Hi Eno,
Great finding! You were right! I had to change KAFKA_ADVERTISED_LISTENERS
to be PLAINTEXT://$(docker-machine ip ):
to make it work from IDE. Step 2 (pointing to

in my stream app) was already done.
Later, I'll try using CLI as mentioned here https://github.com/
Ah, I see.

Hi Michael,
I was aware that the output should be written in a kafka topic not the
console.
To understand if streams can reach the kafka as Eno asked in earlier email

Hi Mina,
It might be that you need to set this property on the Kafka broker config file
(server.properties):
advertised.listeners=PLAINTEXT://your.host.name:9092
The problem might be this: within docker you run Kafka and Kafka’s address is
localhost:9092. Great. Then say you have another

Looks like that it does not connect to Kafka.
The WordCount demo example writes its output to Kafka only -- it *does
not* write any results to the console/STDOUT.

Hi,
I just checked streams-wordcount-output topic using below command
docker run \
--net=host \
--rm \
confluentinc/cp-kafka:3.2.0 \
kafka-console-consumer --bootstrap-server localhost:9092 \
--topic streams-wordcount-output \
--from-beginning \
I even tried
http://docs.confluent.io/3.2.0/streams/quickstart.html#goal-of-this-quickstart
and in docker-machine ran /usr/bin/kafka-run-class
org.apache.kafka.streams.examples.wordcount.WordCountDemo
Running
docker run --net=host --rm confluentinc/cp-kafka:3.2.0

Hi,
I forgot to add in my previous email 2 questions.
To setup my env, shall I use
https://raw.githubusercontent.com/confluentinc/cp-docker-images/master/examples/kafka-single-node/docker-compose.yml
instead or is there any other docker-compose.yml (version 2 or 3) which is
suggested to setup
And the port for kafka is 29092 and for zookeeper 32181.

Hi Eno,
Sorry! That is a typo!
I have a docker-machine with different containers (setup as directed @
http://docs.confluent.io/3.2.0/cp-docker-images/docs/quickstart.html)
docker ps --format "{{.Image}}: {{.Names}}"
confluentinc/cp-kafka-connect:3.2.0: kafka-connect
Hi there,
I noticed in your example that you are using localhost:9092 to produce but
localhost:29092 to consume? Or is that a typo? Is zookeeper, kafka, and the
Kafka Streams app all running within one docker container, or in different
containers?
I just tested the WordCountLambdaExample and
Any book, document and provides information on how to use kafka stream?

My env is setup using

I just tried using

Did you reset your application?
Each time you run you app and restart it, it will resume processing
where it left off.
Hi Matthias,
Thank you for the quick response, appreciate it!
I created the topics wordCount-input and wordCount-output. Pushed some data
to wordCount-input using
docker exec -it $(docker ps -f "name=kafka\\." --format "{{.Names}}")
/bin/kafka-console-producer --broker-list localhost:9092
Maybe you need to reset your application using the reset tool:
http://docs.confluent.io/current/streams/developer-guide.html#application-reset-tool
Also keep in mind, that KTables buffer internally, and thus, you might
only see data on commit.
Try to reduce commit interval or disable caching by
Hi,
This is the first time that am using Kafka Stream. I would like to read
from input topic and write to output topic. However, I do not see the word
count when I try to run below example. Looks like that it does not connect
to Kafka. I do not see any error though. I tried my localhost kafka as
17 matches
