**To create a new application version**

The following command creates a new version, "v1" of an application named "MyApp"::

  aws elasticbeanstalk create-application-version --application-name MyApp --version-label v1 --description MyAppv1 --source-bundle S3Bucket="my-bucket",S3Key="sample.war" --auto-create-application

The application will be created automatically if it does not already exist, due to the auto-create-application option. The source bundle is a .war file stored in an s3 bucket named "my-bucket" that contains the Apache Tomcat sample application.

Output::

  {
    "ApplicationVersion": {
        "ApplicationName": "MyApp",
        "VersionLabel": "v1",
        "Description": "MyAppv1",
        "DateCreated": "2015-02-03T23:01:25.412Z",
        "DateUpdated": "2015-02-03T23:01:25.412Z",
        "SourceBundle": {
            "S3Bucket": "my-bucket",
            "S3Key": "sample.war"
        }
    }
  }
