I am new to docker and I'm having a problem running a Kafka broker inside a Docker container. I developed spring boot application with kafka,producer and consumer in the same application . application running successfully without docker , but when I try to run it through docker container on my host machine give me this error:

 org.apache.kafka.clients.NetworkClient   : [Producer clientId=producer-1] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.

org.apache.kafka.clients.NetworkClient   : [Consumer clientId=consumer-group_id-1, groupId=group_id] Bootstrap broker localhost:9092 (id: -1 rack: null) disconnected

I used spring boot 2.4.2 and kafka_2.7.0

Steps I followed:

1-I build docker image for spring boot application.

2-I create docker-compose.yml to run zookeeper and kafka services as following:

version: '3'
services:
zookeeper:
image: wurstmeister/zookeeper
ports:
  - "2181:2181"     
kafka:
  image: wurstmeister/kafka
build:
  context: .
  dockerfile: Dockerfile
ports:
  - "9092:9092"
environment:
  KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092
  KAFKA_LISTENERS: PLAINTEXT://0.0.0.0:9092
  KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
  KAFKA_MESSAGE_MAX_BYTES: 2000000
  KAFKA_CREATE_TOPICS: "Topic1:1:1"
volumes:
  - /var/run/docker.sock:/var/run/docker.sock
depends_on:
  - zookeeper

3- Then I execute the docker-compose.yml: docker-compose up -d

4- Finally I run spring boot app image: docker run -p 8080:8080 spring-boot-app .

This is my client config(spring boot app): application.properties:

Consumer configuration

  #spring.kafka.consumer.bootstrap-servers=localhost:9092

  spring.kafka.consumer.group-id==group_id

  spring.kafka.consumer.auto-offset-reset=earliest

  spring.kafka.consumer.key-deserializer= 
org.apache.kafka.common.serialization.StringDeserializer

  spring.kafka.consumer.value-deserializer= org.apache.kafka.common.serialization.StringDeserializer

Producer configuration

  #spring.kafka.producer.bootstrap-servers=localhost:9092

  spring.kafka.producer.key-serializer=   org.apache.kafka.common.serialization.StringSerializer

  spring.kafka.producer.value-serializer= org.apache.kafka.common.serialization.StringSerializer
