RoundRobin-Go

RoundRobin-Go is a Go middleware implementing the round-robin algorithm for load balancing. It evenly distributes requests across multiple servers or resources in a circular order, enhancing system performance. Easy to integrate, it offers a simple solution for load distribution in Go applications.

Features

• Simple and efficient round-robin load balancing
• Concurrent request handling
• Easy configuration via included JSON and environment files
• Docker support for easy deployment

Getting Started

Prerequisites

• Go 1.22 or later
• Git

Clone the Repository

To get started with RoundRobin-Go, clone the repository to your local machine:

git clone https://github.com/CameronMcConnell/RoundRobin-Go.git
cd RoundRobin-Go

Configuration

The project includes two pre-configured files:

1. servers.json: Contains the list of backend servers for load balancing.
2. .env: Specifies the server address for the middleware.

You can modify these files to suit your needs:

Edit servers.json to add or remove backend servers:

[
  "http://backend1:8081",
  "http://backend2:8082",
  "http://backend3:8083"
]

Adjust the .env file to change the server address if needed:

SERVER_ADDRESS=:8080

Running the Application

Run the application:

go run main.go

The server will start on the address specified in the .env file.

Usage

Once the server is running, it will distribute incoming requests to the /roundrobin-go endpoint across the configured backend servers in a round-robin fashion.

Docker Support

To build and run RoundRobin-Go using Docker:

1. Build the Docker image:

docker build -t roundrobin-go .

2. Run the container:

docker run -p 8080:8080 roundrobin-go

Note: The servers.json and .env files are included in the Docker image during the build process.

Project Structure

• main.go: Entry point of the application
• lib/: Contains the core logic for the round-robin server
• servers.json: Configuration file for backend servers (included)
• .env: Environment file for server address configuration (included)
