Jib Quarkus Extension

Experimental: may fail to work on complex projects. Does not cover "native" Quarkus packaging type.

Enables containerizing a Quarkus app built with Quarkus Gradle Plugin.

The Quarkus app framework has two different package types:

• legacy-jar: original Quarkus "runner" JAR
• fast-jar: default Quarkus package type since 1.12

You can use either package type with Jib Quarkus extension by configuring the pluginExtensions.pluginExtension.properties. Default value is the legacy-jar, but can be easily changed to fast-jar.

Examples

Check out the general instructions for applying a Jib plugin extension.

Note that container.mainClass should be set to some placeholder value to suppress Jib warning about missing main class. Package type has two valid values: fast-jar and legacy-jar.

// should be at the top of build.gradle
buildscript {
  dependencies {
    classpath('com.google.cloud.tools:jib-quarkus-extension-gradle:0.1.2')
  }
}

...

jib {
  ...
  container {
    mainClass = 'bogus'  // to suppress Jib warning about missing main class
    ...
    jvmFlags = ['-Dquarkus.http.host=0.0.0.0', '-Djava.util.logging.manager=org.jboss.logmanager.LogManager']
    ports = ['8080']
    user = '1001'
  }
  pluginExtensions {
    pluginExtension {
      implementation = 'com.google.cloud.tools.jib.gradle.extension.quarkus.JibQuarkusExtension'
      properties = [packageType: 'fast-jar'] // to use Quarkus fast-jar package type
    }
  }
}

Standard Jib Configurations

By the way Quarkus needs to run (via java -jar quarkus-runner.jar or java -jar quarkus-app/quarkus-run.jar), some standard Jib configurations will have no effect:

• container.mainClass
• container.entrypoint (Note container.args continues to work.)
• container.extraClasspath
• containerizingMode
