   @chrsoo @sky-big @wolfstudy I think what @chrsoo request is an operator for the full lifecycle management for all the resources within a Pulsar instance. This includes both ClusterOperator and ResourceOperator. 
   
   A ClusterOperator is what @sky-big is doing and most of the *operators* are doing. It is used for setting up a cluster and managing the upgrade, downgrade and scaling up-and-down a cluster.
   
   A ResourceOperator is more about using *CRD* for provisioning *resources* within a Pulsar cluster. A *resource* such as a role (key and tokens), a tenant, a namespace, a topic, a function and etc. 
   
   Once everything is modeled as CRD, you can use kubernetes to provision both cluster and resources. Thus you can apply a GitOps patten in a CI/CD pipeline to manage everything.
   
   @chrsoo : this is kind of aligned with what we (StreamNative) are working on. We shall be able to share what we have done soon.
