To do this, execute the following command from your terminal. ~/demo/kafka-local docker exec -ti kafka-tools bash root@kafka-tools:/# If you see root@kafka-tools:/#, you’re in! Create a separate docker container 'kafka-setup' which is just required to get the kafka command-line tools. In that replace the startup command to execute some (good enough) wait operations and runs the /kafka/topic_creator.sh (with host:port-parameter of zookeeper and kafka) which is injected via volume. IFS= " ${KAFKA_CREATE_TOPICS_SEPARATOR-,} "; for topicToCreate in $KAFKA_CREATE_TOPICS; do: echo " creating topics: $topicToCreate " IFS= ': ' read-r -a topicConfig <<< " $topicToCreate " config= if [ -n " ${topicConfig[3]} "]; then: config= "--config=cleanup.policy= ${topicConfig[3]} " fi: COMMAND= " JMX_PORT='' ${KAFKA_HOME} /bin/kafka-topics.sh \\--create \\ 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” Syntax to create Kafka Topic Following is the syntax to create a topic : ./kafka-topics.sh --create --zookeeper --replication-factor --partitions --topic In order for Kafka to start working, we need to create a topic within it.

Topics will include Cloud Computing | Open Source | AWS | Azure | GCP | Serverless | DevOps | Big Data | ML | AI | Security | Kubernetes | AppDev | SaaS

Dockerfile for Apache Kafka. The image is available directly from Docker Hub Here is an example snippet from docker-compose.yml: environment: KAFKA_CREATE_TOPICS: “Topic1:1:3,Topic2:1:1:compact” Here, we can see Topic 1 is having 1 partition as well as 3 replicas // Print out the topics // You should see no topics listed $ docker exec -t kafka-docker_kafka_1 \ kafka-topics.sh \ --bootstrap-server :9092 \ --list // Create a topic t1 $ docker exec -t kafka-docker_kafka_1 \ kafka-topics.sh \ --bootstrap-server :9092 \ --create \ --topic t1 \ --partitions 3 \ --replication-factor 1 // Describe topic t1 $ docker exec -t kafka-docker_kafka_1 \ kafka-topics Once the Docker image for fast-data-dev is running you will be able to access theLandoop’s Kafka UI. This gives developers the ability to see in real-time what Kafka is doing, how it creates and manages topics. You can visually see configuration and topic data in the UI. Landoop’s Kafka UI: http://127.0.0.1:3030/ Working with Kafka via Command Line The Kafka Connect Datagen connector was installed automatically when you started Docker Compose in Step 1: Download and Start Confluent Platform Using Docker.

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.

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. kafka-topics--zookeeper localhost: 2181--create--topic test--partitions 3--replication-factor 1 We have to provide a topic name, a number of partitions in that topic, its replication factor along with the address of Kafka's zookeeper server. 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.

This tool is bundled inside Kafka installation, so let’s exec a bash terminal inside the Kafka container. docker exec -it $(docker ps -q --filter "label=com.docker.compose.service=kafka") /bin/bash I am trying to set up docker image for kafka topic.

we run multiple brokers. Kafka brokers have the messages for the topics.

of stuff though, so I wouldn't worry too much about that when suggesting topics. Create and set up test environments to reproduce and resolve customer issues.
