Before Running Services

Make sure there is a Kafka server running

cd kafka
docker-compose up
  • Check the Kafka messages:
cd infra
docker-compose exec -it kafka /bin/bash
cd /bin
./kafka-console-consumer --bootstrap-server localhost:9092 --topic

  • order
  • support
  • dashboard

cd gateway
mvn spring-boot:run
