# Introduction
This example shows GraaalVM native spring-cloud-function application. The application itself is very simple and contains two functions - `uppercase` & `lowercase`.
Unless specific value is specified as `handler`, the application will fall back on `RoutingFunction` where you can pass the routing instruction
via `spring.cloud.function.definition` Message header. If using API Gateway you can pass such header as HTTP header.
# To run
## If you are on OSX Apple M1 Pro (arch64)

$ docker run -dit al2-graalvm19:native-uppercase

Now navigate to the image terminal. Your working directory is alredy set for the root of the project. You can verify it by executing `ls`.
