  title: Amazon Elastic Beanstalk Add Environment To Application
  summary: Confirm an existing application, launch an additional environment for it, and poll until Ready.
  description: >-
    A blue/green-style flow that stands up an additional environment for an
    application that already exists. It first verifies the application is present
    with DescribeApplications, then launches a new environment for it on the
    supplied solution stack and application version, and finally polls the
    environment description until its status reaches Ready. Every step spells out
    its AWS query-protocol request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
