本人安装版本：最新版(rocketmq-4.4.0),以下均对应4.4.0版本
一、docker部署RocketMQ
1、简易说明
在RocketMQ中，有三个关键组件：Namesrv（Name Server）、Broker和Console-ng（管理控制台）。
-
Namesrv（Name Server）：Namesrv是RocketMQ的命名服务，负责管理整个RocketMQ集群的路由信息。每个RocketMQ集群中都至少需要一个Namesrv实例。它维护了Broker的网络信息、Topic的路由规则以及Consumer的消费进度等元数据，并提供给Producer和Consumer使用。
-
Broker：Broker是RocketMQ的消息存储和处理节点，负责存储消息、处理消息的读写请求和转发消息等功能。在RocketMQ集群中，可以有多个Broker实例，各个Broker通过与Namesrv交互来维护消息的元数据和路由信息，以实现高可用、负载均衡的消息传输。
-
Console-ng（管理控制台）：Console-ng是RocketMQ官方提供的管理控制台，用于管理和监控RocketMQ集群。它提供了图形化界面，可以进行Topic、Consumer等的配置管理、消息查询与追踪、监控指标展示等操作。Console-ng对于集群的监控和运维非常有用。
这三个组件共同构成了RocketMQ的核心架构，并协同工作以实现高可用、高性能的消息传输和数据管理。您可以通过启动Namesrv、Broker来搭建一个RocketMQ集群，并使用Console-ng进行集群的管理与监控。
2、docker拉取RocketMQ镜像\RocketMQ控制台
拉取最新的RocketMQ，如果下载指定版本可以去docker官网查看
注：Namesrv、Broker均采用rocketmqinc/rocketmq同一个镜像
# 最新(rocketmq)
docker pull rocketmqinc/rocketmq
# 指定版本号(rocketmq)
docker pull rocketmqinc/rocketmq:<版本号>
# 最新(RocketMQ控制台)
docker pull pangliang/rocketmq-console-ng
3、获取RocketMQ配置文件
可以启动RocketMQ，然后从docker容器中拷贝出配置文件，拷出配置文件后启动的容器就可以删除了
docker run -d --name rmqnamesrv -p 9876:9876 rocketmqinc/rocketmq:latest sh mqnamesrv
# 进入容器(用于进入容器找到broker.conf 的位置)
docker exec -it 容器ID /bin/bash
# 从容器中下载文件到虚拟机
docker cp 容器ID:/opt/rocketmq-4.4.0/conf/broker.conf 虚拟机路径

5、docker启动RocketMQ
以下将配置文件、日志、存储均挂载在本地
# 1、namesrv
docker run -d -p 9876:9876 \
-v /mydata/rocketmq/namesrv/logs:/root/logs \
-v /mydata/rocketmq/namesrv/store:/root/store \
-v /mydata/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf \
--name rmqnamesrv \
rocketmqinc/rocketmq:latest sh mqnamesrv
# 2、broker
docker run -d -p 10911:10911 -p 10909:10909 \
-v /mydata/rocketmq/broker/logs:/root/logs \
-v /mydata/rocketmq/broker/store:/root/store \
-v /mydata/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf \
--name rmqbroker \
--add-host namesrv:172.16.234.150 \
-e "NAMESRV_ADDR=namesrv:9876" \
rocketmqinc/rocketmq:latest \
sh mqbroker -n namesrv:9876 \
-c /opt/rocketmq-4.4.0/conf/broker.conf autoCreateTopicEnable=true
# 3、Console-ng
docker run --name rocketmq-console \
-e "JAVA_OPTS=-Drocketmq.namesrv.addr=172.16.234.150:9876 \
-Dcom.rocketmq.sendMessageWithVIPChannel=false" \
-p 8080:8080 -t styletang/rocketmq-console-ng
6、进入RocketMQ控制台
地址(IP+rocketmq-console端口)：http://172.16.234.150:8080/#/
二、填坑经验
错误一: connect to <172.17.0.3:10909> failed
1、在启动Java项目后，发送MQ消息是报以下错误
2、RocketMQ控制台，集群地址显示为docker分配的IP
进入RocketMQ控制台，控制台显示的集群地址为172.17.0.3:10909，并非172.16.234.150:10909，172.17.0.3实际为docker内部分配的ID，需要此IP修改为虚拟机的IP
为了解决以上问题使用docker创建了一个网格【docker network create rocketmq-net + docker run -d --network rocketmq-net …】，但是没有解决此问题，实际导致此问题的是RocketMQ配置文件，请核查RocketMQ配置文件，或者采用上方提供的配置文件

错误二: maybe your broker machine memory too small
内存不足，以为是docker启动命令中未传内存信息，实际是虚拟机可用内存空间不足
Caused by: com.alibaba.rocketmq.client.exception.MQBrokerException: CODE: 14 DESC: service not available now, maybe disk full, CL: 0.99 CQ: -1.00 INDEX: -1.00, maybe your broker machine memory too small.
