# Each Kafka listener will be confgiured for each ip/domain with a unique port #
# ex localhost:port will have local host access to docker container and external host services #
# ex kafka:port will only have access internally to all containers within a same network #
# ex ip:port will have external access from other host to this host #

    ## COnfigure listener here like ip:port for external access and localhost:port for host only access
    ## or configure localhost:port1 & ip:port2 together for enabling host as well as external access both
