一、搭建Redis集群
具体安装请参考本人下面这篇文章
Kubernetes实战——基于Helm安装Redis主从模式_redis helm 部署-CSDN博客
1、安装redis
1、创建namespace
kubectl create ns redis2、安装redis、helm install redis ./redis/ -n redis3、查看资源
kubectl get po,svc -n redis 
2、测试连接
二、搭建RocketMq
1、下载资源
1、添加helm仓库helm repo add rocketmq-repo https://helm-charts.itboon.top/rocketmqhelm repo update rocketmq-repo2、查看仓库
helm search repo rocketmq3、拉取资源，这里选择集群版本helm pull rocketmq-repo/rocketmq-cluster 4、解压文件
tar -zxf rocketmq-cluster-12.3.2.tgz 2、安装
1、创建namespace
kubectl create ns rocketmq2、安装rocketmq
helm install rocketmq ./rocketmq-cluster/ -n rocketmq3、查看资源
kubectl get po,svc -n rocketmq3、查看dashboard
