consumer receives no message from Kafka
1
I am using docker-compose.yml to set up multi-layer web app.
batch:
image: tp33/django
container_name: batch
links:
- kafka:kafka
- es:es
depends_on:
- kafka
- es
volumes:
- ./batch_layer:/app
networks:
- mynet
command: bash -c "cd /app && python consumer.py"
kafka:
image: spotify/kafka
container_name: kafka
environment:
ADVERTISED_HOST: kafka
ADVERTISED_PORT: 9092
hostname: kafka
networks:
- mynet
The batch layer is used as the consumer in Kafka, but it doesn't receive any message from queue. If I use "docker run -it --name batch --link kafka:kafka --link es:es --network=mynet tp33/django" instead of docker-compose to set up batch layer, the consumer can receive messages.
Could anyone figure out the difference?

The primary difference is that you're hard coding the command in the compose file and you're not using interactive mode compared torun -it, but without your Python code, it's hard to really say since this isn't a Minimal, Complete, and Verifiable example

did you dodocker-compose runordocker-compose up?

I am using docker-compose up. I just fixed the problem by putting the KafkaConsumer() in try-except block and looping until successfully connecting to kafka from batch layer. But I still cannot figure out the difference

One thing that you can do is to make sure that kafka is actually fully running before start the command on the batch. You can see an example here docs.docker.com/compose/startup-order that waits for postgresql to be running first
