Set up kafka without zookeeper

[teng1]

Is your proposal related to a problem?

Hi,
I have a KRaft enabled kafka 3.0.0 cluster running in K8s using a very similar setup to the following https://debezium.io/blog/2021/08/31/going-zookeeperless-with-debezium-container-image-for-apache-kafka/

I deployed the Kafka UI as a separate service, i'm able to access the cluster and view Brokers but not able to create topics and it seems like its not supported due to expecting zookeeper, would be great if support could be included for the new zookeeperless mode

Describe the solution you'd like

Support within application.yml file for KRaft enabled clusters
Thanks!

@teng1 try this config

    # ...
    environment:
        KAFKA_CLUSTERS_0_NAME: "local"
        KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS: "kafka1:19092" # or "broker:19092"
        # KAFKA_CLUSTERS_0_ZOOKEEPER: "zoo1:2181" <==== comment this
    # ...

@Haarolean But this configuration does not support the full-fledged work with Kafka

@pikhovkin Which behaviour is expected to have without a zookeeper?

[pikhovkin]

I am not an expert in KRaft either. Kafka-ui with this config works, but not stable, for example, not always the first time you create a topic.
