# Golang Kafka Docker Microservices Simple Example
This repository demonstrates a simple microservices architecture using Kafka, Golang, and Docker. The primary goal is to illustrate a basic setup necessary for inter-service communication through Kafka messaging queue.
## Overview
In this example:
- A client sends an HTTP request to the first microservice (API Gateway) using a tool like Postman.
- The API Gateway forwards the request to Kafka, which is then picked up by the second microservice.
- The second microservice processes the request and sends the response back to Kafka.
- The API Gateway retrieves the response from Kafka and sends it back to the client.
> Note: It's essential to have a mechanism for correlating requests and responses to ensure that each response is sent back to the correct client, especially when handling multiple concurrent requests.
## Getting Started
### Prerequisites
- Docker and Docker-Compose
### Running the Project
1. Clone the repository to your local machine:
```sh
git clone [email protected]:nikkhvat/kafka-golang-example.git
cd kafka-golang-example
```
2. Build the Docker containers:
```sh
docker-compose build
```
3. Start the services:
```sh
docker-compose up
```
Now, the API Gateway service is running on http://localhost:8080, and you can send an HTTP GET request to /ping endpoint to trigger the communication between the microservices.
