-1. Assuming you already have Confluent installed on OCI using this Github repo.  Let's create a topic using Confluent Control Center UI or command line or REST API.   **example: kafka_oci_object_storage_test.**

 I am using the REST API, so you can run it from anywhere as far as confluent worker nodes (cf-worker-1) are reachable.
