Features Permalink to "Features"

Kafka is a popular publish-subscribe messaging system. JHipster has an optional support for Kafka, that will:

  • Configure Kafka clients with JHipster.
  • Add the necessary configuration in the application-*.yml
  • Generate a Docker Compose configuration file, so Kafka is usable by typing docker-compose -f src/main/docker/kafka.yml up -d.

Prerequisite Permalink to "Prerequisite"

Generate a new application and make sure to select Asynchronous messages using Apache Kafka when prompted for technologies you would like to use. A Docker Compose configuration file is generated and you can start Kafka with the command:

docker-compose -f src/main/docker/kafka.yml up -d
