I tried with the M1 branch however it gives below logs in a loop.

fraud-detection-demo-kafka-cp-kafka-headless-1  | [main-SendThread(zoo1:2181)] INFO org.apache.zookeeper.ClientCnxn - Socket error occurred: zoo1/172.20.0.2:2181: Connection refused

Changing zookeper image and config as below solved the problem:

zookeeper:
    image: confluentinc/cp-zookeeper:7.3.0
    hostname: zookeeper
    container_name: zookeeper
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
