Kafka containers with Docker Compose

Published July 18, 2023Last updated February 4, 20241 min read

Docker Compose facilitates spinning up containers for Kafka broker and Zookeeper without installing them locally. Zookeeper is used to track cluster state, membership, and leadership.

Prerequisites

  • Docker Compose installed

Configuration

The following configuration spins up Kafka and Zookeeper containers with the Kafka UI tool.

The Kafka broker address is http://localhost:29092, and Kafka UI is available at the http://localhost:8085 address.

# docker-compose.yml
