Quarkus is the bright new star in the cloud-native App Dev universe! Quarkus is Red Hat’s upstream stack for Kubernetes native Java. Its characteristics are simple:
- Quarkus is small!
- Quarkus is fast!
- Quarkus is familiar!
… and Quarkus makes Java relevant again in the cloud-native world where everyone talks about lightweight architectures, event-driven paradigms, container platforms and languages other than Java. Why? Languages like Go and Node.js are supposed to fit better the requirements that come along with it.
Let’s see if this still holds true …
Getting Started – The Quarkus Maven Plugin
Let’s get started and let’s create an example from scratch. We first start with … hmmmm … what’s exactly our first step? Copy a skeleton from some older project? Search the web for some examples? Tailor the copied code until it fits our needs? Crossing fingers to hit a current Maven POM with the latest dependencies? But is it exactly what we need?
Quarkus was built with Developer Joy in mind! We simply do what a developer is used to do: use Maven! Quarkus provides you a Maven plugin to make your life easier:

[INFO] Quarkus - Maven Plugin 1.9.0.Final
Build parent to bring in required dependencies
This plugin has 18 goals:
quarkus:add-extension
Allow adding an extension to an existing pom.xml file. Because you can add one
or several extension in one go, there are 2 mojos: add-extensions and
add-extension. Both supports the extension and extensions parameters.
quarkus:add-extensions
Allow adding extensions to an existing pom.xml file. Because you can add one
or several extension in one go, there are 2 mojos: add-extensions and
add-extension. Both supports the extension and extensions parameters.
quarkus:analyze-call-tree
Analyze call tree of a method or a class based on an existing report produced
by Substrate when using -H:+PrintAnalysisCallTree, and does a more meaningful
analysis of what is causing a type to be retained.
quarkus:build
Build the application.
You can build a native application runner with native-image
quarkus:create
This goal helps in setting up Quarkus Maven project with quarkus-maven-plugin,
with sensible defaults
quarkus:create-extension
Creates a triple of stub Maven modules (Parent, Runtime and Deployment) to
implement a new Quarkus Extension.
Adding into an established source tree
If this Mojo is executed in a directory that contains a pom.xml file with
packaging pom the newly created Parent module is added as a child module to
the existing pom.xml file.
Creating a source tree from scratch
Executing this Mojo in an empty directory is not supported yet.
quarkus:dev
The dev mojo, that runs a quarkus app in a forked process. A background
compilation process is launched and any changes are automatically reflected in
your running application.
You can use this dev mode in a remote container environment with remote-dev.
quarkus:generate-code
quarkus:generate-code-tests
quarkus:generate-config
Generates an example application-config.properties, with all properties
commented out If this is already present then it will be appended too,
although only properties that were not already present
quarkus:help
Display help information on quarkus-maven-plugin.
Call mvn quarkus:help -Ddetail=true -Dgoal=<goal-name> to display parameter
details.
quarkus:list-extensions
List the available extensions. You can add one or several extensions in one
go, with the 2 following mojos: add-extensions and add-extension. You can list
all extension or just installable. Choose between 3 output formats: name,
concise and full.
quarkus:native-image
Deprecated. No reason given
quarkus:prepare
quarkus:prepare-tests
quarkus:remote-dev
The dev mojo, that connects to a remote host.
quarkus:remove-extension
Allow removing an extension from an existing pom.xml file. Because you can
remove one or several extension in one go, there are 2 mojos:
remove-extensions and remove-extension. Both supports the extension and
extensions parameters.
quarkus:remove-extensions
Allow removing extensions to an existing pom.xml file. Because you can remove

Ready For Hacking – The Live Coding Mode
One of the adorable features among a few others is the live coding mode. Literally speaking this is a shortcut from the unpopular code-compile-stop-deploy-restart-test cycle to just code-and-test!
This is by far not limited to just strings. It also includes structural changes to a class, changes to the Maven POM or adding properties to the one and only single properties file for configuration.
We all know and remember the times when we devs complained about slow hardware, CPU upgrades badly needed, regular SSDs too slow, NVMe is the new standard! Or my all time favourite: “There’s not enough time for writing automated tests! Schedule’s too tight, dev lifecycle takes too much time!”, etc. Sounds familiar?
Sorry folks! No excuses anymore!
Open to the world – OpenShift Deployment Made Easy
Once we’re done with local development we are gonna deploy it to a Kubernetes driven platform.
“But, wait!??!! Kubernetes? I’ve heard there’s a lot of YAML to hack before being able to deploy to such environments.” And yes, you’re right, but Quarkus is here to help you out:
We need to add a dependency to our project which will take care of all the Kubernetes YAML stuff:

You can add applications to this project with the 'new-app' command. For example, try:
oc new-app ruby~https://github.com/sclorg/ruby-ex.git
to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:
kubectl create deployment hello-node --image=gcr.io/hello-minikube-zero-install/hello-nodeCode language: JavaScript (javascript)After we have created our namespace on OpenShift we are now ready to start the deployment. This is as easy as using this ordinary Maven command:
