Kubernetes-Based Edge Computing Framework

A modern JavaScript-based framework for managing edge computing workloads using Kubernetes. This framework enables efficient deployment, management, and monitoring of applications across distributed edge nodes.

Architecture

The framework consists of two main components:

1. Central Orchestrator: A Node.js-based service that manages edge nodes, workloads, and security.
2. Edge Agent: A lightweight Node.js application that runs on edge nodes and communicates with the central orchestrator.

Features

• Edge Node Management: Register, monitor, and manage edge nodes
• Workload Orchestration: Deploy and manage containerized applications on edge nodes
• Security: Secure communication between orchestrator and edge nodes
• Monitoring: Collect and visualize metrics from edge nodes
• Kubernetes Integration: Leverage Kubernetes for container orchestration at the edge

Prerequisites

• Node.js 18 or higher
• Docker
• Kubernetes cluster (or K3s for lightweight deployments)

Installation

Central Orchestrator

# Clone the repository
git clone https://github.com/yourusername/kubernetes-edge-framework.git
cd kubernetes-edge-framework

# Install dependencies
cd central-orchestrator
npm install

# Start the orchestrator
npm start

Edge Agent

# Navigate to edge-agent directory
cd edge-agent

# Install dependencies
npm install

# Start the agent
npm start

Deployment with Kubernetes

The framework includes deployment scripts for Kubernetes:

# Deploy the central orchestrator
cd deployment
./install-orchestrator.sh

# Deploy edge agents
./install-edge.sh
