### 正确配置 `bitnami/zookeeper` 和 `bitnami/kafka` 的 Docker 容器 为了实现 ZooKeeper 和 Kafka 集群的正确配置，可以按照以下方式设置容器及其参数。 #### 1. **ZooKeeper 配置** 对于 `bitnami/zookeeper` 容器，需要定义每个节点的身份 (`ZOO_SERVER_ID`) 及其连接地址列表。以下是具体的环境变量和端口映射： - 环境变量： - `ZOO_SERVER_ID=1`: 表示第一个 ZooKeeper 节点的 ID[^1]。 - `ZOO_SERVERS=localhost:2888:3888;localhost:2889:3889;localhost:2890:3890`: 列出了所有 ZooKeeper 节点的地址和端口。 - 端口映射： - `-p 2181:2181`: 对应客户端通信端口。 - `-p 2888:2888`: 同步端口用于内部集群同步。 - `-p 3888:3888`: Leader选举端口。 ```yaml version: '3' services: zookeeper1: image: 'bitnami/zookeeper:latest' environment: - ALLOW_ANONYMOUS_LOGIN=yes - ZOO_SERVER_ID=1 - ZOO_SERVERS=zookeeper1:2888:3888;zookeeper2:2888:3888;zookeeper3:2888:3888 ports: - '2181:2181' - '2888:2888' - '3888:3888' ``` #### 2. **Kafka 配置** 针对 `bitnami/kafka` 容器，需指定 ZooKeeper 连接字符串及其他必要参数： - 环境变量： - `KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181`: 指定 ZooKeeper 集群的连接地址。 - `ALLOW_PLAINTEXT_LISTENER=yes`: 允许明文监听器（仅适用于测试环境）[^3]。 - 端口映射： - `-p 9092:9092`: 外部访问 Kafka 的默认端口。 ```yaml kafka1: image: 'bitnami/kafka:latest' depends_on: - zookeeper1 - zookeeper2 - zookeeper3 environment: - KAFKA_BROKER_ID=1 - KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181 - ALLOW_PLAINTEXT_LISTENER=yes ports: - '9092:9092' ``` #### 3. **Network Mode** 推荐为所有服务创建一个自定义网络以便于管理和服务发现： ```yaml networks: app-tier: driver: bridge ``` 并将该网络应用到所有服务中： ```yaml services: zookeeper1: networks: - app-tier kafka1: networks: - app-tier ``` #### 4. **集成 Kafka Manager** 要监控 Kafka 集群的状态，可以通过部署 `Yahoo/kafka-manager` 来完成。具体配置如下： - 环境变量： - `ZK_HOSTS=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181`: 指向 ZooKeeper 集群的地址[^4]。 ```yaml kafka-manager: image: 'yahoo/kafka-manager:latest' environment: - ZK_HOSTS=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181 ports: - '9000:9000' networks: - app-tier ``` --- ###
