Using standalone topic/user operator with Redpanda (without zoopkeeper)

[ee07dazn]

Hello

I have an up/running Kafka cluster provided by redpanda - obviously this does not include any zookeeper etc..
I have been able to setup kafka connect using StrimziOperator and talk to redpanda cluster. I am trying to see if I can use the Topic (&User) Operator to mange topics/users here.
Following the docs, I have updated the deployment yaml file and provided the relevant creds/env variables.

I first tried by commenting out the STRIMZI_ZOOKEEPER_CONNECT variable but that threw an error suggesting this needs to be set. So it just set as blank..While the error is gone, unfortunately, the topic operator is crashing but i can't seem to see any errors in the message that can help me to debug the issue.

I have attached the logs here..please let me know if there is anything else i can provide here to help me out or confirm one way or another whether - this will be incompatible with redpanda ?

Thanks

Strimzi is designed to work with the Apache Kafka project. Redpanda is not Apache Kafka and will offer only limited compatibility, so different parts of Strimzi might not work. The Topic Operator relies on ZooKeeper and on the way it is used in Apache Kafka. You cannot get it working just by commenting out the things the operator needs.

Thanks for confirming!
