运行docker-compose.yaml

docker compose -f ./docker-compose.yaml up -d

测试kafka

• 进入容器

docker exec -it kafka bash 

• 创建topic

/opt/kafka/bin/kafka-topics.sh --bootstrap-server kafka:9092 --create --topic topic-test

• 打开生产者，在终端发送消息

/opt/kafka/bin/kafka-console-producer.sh --bootstrap-server kafka:9092 --topic topic-test

• 另外打开一个终端，进入容器

docker exec -it kafka bash 

• 打开消费者，接收消息

/opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic test-topic --from-beginning
