🎯 Project Overview

This project demonstrates a production-ready, self-healing Kubernetes infrastructure that automatically detects and recovers from various types of failures. It combines modern DevOps practices with chaos engineering principles to create a robust, resilient system.

🚀 What Makes This Special

This infrastructure automatically heals itself! When something breaks, it detects the issue and fixes it without human intervention. Perfect for production environments that need 99.9% uptime.

  • Self-Healing

    Automatic detection and recovery from node failures, pod crashes, and service disruptions in under 30 seconds.

🎬 Live Demo

Try It Yourself!

Want to see self-healing in action? Follow our quick start guide to deploy the infrastructure and break some pods - watch them heal automatically!

  • Quick Demo

    # Break a pod and watch it heal
kubectl delete pod <pod-name>
# ✅ Pod automatically recreated in 10s

  • Watch Recovery

    # Monitor the healing process
kubectl get pods --watch
# ✅ Real-time recovery monitoring

  • Run Chaos Test

    # Trigger chaos experiment
kubectl apply -f chaos-experiments.yaml
# ✅ System recovers automatically

  • Check Metrics

    # View recovery metrics
curl localhost:9090/metrics
# ✅ See healing statistics

🚀 Quick Start

Prerequisites

Before You Begin

Make sure you have these tools installed and configured properly.

  • Kubernetes

    Local cluster (Minikube, kind) or cloud provider (GKE, EKS, AKS)

  • kubectl

    Kubernetes command-line tool configured for your cluster

  • Terraform

    For infrastructure provisioning and management

  • Python 3.8+

    Required for the self-healing controller

Installation

# Clone the repository
git clone https://github.com/justrunme/self-healing-infrastructure-chaos-engineering.git
