This repository contains the complete setup for deploying a highly available, scalable, and observable Moodle LMS using Kubernetes (MicroK8s), Docker, and a monitoring stack built with Prometheus and Grafana.
- Deploy Moodle in a Kubernetes cluster with PHP + Nginx
- Use PostgreSQL as the persistent backend database
- Ensure data durability and service discovery
- Monitor application and node-level metrics using Prometheus + Grafana

The project is organized around modular Kubernetes deployments, with each service or technology housed in its own folder and, where needed, its own Git branch.

- Prometheus scrapes metrics from:
- Node Exporter (hardware metrics)
- Kubernetes pods
- Grafana uses Prometheus as a data source and provides dashboards to visualize:
- Pod CPU/memory
- Node health
- System load under user traffic
Simulated concurrent users were used to validate:
- Pod stability
- Resource monitoring
- Cluster resilience
- Kubernetes: deployments, volumes, services, manifests
- Docker: multi-layer images with PHP and Nginx
- Prometheus + Grafana configuration
- Infrastructure as Code (IaC)
- Collaborative DevOps using Git and modular branches
Each major component has its own branch in this repository with a dedicated README.md describing setup and usage in detail:
