Function

Function is a resource that is directly defined and controlled by the user. It is a description of the user’s application, i.e. what raw materials (source code) are used to make the product (application image) and how it will ultimately work (workload, runtime).

In OpenFunction, the Function resource controls the coordination of Builder and Serving in an orderly manner according to the configuration, thus implementing the lifecycle management of user functions.
