- 参考:
一、检索镜像
docker search rocketmq
检索具体版本
curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags | tr -d '[\[\]" ]' | tr '}' '\n' | awk -F: -v image='foxiswho/rocketmq' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'
查看当前镜像所有的版本shell命令
curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags\ | tr -d '[\[\]" ]' | tr '}' '\n'\ | awk -F: -v image='foxiswho/rocketmq' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'
二、创建Broker Server
docker run -d -p 9876:9876 --name rmqserver foxiswho/rocketmq:server-4.5.1
三、创建broker
docker run -d -p 10911:10911 -p 10909:10909\ --name rmqbroker --link rmqserver:namesrv\ -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt"\ -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m"\ foxiswho/rocketmq:broker-4.5.1
配置broker.conf
进入rmqbroker容器
docker exec -it rmqbroker /bin/bash cd /etc/rocketmq/ vi broker.conf
四、创建rocketmq console
docker run -d --name rmqconsole -p 8180:8080 --link rmqserver:namesrv\ -e "JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876\ -Dcom.rocketmq.sendMessageWithVIPChannel=false"\ -t styletang/rocketmq-console-ng
然后通过如下命令检查一下启动情况
docker ps|grep rocketmq

五、测试
由于我在宿主机安装rocketmq,测试如下:
#测试消息发送命令 sh tools.sh org.apache.rocketmq.example.quickstart.Producer
#测试消息接收命令 sh tools.sh org.apache.rocketmq.example.quickstart.Consumer
六、java样例
<dependency> <groupId>org.apache.rocketmq</groupId> <artifactId>rocketmq-client</artifactId> <version>4.9.2</version> </dependency>
消息发送(Producer端发送同步消息)
import org.apache.rocketmq.client.producer.DefaultMQProducer; import org.apache.rocketmq.client.producer.SendResult; import org.apache.rocketmq.common.message.Message; import org.apache.rocketmq.remoting.common.RemotingHelper; public class SyncProducer { public static void main(String[] args) throws Exception { // 实例化消息生产者Producer DefaultMQProducer producer = new DefaultMQProducer("zhuzeqing-1"); // 设置NameServer的地址 producer.setNamesrvAddr("192.168.23.131:9876"); // 启动Producer实例 producer.start(); for (int i = 0; i < 1; i++) { // 创建消息,并指定Topic,Tag和消息体 Message msg = new Message("zhuzeqing-1-Topic" /* Topic */, "TagA" /* Tag */, ("hello,rocketmq --" + i).getBytes(RemotingHelper.DEFAULT_CHARSET) /* Message body */ ); // 发送消息到一个Broker SendResult sendResult = producer.send(msg); // 通过sendResult返回消息是否成功送达 System.out.printf("%s%n", sendResult); } // 如果不再发送消息,关闭Producer实例。 producer.shutdown(); } }
消费消息
import java.util.List; import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer; import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext; import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus; import org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently; import org.apache.rocketmq.client.exception.MQClientException; import org.apache.rocketmq.common.message.MessageExt; public class Consumer { public static void main(String[] args) throws InterruptedException, MQClientException { // 实例化消费者 DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("zhuzeqing-1"); // 设置NameServer的地址 consumer.setNamesrvAddr("192.168.23.131:9876"); // 订阅一个或者多个Topic,以及Tag来过滤需要消费的消息 consumer.subscribe("zhuzeqing-1-Topic", "*"); // 注册回调实现类来处理从broker拉取回来的消息 consumer.registerMessageListener(new MessageListenerConcurrently() { public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) { System.out.printf("%s Receive New Messages: %s %n", Thread.currentThread().getName(), msgs); // 标记该消息已经被成功消费 return ConsumeConcurrentlyStatus.CONSUME_SUCCESS; } }); // 启动消费者实例 consumer.start(); System.out.printf("Consumer Started.%n"); } }
七、其他
查看rmqbroker IP
docker inspect rmqbroker
Broker容器中默认的配置文件的路径为
/etc/rocketmq/broker.conf
