I wasn't able to find an answer for this, and I'm facing some difficulties while trying to implement it.
Does confluent command only is able to run multiple brokers + Zookeeper? Is it possible to build a kafka cluster consist of 3 nodes, using Confluent CLI?
Thanks.
No, it does not support multi-node clusters.
It only runs a single localhost kafka-server-start and zookeeper-server-start commands.
Additionally, as mentioned on the documentation page
meant for development purposes only and is not suitable for a production environment. The data that are produced are transient and are intended to be temporary.
By "production environment" here, it is implied as multiple servers.
