Composer (in the misc folder)

docker-compose -f docker-composer.yml up -d

Topics creation

docker exec -it [container_id] kafka-topics.sh --create --bootstrap-server localhost:9092 --topic input-harga

docker exec -it [container_id] kafka-topics.sh --create --bootstrap-server localhost:9092 --topic topup

Kafka adjustment:

Accessing outside the docker host

  KAFKA_ADVERTISED_HOST_NAME: localhost
  KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092

Accessing inside the cluster (where kafka1 is that hostname: kafka1)

  KAFKA_ADVERTISED_HOST_NAME: kafka1
  KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka1:9092

Exposed ports:

• Kafka

  ports:

    - "9092:9092"
    - "29092:29092"
    - "9999:9999"
  

• Postgres

  ports:

    - "5433:5432"
  

If it is for some unknown reasons things fail in your system, an alternative way is to creating a custome internal network (bridge mode) then attach all containers to that network.

docker network create -d bridge [network_name]

docker run -itd --network=network_name [container_id]
