Testing locally can be done as follows:

1. Run the following command in terminal

docker-compose up -d

This will enable us to run the Postgres, Zookeeper, Kafka and Kafka Manager containers on the ports we specify in the docker-compose.yaml file.

2. Run the following command to compile the maven project

mvn clean install -DskipTests

3. Run ProducerMicroservicesApplication and ConsumerMicroservicesApplication

4. Make requests to these endpoints

http://localhost:8081/producerDomain/save
