3. Review the charts and metrics to gain insight into the health and performance of your environment.

Step 7: Clean up

To clean up your environment and application, follow the steps below:

  1. In the Elastic Beanstalk console, select the environment you previously created.
  2. Click on the Actions button and select Terminate environment.
  3. Confirm that you want to terminate the environment.
  4. In the Elastic Beanstalk console, select the application you previously created.
  5. Click on the Actions button and select Delete application.
  6. Confirm that you want to delete the application.

Conclusion

In this tutorial, we learned how to deploy an application on Elastic Beanstalk. We started by creating an application, creating an environment, uploading our application code, testing our environment, updating our application, monitoring our environment, and finally cleaning up our environment and application. Elastic Beanstalk simplifies the deployment of our applications, making it easier to manage and scale our applications in the cloud.
