  title: Amazon Elastic Beanstalk Deploy Version To Environment
  summary: Deploy an application version to a running environment and poll until the update completes.
  description: >-
    The standard Elastic Beanstalk deployment flow. It confirms the target
    environment is currently Ready, deploys a new application version to it via
    UpdateEnvironment, and then polls the environment description until the
    update finishes and the environment returns to Ready (branching out on a
    terminal Terminated status). Every step spells out its AWS query-protocol
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
