KAFKA_CREATE_TOPICS — Create a test topic with 5 partitions and 2 replicas. volumes — For more details on the binding, see this article. Run this command: >> docker-compose up -d. If you want to add more Kafka brokers: >> docker-compose stop >> docker-compose scale kafka=3. You should be able to run docker ps and see the 2 containers:

Improve this answer. If we want to have Kafka-docker automatically create topics in Kafka during creation, a KAFKA_CREATE_TOPICS environment variable can be added in docker-compose.yml. Here is an example snippet from docker-compose.yml: environment: KAFKA_CREATE_TOPICS: “Topic1:1:3,Topic2:1:1:compact” IP: 192.168.99.100 : Docker toolbox default IP ## CREATE TOPIC - NUMBERS docker exec kafka-1 kafka-topics --bootstrap-server 192.168.99.100:9092 --create --topic numbers --partitions 3 In order for Kafka to start working, we need to create a topic within it. The producer clients can then publish streams of data (messages) to the said topic and consumers can read the said datastream, if they are subscribed to that particular topic. To do this we need to start a interactive terminal with the Kafka container. In the Topic name field, specify pageviews and click Create with defaults.

So I wrote a Dockerfile, with ENTRYPOINT executing a shell script for the above sequence: kafka-topics --zookeeper localhost:2181 --create --topic new-topic --partitions 1 --replication-factor 1 > Created topic "new-topic". If you don't have the Kafka command line tools installed, you can run a command using Docker as well: Kafka can create the topics automatically when you first produce to the topic; that’s usually not the best choice for production, however, quite convenient in dev. In many situations, topic 2018-05-20 · In this short article, I will show you a simple way to run Kafka locally with Docker. In order to run Kafka, you need a Zookeeper instance and Kafka instance. You also need these two instances to be able to talk to each other.

A normal start-up sequence for a Kafka server is like this: A: start Zookeeper server B: start Broker server C: create topic. Item A and B are long running process. And C need to wait for B to come up and running.

Kafka Training: Using Kafka from the command line starts up ZooKeeper, and Kafka and then uses Kafka command line tools to create a topic, produce some messages and consume them.

It was not a breeze setup and had few hiccups on the way. 2015-09-30 · In docker-compose-single-broker.yml, edit the KAFKA_ADVERTISED_HOST_NAME with the IP address you copied above and the KAFKA_CREATE_TOPICS with the name of the default topic you would like created. The 1:1 refers to the number of partition and the replication factor for your partition.

The text was updated successfully, but these errors were encountered:

Container run command to create topic Use the container command docker run --net=host --rm. In the following example, the zookeeper is running on port 22181, please use the respective topic name, port. Problem: Cannot create topics from docker-compose. I need to create kafka topics before I run a system under test. Planning to use it as a part of the pipeline, hence using UI is not an option. Note: it takes ~15 seconds for kafka to be ready so I would need to put a sleep for 15 seconds prior to adding the topics.
