quarkus-funqy-events project

This project uses Quarkus and the Funqy extension to showcase a simple function chain. You will need stern, kubectl, kn, oc binaries installed on your local machine.

If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-funqy-events-1.0.0-SNAPSHOT-runner.jar file in the /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application is now runnable using java -jar target/quarkus-funqy-events-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/quarkus-funqy-events-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.html.

Things you need to do before running the events on Openshift/kubernetes

Creating the default broker

kn broker create default --namespace knativetutorial

kn broker -n knative tutorial list

Dont forget to change the container image settings in application.properties and the src/main/k8s/funqy-service.yaml

Deploying the eventing app.

kubectl apply -n knativetutorial -f src/main/k8s/funqy-service.yaml

# And the function chain

kubectl apply -n knativetutorial -f src/main/k8s/defaultChain-trigger.yaml
kubectl apply -n knativetutorial -f src/main/k8s/configChain-trigger.yaml
kubectl apply -n knativetutorial -f src/main/k8s/annoatedChain-trigger.yaml
kubectl apply -n knativetutorial -f src/main/k8s/lastChainLink-trigger.yaml

running the curler to throw some POST requests to the broker.

kubectl apply -n knativetutorial -f src/main/k8s/curler.yaml
kubectl -n knativetutorial exec -it curler -- /bin/bash

running stern to watch your pods.

stern funq -c user-container

running against the broker directly
