Couple of things to know:
- Using a raspberry pi 4
- Running Unbuntu 20.04 image on ri4
- I use ZeroTier and SSH to connect remotely to the ri4
- I was able to run 3 containers: nodered, mosquito and portainer.
I’m having issues with different Zookeeper and/or Kafka images when trying to run/start the Kafka service. I wonder if I have to use a specific image due to the arm64 architecture since I’m using a ri4.
So far, I’ve used the general images:
- confluent, bitnami and wurstmeister.
Here’s a section of my docker-compose:
zookeeper:
image: confluent/zookeeper
container_name: zookeeper
environment:
- ZOOKEEPER_CLIENT_PORT=2181
kafka:
image: confluent/kafka
container_name: kafka
environment:
- KAFKA_ADVERTISED_HOST_NAME=kafka
- KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
- KAFKA_CREATE_TOPICS=mqtt-sensor-1
depends_on:
- zookeeper
restart: on-failure
I’m always getting this error from Kafka whenever I initiate a docker-compose up:
kafka | exec /usr/local/bin/kafka-docker.sh: exec format error
I’m not getting anything else. Any idea?

This seems to do the trick, with the ubuntu images (supports ARM64):
The Docker images you want are in the
confluentinc/
repo, and latest versions support multi-arch builds.
