RocketMQ-dockefile制作镜像过程（一学就废）,centos,docker
开始编写rmqnamesrv的dockerfile

FROM java:openjdk-8u111-alpine
ENV ROCKETMQ_VERSION 5.1.3
ENV ROCKETMQ_HOME /opt/rocketmq-${ROCKETMQ_VERSION}
WORKDIR ${ROCKETMQ_HOME}
RUN set -x && rm -f /etc/localtime && ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone
ADD bin ${ROCKETMQ_HOME}/bin
ADD conf ${ROCKETMQ_HOME}/conf
ADD lib ${ROCKETMQ_HOME}/lib
RUN mkdir -p /opt/logs /opt/store
VOLUME /opt/logs /opt/store
EXPOSE 9876
RUN  chmod +x /opt/rocketmq-5.1.3/bin/mqnamesrv
CMD cd ${ROCKETMQ_HOME}/bin && export JAVA_OPT="-Duser.home=/opt -Xms512M -Xmx512M -Xmn128m " && sh mqnamesrv

开始编写rmqbroker的dockerfile

FROM java:openjdk-8u111-alpine
ENV ROCKETMQ_VERSION 5.1.3
ENV ROCKETMQ_HOME /opt/rocketmq-${ROCKETMQ_VERSION}
WORKDIR ${ROCKETMQ_HOME}
RUN set -x && rm -f /etc/localtime && ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone
ADD bin ${ROCKETMQ_HOME}/bin
ADD conf ${ROCKETMQ_HOME}/conf
ADD lib ${ROCKETMQ_HOME}/lib
RUN mkdir -p /opt/logs /opt/store
VOLUME /opt/logs /opt/store
EXPOSE 10909 10911
RUN chmod +x bin/mqbroker
CMD cd ${ROCKETMQ_HOME}/bin && export JAVA_OPT="-Duser.home=/opt -server -Xms512M -Xmx512M -Xmn128m" && sh mqbroker -n ${NAMESRV_ADDR} -c ../conf/broker.conf

生成镜像

docker build -f 指定你编写的dockerfile文件 -t 镜像name:版本 .

查看我实验生成的images

命令启动rockermq服务
这里NAMESRV_ADDR=1.1.1.1:9876是需要指定你安装的rmqnamesrv的ip+端口，-v挂载的日志以及对于的配置。

docker run -d -p 9876:9876 --name rmqnamesrv --restart=always rocketmq-namesrv:5.1.3

docker run -d -p 10911:10911 -p 10909:10909 --name rmqbroker --restart=always  -e "NAMESRV_ADDR=1.1.1.1:9876"  -v /opt/rocketmq/logs:/opt/logs -v /opt/rocketmq/store:/opt/store -v /home/conf/brocker.conf:/opt/rocketmq-5.1.3/conf/brocker.conf --link rmqnamesrv

对应brocker的配置文件：

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1=1.1.1.1 #配置服务器ip
autoCreateTopicEnable=true

问题点：
如果容器启动，查看日志发现是killed的情况，说明你的运行空间不够！要限制服务的内存使用！实验是加了8g内存去验证的

说明我们JAVA_OPTS 指定没有生效！
解决方案启动容器限制一下：

-e JAVA_OPT_EXT = -server -Xms128m -Xmx128m -Xmn128m

docker-compose启动

  rmqnamesrv:
    restart: always
    image: rmqnamesrv:5.1.3
    container_name: rmqnamesrv
    ports:
      - 9876:9876
    environment:
      JAVA_OPT_NXT: "-Duser.home=/opt -Xms512M -Xmx512M -Xmn128m"
  rmqbroker:
    restart: always
    image: rmqbroker:5.1.3
    container_name: rmqbroker
    ports:
      - 10909:10909
      - 10911:10911
    volumes:
      - /home/rocketmq/logs:/opt/logs
      - /home/rocketmq/store:/opt/store
      - /home/rocketmq/conf/broker.conf:/opt/rocketmq-5.1.3/conf/broker.conf
    environment:
        NAMESRV_ADDR: "rmqnamesrv:9876"
        JAVA_OPT_EXT: "-Duser.home=/opt -server -Xms512M -Xmx512M -Xmn128m"
    depends_on:
      - rmqnamesrv
