kafka bootstrap broker disconnected using docker-compose - docker

Question

Good morning.
First of all, I've created a docker swarm with 2 physical hosts and an overlay network. In the same host I've created 2 containers (postgres and ambari servers) and one with ambari agent in which I'll install kafka, zookeeper, spark,... from ambari. The scope is installing several containers in several hosts, but I'm trying first like this as I'm not getting it working.
The fact is that once deployed with Ambari, I change kafka configuration to add advertised.host.name to the physical host's ip and advertised.port to 9092 to bind it to physical host's 9092 port.
When trying it, I'm always getting the following errors:
WARN Error while fetching metadata with correlation id 17 : {prueba2=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
If trying by sending to container's 6667 port
or
[2018-08-30 12:06:28,758] WARN Bootstrap broker 192.168.0.28:9092 disconnected (org.apache.kafka.clients.NetworkClient)
If trying to physical host's port 9092.
Thanks for help and please ask for any further information needed to help solving this problem.
EDIT1:
Configuration changed to the following properties.
and kafka-broker is not running. server.log is showing following trace:

If you're deploying Kafka within Docker, you need to configure the listener to be accessible if you want to be able to access it from outside your Docker network too. This article explains the details.
