URL: https://github.com/apache/rocketmq-externals/issues/569


   Knative is a kubernetes based platform for building, deploying and managing 
modern serverless applications. Knative to provide a set of middleware 
components that are essential to building modern, source-centric, and 
container-based applications that can run anywhere: on-premises, in the cloud, 
or even in a third-party data centre. Knative consists of the Serving and 
Eventing components. Eventing is a system that is designed to address a common 
need for cloud-native development and provides composable primitives to enable 
late-binding event sources and event consumers. Eventing also defines an event 
forwarding and persistence layer, called a Channel. Each channel is a separate 
Kubernetes Custom Resource.
   
   RocketMQ Channel is  to provide data persistence and event distribution for 
the Knative platform. The main functions of RocketMQ Channel are RocketMQ 
Cluster management (including cluster parameter configuration and topic 
maintenance), event reception, event storage, and event distribution. Instead 
of storing events directly, RocketMQ Channel stores events to the rocketmq 
cluster by calling the RocketMQ Go client. RocketMQ Channel is Kubertenes CRD 
and can be deployed through kubectl apply. RocketMQ Channel  includes three 
components: controller, dispatcher and clent go.
   
   This topic requires you to implement RocketMQ Channel, including
   1. Before implementing RocketMQ Channel, you need to learn RocketMQ Go 
Client and implement the required admin tool instructions.
   2. Implement RocketMQ Channel for Knative based on Apache RocketMQ.
   
   
Knative是一个基于kubernetes用于构建,部署和管理现代的无服务器应用程序的平台。Knative提供了一组中间件组件,这些组件对于构建可在任何地方运行以源为中心和基于容器的应用程序必不可少。Knative由服务和事件组件组成。事件处理旨在满足云原生开发的普遍需求,并提供可组合的原语以实现后期绑定事件源和事件使用者。事件还定义了事件转发和持久层,称为Channel。每个Channel都是一个单独的Kubernetes自定义资源。
   
   RocketMQ Channel主要定位是为Knative平台提供数据持久化以及事件分发。RocketMQ 
Channel主要功能有RocketMQ集群管理(包括集群参数配置、Topic维护)、事件接收、事件存储以及事件分发。RocketMQChannel不会直接存储事件,而是通过调用RocketMQ
 Go 客户端将事件存储到RocketMQ集群。RocketMQChannel是Kubertenes的CRD,可以通过kubectl apply 
部署。RocketMQChannel具体包括Controller、Dispatcher、Clent-Go三个组件。
   
   本题目希望你能实现一个RocketMQ Channel,包括
   1.根据RocketMQ Channel的需求,学习RocketMQ Go Client,并实现需要的Admin Tool指令
   2.实现RocketMQ Channel的相关组件。
