rabik/kafka-message-producer repository overview

⁠Kafka Message Producer

A lightweight, web-based Kafka message producer with a built-in UI. Connect to any Kafka broker and send messages in three modes — perfect for testing, debugging, and demos.

⁠Features

• Single message — send one message at a time
• Batch (count) — send up to 10,000 messages in one shot
• Interval — continuously send messages at a configurable interval
• Custom message structure — define topic, key, value (JSON or plain text), and headers
• Multi-platform — runs on linux/amd64 and linux/arm64 (Intel, AMD, Apple Silicon)

⁠Quick Start

docker run -p 8990:8990 rabik/kafka-message-producer

Open http://localhost:8990⁠ in your browser, enter your Kafka broker address, and start producing.

⁠Docker Compose (with Kafka)

If you need a full stack with Kafka included:

services:
  zookeeper:
    image: confluentinc/cp-zookeeper:7.6.0
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
    ports:
      - "2181:2181"

  kafka:
    image: confluentinc/cp-kafka:7.6.0
    depends_on:
      - zookeeper
    ports:
      - "9092:9092"
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1

  producer-ui:
    image: rabik/kafka-message-producer
    ports:
      - "8990:8990"
    depends_on:
      - kafka
