Compiling your Quarkus applications to native executables

Procedure

1. Open the Getting Started project pom.xml file and verify that it includes the native profile:

   <profiles>
       <profile>
           <id>native</id>
           <properties>
               <quarkus.package.type>native</quarkus.package.type>
           </properties>
       </profile>
   </profiles>

   Note

   Using Quarkus native profile allows you to run both the native executable and the native image tests.

2. Build a native executable using one of the following methods:

   1. Build a native executable with Docker:

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

   2. Build a native executable with Podman:

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

      These commands create the getting-started-*-runner binary in the target directory.

      Important

      Compiling a Quarkus application to a native executable consumes a lot of memory during analysis and optimization. You can limit the amount of memory used during native compilation by setting the quarkus.native.native-image-xmx configuration property. Setting low memory limits might increase the build time.

3. Run the native executable:

   ./target/getting-started-*-runner

   When you build the native executable the prod profile is enabled and the Quarkus native tests run using the prod profile. You can change this using the quarkus.test.native-image-profile property.

Procedure

1. Open the pom.xml file and verify that the native profile contains the following elements:

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-failsafe-plugin</artifactId>
       <version>${surefire-plugin.version}</version>
       <executions>
           <execution>
               <goals>
                   <goal>integration-test</goal>
                   <goal>verify</goal>
               </goals>
               <configuration>
                   <systemPropertyVariables>
                       <native.image.path>${project.build.directory}/${project.build.finalName}-runner</native.image.path>
                       <java.util.logging.manager>org.jboss.logmanager.LogManager</java.util.logging.manager>
                       <maven.home>${maven.home}</maven.home>
                   </systemPropertyVariables>
               </configuration>
           </execution>
       </executions>
   </plugin>

   The failsafe-maven-plugin runs integration test and indicates the location of the produced native executable.

2. Open the src/test/java/org/acme/quickstart/NativeGreetingResourceIT.java file and verify that it includes the following content:

   package org.acme.quickstart;
   
   
   import io.quarkus.test.junit.NativeImageTest;
   
   @NativeImageTest 1
   public class NativeGreetingResourceIT extends GreetingResourceTest { 2
   
       // Run the same tests
   
   }

   1

   Use another test runner that starts the application from the native file before the tests. The executable is retrieved using the native.image.path system property configured in the Failsafe Maven Plugin.

   2

   This example extends the GreetingResourceTest, but you can also create a new test.

3. Run the test:

   ./mvnw verify -Pnative

   The following example shows the output of this command:

   ./mvnw verify -Pnative

   Note

   Quarkus waits for 60 seconds for the native image to start before automatically failing the native tests. You can change this duration using the quarkus.test.native-image-wait-time system property.

   You can extend the wait time using the following command where <duration> is the wait time in seconds:

   ./mvnw verify -Pnative -Dquarkus.test.native-image-wait-time=<duration>
