确认安装前已经安装好StorageClass，可参考：https://blog.csdn.net/u011943534/article/details/100887530

1、准备jdk镜像，并拷贝到服务器

docker pull java:8-alpine

2、制作rocketmq镜像
下载地址：https://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/
将”rocketmq-all-4.8.0-bin-release.zip”拷贝至服务器，解压
修改bin/runbroker.sh,将内存调整为适当（比如调小）

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m"

编写Dockerfile-rocketmq:

FROM java:8-alpine
 
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
 
ENV LANG en_US.UTF-8
 
ADD rocketmq-all-4.8.0-bin-release /usr/local/rocketmq-all-4.8.0-bin-release
RUN mv /usr/local/rocketmq-all-4.8.0-bin-release /usr/local/rocketmq-4.8.0 \
&& mkdir -p /data/rocketmq/store
 
CMD ["/bin/bash"]

docker build -f Dockerfile-rocketmq -t 172.16.10.190:80/library/rocketmq:4.8.0 .
docker push 172.16.10.190:80/library/rocketmq:4.8.0

3、制作nameserver镜像
使用第三步的rocketmq-all-4.8.0-bin-release
在conf/下添加namesrv.properties
内容为：

listenPort=20901

编写Dokerfile-namesrv:

FROM java:8-alpine
 
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
 
ENV LANG en_US.UTF-8
 
ADD rocketmq-all-4.8.0-bin-release /usr/local/rocketmq-all-4.8.0-bin-release
RUN mv /usr/local/rocketmq-all-4.8.0-bin-release /usr/local/rocketmq-4.8.0
 
WORKDIR /usr/local/rocketmq-4.8.0
CMD ["/usr/local/rocketmq-4.8.0/bin/mqnamesrv","-c","/usr/local/rocketmq-4.8.0/conf/namesrv.properties"]

docker build -f Dockerfile-nameserver -t 172.16.10.190:80/library/rocketmq-namesrv:4.8.0 .
docker push 172.16.10.190:80/library/rocketmq-namesrv:4.8.0

4、制作rocketmq-ui镜像
下载源码：
git clone https://github.com/apache/rocketmq-externals.git
下载maven:
wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

tar -zvxf rocketmq-externals.tar.gz

将本目录下的”application.properties“中内容替换到rocketmq-externals/rocketmq-console/src/main/resources/application.properties中
编写Dockerfile-ui

FROM java:8-alpine
 
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
 
ENV LANG en_US.UTF-8
ENV MAVEN_HOME /usr/local/maven
ENV PATH $PATH:$MAVEN_HOME/bin
 
ADD rocketmq-externals /usr/local/rocketmq-externals
ADD apache-maven-3.3.9 /usr/local/apache-maven-3.3.9
RUN mv /usr/local/apache-maven-3.3.9 /usr/local/maven
 
WORKDIR /usr/local/rocketmq-externals/rocketmq-console/
RUN mvn clean package -Dmaven.test.skip=true
 
WORKDIR /usr/local/rocketmq-externals/rocketmq-console/target
EXPOSE 8080
CMD ["nohup","java","-jar","rocketmq-console-ng-1.0.0.jar","&"]

5、准备configmap
broker-a.properties:

brokerClusterName=rocketmq-cluster
brokerName=broker-a
brokerId=0
namesrvAddr=mq-namesrv-0.mq-namesrv.default.svc.cluster.local:20901
defaultTopicQueueNums=4
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
listenPort=20911
deleteWhen=04
fileReservedTime=120
mapedFileSizeCommitLog=1073741824
mapedFileSizeConsumeQueue=300000
diskMaxUsedSpaceRatio=88
storePathRootDir=/data/rocketmq/store
maxMessageSize=65536
brokerRole=MASTER

broker-a-s.properties:

brokerClusterName=rocketmq-cluster
brokerName=broker-a
brokerId=1
namesrvAddr=mq-namesrv-0.mq-namesrv.default.svc.cluster.local:20901
defaultTopicQueueNums=4
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
listenPort=20911
deleteWhen=04
fileReservedTime=120
mapedFileSizeCommitLog=1073741824
mapedFileSizeConsumeQueue=300000
diskMaxUsedSpaceRatio=88
storePathRootDir=/data/rocketmq/store
maxMessageSize=65536
brokerRole=SLAVE
flushDiskType=SYNC_FLUSH

broker-b.properties:

brokerClusterName=rocketmq-cluster
brokerName=broker-b
brokerId=0
namesrvAddr=mq-namesrv-0.mq-namesrv.default.svc.cluster.local:20901
defaultTopicQueueNums=4
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
listenPort=20911
deleteWhen=04
fileReservedTime=120
mapedFileSizeCommitLog=1073741824
mapedFileSizeConsumeQueue=300000
diskMaxUsedSpaceRatio=88
storePathRootDir=/data/rocketmq/store
maxMessageSize=65536
brokerRole=MASTER
flushDiskType=SYNC_FLUSH

broker-b-s.properties:

brokerClusterName=rocketmq-cluster
brokerName=broker-b
brokerId=1
namesrvAddr=mq-namesrv-0.mq-namesrv.default.svc.cluster.local:20901
defaultTopicQueueNums=4
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
listenPort=20911
deleteWhen=04
fileReservedTime=120
mapedFileSizeCommitLog=1073741824
mapedFileSizeConsumeQueue=300000
diskMaxUsedSpaceRatio=88
storePathRootDir=/data/rocketmq/store
maxMessageSize=65536
brokerRole=SLAVE
flushDiskType=SYNC_FLUSH

根据以上文件生成configmap:

kubectl create configmap rocketmq-config --from-file=broker-a.properties --from-file=broker-b.properties --from-file=broker-a-s.properties --from-file=broker-b-s.properties  -n default

6、准备服务文件
