Kafka DEV setup for unix systems

A small installation script to create a single-broker Kafka cluster with Web-UI. This is for development purposes only.

Setup

1. Copy repository and run install.sh script!

git clone https://github.com/noncommunicado/kafka-dev.git kafka-dev
cd ./kafka-dev
sudo chmod +x ./install.sh
./install.sh

Docker compose will run automatically.

2. If you have several network interfaces, please check docker-compose.yaml for correct IP setup in kafka broker environment.

Script will replace {{MY_IP}} with first net-interface IP automatically.

# replace with another IP or Host if need
- KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://{{MY_IP}}:9092

3. By default here, broker has persistent data in volume ./kafka, comment it in docker-compose.yaml file if you need.
4. Access kafka UI with http://{machine-ip-or-host:8080

Docker Compose file review

Note! Change network address if host machine locates in the same subnet.
