Get Docker (Desktop).

Start a stack with Zookeeper, Kafka and a topic initializer.

> docker compose up

Wait for a message saying "Ready to go!"

Start application with localhost profile, e.g.

> mvn -D'spring-boot.run.arguments'='--spring.config.name=localhost' spring-boot:run

or preferably using a Spring Boot run configuration in IntelliJ with program arguments --spring.config.name=localhost.

• Reduce logging in localhost Kafka stack.
