Kruize Optimizer

Tag It | Forget It | Optimize It

A lightweight Quarkus‑based microservice that automates configuration, experiment creation, profile validation, and health orchestration for Kruize Autotune, simplifying the experience for SREs and Platform Engineers.

Prerequisites

• Java 25 - Required to build the Docker image and run the application

Deployment

Deploy to Kind (local development)

kubectl apply -k deployment/overlays/kind

This deploys to the monitoring namespace.

Deploy to OpenShift

kubectl apply -k deployment/overlays/openshift

This deploys to the openshift-tuning namespace.

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 quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

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

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

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Dnative

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

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

You can then execute your native executable with: ./target/kruize-optimizer-1.0.0-SNAPSHOT-runner

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