2019-05-23 · $ docker exec broker-tutorial kafka-topics --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 1 --topic blog-dummy Created topic "blog-dummy". So far, so good. Note that we also to pass in the --zookeeper argument to tell the command where our Zookeeper Instance is 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.

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. 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".

Be patient. You could see a lot of activities in the console log. When the logs are slowing down, the app could have started.

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. Possible solution:

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.

Run a Kafka producer and consumer To publish and collect your first message, follow these instructions: Export the authentication configuration:

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: Step 1: Create a overlay network: kafka-net; node3 > docker network create --driver overlay kafka-net. Step 2: Create a zookeeper service 2021-03-07 · INFO: This guide focus is not Kafka, therefore the following steps are straightforward. If you need more details about the upcoming commands please refer to this post: Bootstrapping Kafka and managing topics in 2 minutes.

In this quick start, you create Apache Kafka® topics, use Kafka Connect to generate mock data to those topics, and create ksqlDB streaming queries on those topics. Creating A Topic. Now that we have a Kafka cluster running, let's send some messages! To do this, we must first create a topic.
