Docker安装RocketMQ

安装 Redis

安装dashboard

• 下载clone dashboard(源码)
• 下载dashboard(现成的jar)
• 若下载现成的jar就不用maven打包，只需要将jar放在Dockerfile目录下的target目录下，或者改Dockerfile都行
• 若是用的源码，需要用maven打包，然后将下面的Dockerfile放在项目根目录下

  Dockerfile

  # 使用官方Java运行时环境作为基础镜像
  FROM java:8
    
  # 设置时区（可选，根据你的需要）  
  ENV TZ=Asia/Shanghai  
  RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
  
  # 假设你的jar文件和Dockerfile在同一目录下  
  COPY target/rocketmq-dashboard-1.0.1-SNAPSHOT.jar /app-nq/rocketmq-dashboard.jar
    
  # 设置工作目录为/  
  WORKDIR /app-nq
    
  # 定义容器启动时执行的命令  
  # 使用exec形式运行jar包，这样可以让容器成为该进程的主进程  
  # 这样可以确保Docker可以正确发送信号和回收进程
  CMD ["java", "-jar", "/app-nq/rocketmq-dashboard.jar"]
    
  # 暴露应用的端口，假设你的Spring Boot应用运行在8080端口  
  EXPOSE 8082

• 执行docker build -t rocketmq-dashboard:1.0.1 .命令构建镜像

docker-compose编排容器

• 下载docker-compose

• 创建文件E:/Docker/rocketmq/5.0.0/conf/broker.conf

  broker.conf

  brokerClusterName = DefaultCluster
  brokerName = broker-a
  brokerId = 0
  deleteWhen = 04
  fileReservedTime = 48
  brokerRole = ASYNC_MASTER
  flushDiskType = ASYNC_FLUSH
  
  # 不加无法访问
  brokerIP1=192.168.2.8
  
  # 自动创建主题
  autoCreateTopicEnable=true
  
  # nameserver地址
  namesrvAddr=192.168.2.8:9876

• 编写docker-compose.yml

  docker-compose.yml

  version: '3.8'
  services:
    namesrv:
      image: apache/rocketmq:5.0.0
      container_name: rocketmq-namesrv
      ports:
        - 9876:9876
      networks:
        - rocketmq
      command: sh mqnamesrv
  
    broker:
      image: apache/rocketmq:5.0.0
      container_name: rocketmq-broker
      ports:
        - 10909:10909
        - 10911:10911
        - 10912:10912
      environment:
        - NAMESRV_ADDR=rocketmq-namesrv:9876
      depends_on:
        - namesrv
      networks:
        - rocketmq
      volumes:
        - "E:/Docker/rocketmq/5.0.0/conf/broker.conf:/home/rocketmq/rocketmq-5.0.0/conf/broker.conf"
      command: sh mqbroker -c /home/rocketmq/rocketmq-5.0.0/conf/broker.conf
  
    dashboard:
      image: rocketmq-dashboard:1.0.1
      container_name: rocketmq-dashboard
      ports:
        - 9875:8082
      networks:
        - rocketmq
      volumes:
        - "E:/Docker/rocketmq/dashboard/:/app-nq/"
      command: java -jar /app-nq/rocketmq-dashboard.jar
  
  networks:
    rocketmq:
      driver: bridge

• 执行docker-compose -p rocketmq up -d编排容器
