dashboard

Dockerfile

FROM openjdk:8-jdk
VOLUME /tmp
ADD rocketmq-dashboard-1.0.0.jar rocketmq-dashboard.jar
RUN sh -c 'touch /rocketmq-dashboard.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -jar /rocketmq-dashboard.jar" ]

##步骤

#版本V5.0.0
1.准备前置文件
namesrv Dockerfile：
broker Dockerfile:
dashboard Dockerfile:
下载地址
https://github.com/apache/rocketmq-dashboard/tree/release-1.0.0

Maven打包生成rocketmq-dashboard-1.0.0.jar与Dockerfile放置同一目录下。
2.构建镜像
namesrv
docker build -f Dockerfile -t rmq-namesrv:5.0.0 .

broker
docker build -f Dockerfile -t rmq-broker:5.0.0 .

dashboard
docker build -t rmq-dashboard:laster .

3.运行容器

namesrv
docker run -d --name rmq-namesrv -e “JAVA_OPT_EXT=-Xms512M -Xmx512M -Xmn128M” -p 9876:9876 -v /localdata/rocketmq/logs:/home/rocketmq/logs -v /localdata/rocketmq/store:/home/rocketmq/store rmq-namesrv:5.0.0

broker
docker run -d --name rmq-broker -e “JAVA_OPT_EXT=-Xmx512M -Xmx512M -Xmn128M” -p 10909:10909 -p 10911:10911 -p 10912:10912 -v /localdata/rocketmq/conf/broker.conf:/home/rocketmq/conf/broker.conf -v /localdata/rocketmq/logs:/home/rocketmq/logs -v /localdata/rocketmq/store:/home/rocketmq/store rmq-broker:5.0.0 bash /home/rocketmq/bin/mqbroker -c /home/rocketmq/conf/broker.conf -n **#ip **:9876 autoCreateTopicEnable=true

dashboard
docker run --name rmq-dashboard -e “JAVA_OPTS=-Drocketmq.namesrv.addr=**#ip **:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false” -p 8099:8080 -t rmq-dashboard:laster

附broker.conf

# 所属集群名称，如果节点较多可以配置多个
brokerClusterName = DefaultCluster
#broker名称，master和slave使用相同的名称，表明他们的主从关系 
brokerName = broker-a
#0表示Master，大于0表示不同的
slave brokerId = 0
#表示几点做消息删除动作，默认是凌晨4点 
deleteWhen = 04
#在磁盘上保留消息的时长，单位是小时 
fileReservedTime = 48
#有三个值：SYNC_MASTER，ASYNC_MASTER，SLAVE；同步和异步表示Master和Slave之间同步数据的机 制；
brokerRole = ASYNC_MASTER
#刷盘策略，取值为：ASYNC_FLUSH，SYNC_FLUSH表示同步刷盘和异步刷盘；SYNC_FLUSH消息写入磁盘后 才返回成功状态，ASYNC_FLUSH不需要；
flushDiskType = ASYNC_FLUSH
# 设置broker节点所在服务器的ip地址 
brokerIP1 = {broker_ip}
#剩余磁盘比例 
diskMaxUsedSpaceRatio=99
#自动创建topic
autoCreateTopicEnable=true

broker.conf中{broker_ip} 替换为当前服务器ip
