I've installed Confluent Kafka OSS using their official helm chart: https://github.com/confluentinc/cp-helm-charts
However, I would like to consume Kafka topics in a GCP Dataflow so this mean, I guess, that I need to make the Kafka pods available outside the K8s cluster.
I was not able to find a parameter into the helm chart to switch from ClusterIP to Node Balancers (for each broker, I guess)
Assuming that I will, how to restrict the access to GCP resources (eventually the same project in which the K8s cluster lies) only?
