I have a Spring Boot application which worked fine with Kafka in a container but when I containerize the Spring Boot application it won't work.
This is the docker-compose file with which I created
version: "3.4"
services:
zookeeper:
image: bitnami/zookeeper
restart: always
container_name: "zookeeper"
ports:
- "2181:2181"
volumes:
- "zookeeper_data:/bitnami"
environment:
- ALLOW_ANONYMOUS_LOGIN=yes
kafka:
image: bitnami/kafka
ports:
- "9092:9092"
restart: always
container_name: "kafka"
volumes:
- "kafka_data:/bitnami"
environment:
- KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
- ALLOW_PLAINTEXT_LISTENER=yes
- KAFKA_LISTENERS=PLAINTEXT://:9092
- KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092
depends_on:
- zookeeper
volumes:
zookeeper_data:
driver: local
kafka_data:
driver: local
The application.yml of the Spring Boot application
server:
port: 5001
spring:
jpa:
database-platform: org.hibernate.dialect.MySQL8Dialect

The dockerfile with which I created the image of the app:
FROM openjdk:11
COPY target/project-service-1.jar project-service-1.jar
EXPOSE 5001
ENTRYPOINT ["java", "-jar" , "project-service-1.jar"]
The containers of kafka and data bases are running fine :
This is the command which i use to run the spring boot app container :
docker run --name project-service\
--network techbankNet\
-p 5001:5001\
--link mysql-container:mysql\
--link mongo-container:mongo\
--link adminer:adminer\
--link kafka:kafka project-service

CodePudding user response：
You should put project-service (and adminer, mongo, and mysql) in the same Docker Compose file as Kafka and not use docker run.
This will create a default bridge network where the containers can talk to each other.
Or you need to attach techbankNet Docker network to the Kafka service in the compose file.
