操作步驟如下：
前提：已經安裝了docker
1.docker search rocketmq
2.docker pull rocketmqinc/rocketmq
3. 創建 mq 配置文件 broker.conf，文件放置到 /opt/rocketmq/conf ，配置如下:
brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1 = x.x.x.x
4.創建如下文件夾：/opt/rocketmq/logs，/opt/rocketmq/store，最后創建 docker-compose.yml 文件，配置如下：version: '2'
version: '2'
services:
namesrv:
image: rocketmqinc/rocketmq
container_name: rmqnamesrv
ports:
- 9876:9876
volumes:
- /opt/rocketmq/logs:/home/rocketmq/logs
- /opt/rocketmq/store:/home/rocketmq/store
command: sh mqnamesrv
broker:
image: rocketmqinc/rocketmq
container_name: rmqbroker
ports:
- 10909:10909
- 10911:10911
- 10912:10912
volumes:
- /opt/rocketmq/logs:/home/rocketmq/logs
- /opt/rocketmq/store:/home/rocketmq/store
- /opt/rocketmq/conf/broker.conf:/opt/rocketmq/conf/broker.conf
#command: sh mqbroker -n namesrv:9876
command: sh mqbroker -n namesrv:9876 -c ../conf/broker.conf
depends_on:
- namesrv
environment:
- JAVA_HOME=/usr/lib/jvm/jre
console:
image: styletang/rocketmq-console-ng
container_name: rocketmq-console-ng
ports:
- 8087:8080
depends_on:
- namesrv
environment:
- JAVA_OPTS= -Dlogging.level.root=info -Drocketmq.namesrv.addr=rmqnamesrv:9876
- Dcom.rocketmq.sendMessageWithVIPChannel=false
5.配置完成之后，運行 docker-compose up 啟動三個容器，啟動成功后，訪問 ip:8087，查看 mq 外部控制台，如果可以看到以下信息，rocketmq 服務啟動成功。
