MN Kafka integration

Prerequisites

• Docker: https://docs.docker.com/get-docker/

Running Kafka as a Docker container

• Run docker-compose up in order to start Zookeeper and Kafka within docker container.

Native image properties setup

Args= -H:IncludeResources=logback.xml|application.yml
-H:Name=mn-pricing
-H:Class=com.danielprinz.udemy.Application
--report-unsupported-elements-at-runtime
--initialize-at-run-time=org.apache.kafka.common.security.authenticator.SaslClientAuthenticator

Some classes have to be initialized during an image runtime. That can be achieved by using the following option: --initialize-at-run-time=<class-name>

Building native image with gradle

• When building nativeImage with gradle we have to be careful with how we are setting up dependencies e.g. if some test dependencies are problematic we have to replace the deprecated testCompile with testImplementation.
• Once everything configured, we can create a native image in the following way: $ ./gradlew nativeImage (or gradle nativeImage)

Running native-image

If native-image is successfully created, it can be launched by simply running the following command: .\build\native-image\application.exe
