使用 Docker Compose 进行Kafak集群部署代码教程_kafka启动docker compose文件

Docker Compose

介绍

Docker Compose是用于定义和运行多容器 Docker 应用程序的工具。通过 Compose，可以使用 YML 文件来配置应用程序需要的所有服务。然后使用一个命令，就可以从 YML 文件配置中创建并启动所有服务。

安装Docker Compose

从Github上下载

sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /opt/docker-compose
1

若网络出现问题，输入下列命令查看下载地址，可在Windows系统中加入科技后下载

echo "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)
1

为Docker Compose的二进制文件赋予执行权限：

sudo chmod +x /opt/docker-compose
1

到配置文件中配置环境变量

vim /etc/profile
1

输入路径

export PATH="/opt:$PATH"
1

刷新环境变量

source /etc/profile
1

验证是否安装

docker-compose --version
1

启动docker compose

开启

docker-compose up -d
1

关闭

docker-compose down
1

使用脚本安装Kafka集群

使用docker-compose.yml文件，创建一个包含了一个 ZooKeeper 节点和一个 Kafka 节点的集群

version: '3'
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:7.1.0
    volumes:
      - /tmp/zookeeper:/var/lib/zookeeper/data
      - /tmp/zookeeper/logs:/var/lib/zookeeper/logs
    ports:
      - "2181:2181"
  kafka1:
    image: confluentinc/cp-kafka:7.1.0
    volumes:
      - /tmp/kafka:/var/lib/kafka1/data
    depends_on:
      - zookeeper
    ports:
      - "9092:9092"
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092,PLAINTEXT_HOST://localhost:9092
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
  kafka2:
    image: confluentinc/cp-kafka:7.1.0
    volumes:
      - /tmp/kafka:/var/lib/kafka2/data
    depends_on:
      - zookeeper
    ports:
      - "9093:9092"
    environment:
      KAFKA_BROKER_ID: 2
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka2:9092
  kafka3:
    image: confluentinc/cp-kafka:7.1.0
    volumes:
      - /tmp/kafka:/var/lib/kafka3/data
    depends_on:
      - zookeeper
    ports:
      - "9094:9092"
    environment:
      KAFKA_BROKER_ID: 3
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka3:9092
