Example Java Funktion

This example shows how easy it is to develop a funktion in Java.

The source code consists of:

• funktion.yml to define the trigger URL (in this case HTTP)
• main() function in Java to process incoming events

You can then run your funktion locally via:

mvn

You can then invoke it via your web browser at http://localhost:8080/?name=Funktion

Trying your funktion on Kubernetes or OpenShift

Assuming your current shell is connected to Kubernetes or OpenShift so that you can type a command like

kubectl get pods

or for OpenShift

oc get pods

Then the following command will package your funktion and run it on Kubernetes:

mvn install fabric8:deploy
