Docker Compose Getting Started with JAVA RocketMQ

Motivation

Just want to try Docker Compose...

Prerequisites

JAVA JMS: RocketMQ NameServer Broker Cluster
https://ben-bai.blogspot.com/2019/10/java-jms-rocketmq-nameserver-broker.html


Simple Note

Go to Dockerfile folder,

Add the docker-compose.yml below into it
https://github.com/benbai123/JSP_Servlet_Practice/blob/master/Practice/JAVA/JMS/RocketMQ/RocketMQCluster/docker-compose.yml

then run docker-compose up

Docker Compose will build image and run container with specified config value

Shortly,

Dockerfile define "how to create the container"

docker-compose.yml describe "how to config/run containers"

JAVA JMS: RocketMQ NameServer Broker Cluster

Simple Note

After bind necessary ports
(see Connect to VirtualBox Guest Machine from Host OS with NAT Port Forwarding)

Creat Docker Image with Dockerfile
(see Create Dockerfile for Docker Image of RocketMQ NameServer)

Can give it a try finally...

Testing Video

The command for start broker is slightly different, add -c to use specific config and specify multiple nameServer address

e.g.

mqbroker.cmd -c ../conf/2m-2s-sync/broker-a.properties -n localhost:9487;localhost:9478 autoCreateTopicEnable=true

All files in the test project

JAVA JMS: RocketMQ Getting Started

Simple Notes

1. Download NameServer and Broker
  Go to archive.apache.org
  Download release zip file
  (I choose 4.5.2/rocketmq-all-4.5.2-bin-release.zip)

2. Extract it
  Assume I extract it to
  D:\things\Downloads\rocketmq\rocketmq-all-4.5.2-bin-release

3. Start NameServer
  Open cmd, run commands below

  cd D:\things\Downloads\rocketmq\rocketmq-all-4.5.2-bin-release\bin
  D:
  set JAVA_HOME=D:\things\programs\Java\jdk1.8.0_221
  set ROCKETMQ_HOME=D:\things\Downloads\rocketmq\rocketmq-all-4.5.2-bin-release\
  mqnamesrv.cmd -n localhost:9876

4. Start Broker
  Open cmd, run commands below

  cd D:\things\Downloads\rocketmq\rocketmq-all-4.5.2-bin-release\bin
  D:
  set JAVA_HOME=D:\things\programs\Java\jdk1.8.0_221
  set ROCKETMQ_HOME=D:\things\Downloads\rocketmq\rocketmq-all-4.5.2-bin-release\
  mqbroker.cmd -n localhost:9876 autoCreateTopicEnable=true

5. Write Consumer and Producer for test

  TestConsumer.java ; TestProducer.java ; and this is a maven project, so pom.xml
  Run TestConsumer and TestProducer, you will see something in the console.
