12. Check for the instance-id value that matches your Elastic Beanstalk environment instance-id value and view the load balancers.

You have successfully changed an environment configuration on AWS Elastic Beanstalk.

EXERCISE 6.4

Update an Application Version on AWS Elastic Beanstalk

In this exercise, you will update an application version on AWS Elastic Beanstalk from the AWS Management Console.

1. Sign in to your AWS account.
2. Upload a second version your application that matches the configuration for your current running environment.

• If you are using a sample solution application, you can find other versions at the following address:
• https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/GettingStarted.html#GettingStarted.Walkthrough.DeployApp

3. On the AWS EB applications page, select getting-started-app.
4. Select GettingStartedApp-env.
5. In Overview, choose Upload and Deploy.
6. Select Choose File and upload the next version of your source bundle that you created or downloaded.

• The console is automatically populated with the version label based on the name of the archive that you upload. For later deployments, if you use a source bundle with the same name, you must type a unique version label.

7. Choose Deploy. Elastic Beanstalk deploys your application to your Amazon EC2 instances.

• You can view the status of the deployment on the environment’s dashboard. The Environment Health status turns gray while the application version is being updated. When deployment is complete, Elastic Beanstalk executes an application health check. The status reverts to green when the application responds to the health check. The environment dashboard shows the new running version as the new version label. Your new application version is added to the table of application versions.

8. To view the table, select Application Versions.

• You have updated an application version on AWS Elastic Beanstalk.
