# docker构建rockermq镜像 #

说明： RocketMQ的部署主要是broker和namesrv，broker是MQ的消息中转角色，负责存储消息，转发消息，一般称为Server。在 JMS 规范中称为 Provider。namesrv是一个几乎无状态节点，接受broker的Topic信息注册，为 producer 和 consumer 提供路由信息。

## 1、namesrv镜像 ##

创建目录

/home/qw/docker/rocketmq/namesrv

\#创建Dockerfile文件  
vi Dockerfile

FROM java:8
    
    ENV ROCKETMQ_VERSION 4.2.0
    
    ENV ROCKETMQ_HOME  /opt/rocketmq-${ROCKETMQ_VERSION}
    ENV JAVA_OPT " -Duser.home=/opt"
    
    WORKDIR  ${ROCKETMQ_HOME}
    
    RUN mkdir -p /opt/logs /opt/store
    
    RUN curl https://dist.apache.org/repos/dist/release/rocketmq/${ROCKETMQ_VERSION}/rocketmq-all-${ROCKETMQ_VERSION}-bin-release.zip -o rocketmq.zip \
              && unzip rocketmq.zip \
              && rm rocketmq.zip \
              && cd ${ROCKETMQ_HOME}/bin \
              && sed -i 's#-Xms[0-9]\+[gm]#-Xms256m#' runserver.sh \
              && sed -i 's#-Xmx[0-9]\+[gm]#-Xmx256m#' runserver.sh \
              && sed -i 's#-Xmn[0-9]\+[gm]#-Xmn128m#' runserver.sh \
              && sed -i 's#-XX:MetaspaceSize=[0-9]\+[gm]#-XX:MetaspaceSize=64m#' runserver.sh \
              && sed -i 's#-XX:MaxMetaspaceSize=[0-9]\+[gm]#-XX:MaxMetaspaceSize=128m#' runserver.sh \
              && chmod +x ./mqnamesrv
    
    CMD cd ${ROCKETMQ_HOME}/bin && sh mqnamesrv
    
    EXPOSE 9876
    
    VOLUME ["/opt/logs", "/opt/store"]

## 1.2、构建namesrv镜像 ##

\#构建镜像  
docker build -t manualcall/rocketmq-namesrv:4.2.0 .

## 1.3、查看namesrv镜像 ##

\#查看docker镜像列表  
docker images

\#查看manualcall/rocketmq-namesrv镜像信息  
docker inspect manualcall/rocketmq-namesrv:4.2.0

## 2、broker镜像 ##

创建目录

/home/qw/docker/rocketmq/broker

\#创建Dockerfile文件  
vi Dockerfile

FROM java:8
    
    ENV ROCKETMQ_VERSION 4.2.0
    
    ENV ROCKETMQ_HOME  /opt/rocketmq-${ROCKETMQ_VERSION}
    ENV JAVA_OPT " -Duser.home=/opt"
    
    WORKDIR  ${ROCKETMQ_HOME}
    
    RUN mkdir -p /opt/logs /opt/store
    
    RUN curl https://dist.apache.org/repos/dist/release/rocketmq/${ROCKETMQ_VERSION}/rocketmq-all-${ROCKETMQ_VERSION}-bin-release.zip -o rocketmq.zip \
              && unzip rocketmq.zip \
              && rm rocketmq.zip \
              && cd ${ROCKETMQ_HOME}/bin \
              && sed -i 's#-Xms[0-9]\+[gm]#-Xms256m#' runbroker.sh \
              && sed -i 's#-Xmx[0-9]\+[gm]#-Xmx256m#' runbroker.sh \
              && sed -i 's#-Xmn[0-9]\+[gm]#-Xmn128m#' runbroker.sh \
              && chmod +x ./mqbroker
    
    EXPOSE 10909 10911 10912
    
    VOLUME ["/opt/logs", "/opt/store"]
    
    CMD cd ${ROCKETMQ_HOME}/bin && sh mqbroker

\#构建镜像  
docker build -t manualcall/rocketmq-broker:4.2.0 .

\#查看manualcall/rocketmq-broker镜像信息  
docker inspect manualcall/rocketmq-broker:4.2.0

到此rocketmq主要的两个镜像搭建完成
