Unable to establish connection between Zookeeper and Kafka on Apple M1 using docker-compose - apache-kafka

Question

I am trying to run Kafka + Zookeeper through docker-compose.yml
`version: '3'
services:
zookeeper:
image: zookeeper:3.4.9
hostname: zookeeper
ports:
- "2181:2181"
environment:
ZOO_MY_ID: 1
ZOO_PORT: 2181
# ZOO_SERVERS: server.1=zookeeper:2888:3888;2181
volumes:
- ./data/zookeeper/data:/data
- ./data/zookeeper/datalog:/datalog
kafka1:
image: confluentinc/cp-kafka:5.3.0
hostname: kafka1
ports:
- "9091:9091"
environment:
KAFKA_ADVERTISED_LISTENERS: LISTENER_DOCKER_INTERNAL://kafka1:19091,LISTENER_DOCKER_EXTERNAL://${DOCKER_HOST_IP:-127.0.0.1}:9091
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: LISTENER_DOCKER_INTERNAL:PLAINTEXT,LISTENER_DOCKER_EXTERNAL:PLAINTEXT
KAFKA_INTER_BROKER_LISTENER_NAME: LISTENER_DOCKER_INTERNAL
KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"
KAFKA_BROKER_ID: 1
KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
volumes:
- ./data/kafka1/data:/var/lib/kafka/data
depends_on:
- zookeeper
However, Kafka is unable to connect with the ZooKeeper
kafka101-kafka1-1 | [main-SendThread(zookeeper:2181)] INFO org.apache.zookeeper.ClientCnxn - Socket error occurred: zookeeper/172.19.0.2:2181: Connection refused
kafka101-kafka1-1 | [main-SendThread(zookeeper:2181)] INFO org.apache.zookeeper.ClientCnxn - Opening socket connection to server zookeeper/172.19.0.2:2181. Will not attempt to authenticate using SASL (unknown error)
I checked and confirmed that the Zoo keeper is running
ps -ef | grep zookeeper
1 zookeepe 0:19 {java} /usr/bin/qemu-x86_64 /usr/lib/jvm/java-1.8-openjdk/jre/bin/java /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /zookeeper-3.4.9/bin/../build/classes:/zookeeper-3.4.9/bin/../build/lib/*.jar:/zookeeper-3.4.9/bin/../lib/slf4j-log4j12-1.6.1.jar:/zookeeper-3.4.9/bin/../lib/slf4j-api-1.6.1.jar:/zookeeper-3.4.9/bin/../lib/netty-3.10.5.Final.jar:/zookeeper-3.4.9/bin/../lib/log4j-1.2.16.jar:/zookeeper-3.4.9/bin/../lib/jline-0.9.94.jar:/zookeeper-3.4.9/bin/../zookeeper-3.4.9.jar:/zookeeper-3.4.9/bin/../src/java/lib/*.jar:/conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /conf/zoo.cfg
The zoo configuration looks like this:
clientPort=2181
dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
Telnet output directly from zookeeper is :
zookeeper-3.4.9 # telnet localhost 2181
telnet: can't connect to remote host (127.0.0.1): Connection refused
ping to zookeeper host in kafka1
> ping zookeeper
PING zookeeper (172.19.0.2) 56(84) bytes of data.
PING zookeeper (172.19.0.2) 56(84) bytes of data.
PING zookeeper (172.19.0.2) 56(84) bytes of data.
I am running on Apple M1 Chipset
What else can I check and do here?

Answer 1

Try using confluentinc's zookeeper image: confluentinc/cp-zookeeper:latest
I was in the exact same boat, also on the M1 chip and this worked for me.
These are the two services from my docker-compose for ref:
zoo:
image: confluentinc/cp-zookeeper:latest
restart: unless-stopped
ports:
- 2181:2181
environment:
ZOO_MY_ID: 1
ZOO_PORT: 2181
ZOO_SERVERS: server.1=zoo:2888:3888
ZOOKEEPER_CLIENT_PORT: 2181
kafka:
image: confluentinc/cp-kafka:latest
restart: always
ports:
- 9092:9092
environment:
KAFKA_ADVERTISED_LISTENERS: LISTENER_DOCKER_INTERNAL://kafka:19092,LISTENER_DOCKER_EXTERNAL://${DOCKER_HOST_IP:-127.0.0.1}:9092
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: LISTENER_DOCKER_INTERNAL:PLAINTEXT,LISTENER_DOCKER_EXTERNAL:PLAINTEXT
KAFKA_INTER_BROKER_LISTENER_NAME: LISTENER_DOCKER_INTERNAL
KAFKA_ZOOKEEPER_CONNECT: 'zoo:2181'
KAFKA_BROKER_ID: 1
KAFKA_LOG4J_LOGGERS: 'kafka.controller=INFO,kafka.producer.async.DefaultEventHandler=INFO,state.change.logger=INFO'
KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
depends_on:
- zoo
