Im trying to setup my cluster with elk and kafka inside docker containers, but always logstash cant consume data from the kafka. Producer based on my local machine, not inside docker. I appriciate any help.

docker-compose:

  zoo1:  image: confluentinc/cp-zookeeper  restart: always  container_name: zoo1  ports:    - "2181:2181"  environment:    - ZOO_MY_ID=1    - ZOO_SERVERS=2181    - ZOOKEEPER_CLIENT_PORT=2181    - ALLOW_ANONYMOUS_LOGIN=yes       kafka:      image: confluentinc/cp-kafka      hostname: kafka      container_name: kafka      depends_on:        - zoo1      ports:        - "9092:9092"      environment:        KAFKA_BROKER_ID: 1        KAFKA_ZOOKEEPER_CONNECT: zoo1:2181        KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1        KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT        # KAFKA_LISTENERS: PLAINTEXT_HOST://0.0.0.0:9092, PLAINTEXT://kafka:29092        KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT        KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9093,PLAINTEXT_HOST://localhost:9092  

logstash.conf:

input {      kafka {          topics => ["topic-ex"]          bootstrap_servers => "localhost:9092"      }  }
