  title: Oracle Cloud Deploy And Invoke Function
  summary: Create a Functions application, create a function in it, then invoke the function.
  description: >-
    Deploys a serverless function on Oracle Functions and exercises it. The
    workflow creates an application bound to the supplied subnet, creates a
    function from a container image inside that application, and then invokes the
    function with a payload. Every step spells out its request inline so the
    deploy-and-invoke flow can be read and executed without opening the
    underlying OpenAPI description.
