Guide for docker-compose.yaml:

1. SSH to VM and prepare env

Create required directories:

mkdir kafka && cd kafka
mkdir zk1 zk2 zk3 kf1 kf2 kf3

Copy docker-compose

vi docker-compose.yaml

Start docker compose

docker-compose up -d

Get docker network private IPs of container instances

docker ps -a
docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container_name>

2. Connect to kafka containers

docker exec -it <container_name> /bin/bash

Broker 1 container:

kafka-topics --create --bootstrap-server localhost:9092 --replication-factor 3 --partitions 3 --topic reviews
kafka-topics --list --bootstrap-server localhost:9092
kafka-topics --bootstrap-server localhost:9092 --describe --topic reviews
kafka-console-producer --topic reviews --bootstrap-server localhost:9092

Broker 2 container:

kafka-console-consumer --topic reviews --from-beginning --bootstrap-server localhost:9092
