guys, for a local confluent via docker-compose deployment (development), have anyone done it using multiple brokers ? would love a copy of the docker compose file if I may. Also curious howI would then “expose” my multiple brokers to my client. G ---

Hi there Looks good, I will try. some questions though… where we are not exposing a port externally, why are we listing it under ports: and incrementing an internal and external number. ie: broker01: ports: - 9092:9092 - 9101:9101 - 29092:29092 environment: KAFKA\_LISTENERS: ‘PLAINTEXT://broker01:29092,CONTROLLER://broker01:29193,PLAINTEXT\_HOST://[0.0.0.0:9092](http://0.0.0.0:9092)’ KAFKA\_ADVERTISED\_LISTENERS: ‘PLAINTEXT://broker01:29092,PLAINTEXT\_HOST://localhost:9092’ broker02: ports: - 9093:9093 - 9102:9102 - 29093:29093 environment: KAFKA\_LISTENERS: ‘PLAINTEXT://broker02:29093,CONTROLLER://broker02:29194,PLAINTEXT\_HOST://[0.0.0.0:9093](http://0.0.0.0:9093)’ KAFKA\_ADVERTISED\_LISTENERS: ‘PLAINTEXT://broker02:29093,PLAINTEXT\_HOST://localhost:9093’ why not just use 29092. they private on the host. I understand ie 9092 that we expose to the localhost and where we expose to 0.0.0.0, so for boker01 we use localhost:9092 and broker host we use localhost:9093 etc. G ---

Hi there Ok, this does not seem to have worked, If I create 3 topics, one through each of the brokers only the broker to which the control center points reflects the topic. If I say query each broker about what topics it knows about it only shows the topic created using it, so not acting like a 3 node/broker cluster. G ---

think i got it working, agree on the topic will only reside on one node, but all brokers must still know about all topics to be able to redirect traffic to who ever owns that topic from a leader perspective. ```auto KAFKA_CONTROLLER_QUORUM_VOTERS: "1001@broker01:29193,1002@broker02:29194,1003@broker03:29195" ``` ---
