Answer 1

actually there is no namespace called "osm" everything running on default namespace

Refer kube.netes documentation .

As the error says, there's no service kafka in an osm namespace (whether that exists, or not), that can be reached. Remove .osm from that address, or change it to .default , assuming that there really is a Service named kafka available at port 9092
