This project builds on Payara Micro as the JEE container, and constitues a very simple EJB based version of the consumer which has one singleton to hold the MQTT client and one for the ElasticSearch client, and lastly one startup singleton which marries the two.
Use the gradle wrapper and the docker build script:
./gradlew clean build && ./docker_build
Fire up the scenario with docker compose:
docker-compose up -d ; docker-compose logs -f
and end it with:
docker-compose stop ; docker-compose rm -f
