Answer 1

the solution in network we must network pointer to zookeeper and kafka the

solution is:

**

1. create new network by docker

**

docker network create kafka-net

2. and now involved your network into zookeeper and kafka like that:

 docker run -d\
--name zookeeper \
--network kafka-net
-p 2181:2181 \
jplock/zookeeper

and kafka like this:

docker run -d \
--name kafka \
--network kafka-net
-p 7203:7203 \
-p 9092:9092 \
-e KAFKA_ADVERTISED_HOST_NAME=127.0.0.1 \
-e ZOOKEEPER_IP=zookeeper \
