DEalog Kafka Development Cluster

This is a development cluster, do not use in production.

The origin docker-compose file is from the "QUARKUS - USING APACHE KAFKA WITH REACTIVE MESSAGING" Guide [1]

Requirements

• Docker
• Docker Compose

Development

Prerequisites

• Download the docker-compose.yaml or clone the repository and run docker-compose
• If not already there create the dealog_dev network: docker network create dealog_dev

docker-compose up [-d]

Available listeners

To be able to use the cluster locally as well as Docker there are two listeners available:

• localhost:9092 for local (external) access
• kafka:29092 for Docker (internal) access

Run commands

Use docker-compose exec kafka ls bin/ to see the top level scripts.

Manually produce messages

docker-compose exec kafka bin/kafka-console-producer.sh --broker-list kafka:29092 --topic messages

Kafka WebView

The Docker Compose setup comes bundled with the Kafka WebView

This is started and exposed on port 8081.

Open http://localhost:8081 in your web browser.

First you need to setup the cluster (kafka:29092). Next you need to create a view. Then you can either browse or stream the messages.

The initial username is admin@example.org, the default password is admin.
