kafka容器增加健康检查

kafka:

image: bitnami/kafka:2.6.0

container_name: kafka

networks:

• zhongn-net

ports:

• "9092:9092"

environment:

• KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper:2181

• ALLOW_PLAINTEXT_LISTENER=yes

• KAFKA_BROKER_ID=1

• KAFKA_CFG_LISTENERS=PLAINTEXT://:9092

• KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://10.235.32.37:9092

volumes:

• /opt/iot_security/middle/kafka:/bitnami/kafka

restart: always

✅✅✅ 最终安全健康检查（无依赖、不挑网卡、不用root）

healthcheck:

test: "CMD", "kafka-topics.sh", "--list", "--bootstrap-server", "localhost:9092"

interval: 20s

timeout: 10s

retries: 2

start_period: 40s

应为kafka容器在某种情况下会出现网络异常，导致连接不上，增加健康检查，如果异常就重启。
