backbase-operator project

This project uses Quarkus, the Supersonic Subatomic Java Framework.

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 quarkus:dev

Packaging and running the application

The application can be packaged using ./mvnw package. It produces the bb-operator-1.0-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.

The application is now runnable using java -jar target/bb-operator-1.0-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/bb-operator-1.0-SNAPSHOT-runner

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

Testing

TL;DR

kubectl apply -f k8s_files/

Explanation

By default, Pods in Kubernetes do not have the permission to list other pods. Therefore, we need to create a cluster role, a service account, and a cluster role binding.

kubectl apply -f k8s_files/operator.clusterrole.yaml
kubectl apply -f k8s_files/operator.serviceaccount.yaml
kubectl apply -f k8s_files/operator.clusterrolebinding.yaml

Now you can run the kubectl apply -f k8s_files/operator.crd.yaml command to register the CRD in the cluster.

Run the kubectl apply -f k8s_files/operator.deployment.yaml command to register the operator.

Running the example

Apply the custom resource by running: kubectl apply -f cx-statics.yaml and check the output of kubectl get pods command.
