You can use the Elastic Beanstalk Application task to create, update or delete an AWS Elastic Beanstalk application (see AWS Elastic Beanstalk Components for details on applications, versions and environments).
Configuration
While useful for full scale automation and test scenarios, it is quite common to create target applications e.g. via the AWS Management Console upfront and only manage Application Versions and Environments from your build and deployment projects.
- on a similar note, the Update action is included for complete API coverage, but use cases for updating the Application Description only are supposedly rare
To ease common scenarios, the Create action allows to Update [the] application, if it already exists, similarly the Update action allows to Create [the] application, if it does not already exist.
