是否需要单独部署controller

[wokwong]

提问： 在rocketmq-operator README.md 中没有介绍是否需要部署controller ，是否需要单独部署呢？谢谢

It depends on the way to organizing the broker cluster:

• By default, broker roles in a cluster are static, and Controller is unnecessary.
• If broker roles can be switched dynamically (ONLY supported in RocketMQ 5.x), Controller is required.

不好意思 ，忘记指明版本。 版本是：RocketMQ 5.0 使用operator部署到k8s。 如果RocketMQ 5.0集群要实现自动主从切换 需要额外部署controller，需要对controller额外做什么配置么？

• For Controller, you may find this example for reference. You should specify size (must be odd number), image name, resources and storage configurations.
• For Broker, set spec. ClusterMode as CONTROLLER enabling dynamical switching.

Could you provide the 5.0.0 version rocketmq_v1alpha1_rocketmq_cluster.yaml for us? If I want to enable the broker's controller mode. I don't know whether the image is the latest version or I just added the spec. ClusterMode as CONTROLLER is good enough for the auto failover version5 ?
