Quarkus Cookbook

Chapter 6. Packaging Quarkus Applications

In this chapter, you will learn about packaging a Quarkus service into a JVM or a native format so that it can be distributed and deployed. Today, when containers are becoming the standard way to distribute applications, you need to know how to containerize them.

We’ll cover the following topics:

• How to package a Quarkus application for running in the JVM

• How to package a Quarkus application in a native executable

• How to containerize a Quarkus application

6.1 Running in Command Mode

Problem

You want to create a CLI application.

Solution

With Quarkus, you can also write applications that run and then optionally exit.

To enable command mode in Quarkus, you need to create a class that implements the io.quarkus.runtime.QuarkusApplication interface:

package org.acme.quickstart;

import io.quarkus.runtime.Quarkus;
import io.quarkus.runtime.QuarkusApplication;

public class GreetingMain implements QuarkusApplication { 

    @Override
    public int run(String... args) throws Exception { 
        System.out.println("Hello World");
        Quarkus.waitForExit(); 
        return 0;
    }

}
