🌟 My Kubernetes Lab Setup 🌟

Welcome to my Kubernetes lab setup! This document provides a comprehensive overview of the architecture and technologies I've implemented.

🖥️ Clusters Overview

🌐 Rancher Local Cluster

• ☁️ Hosting: Cloud-hosted

🌐 Rancher Imported Tenant (Cloud)

• 🖥️ Node Configuration: 2 nodes (8GB RAM, 4 CPU each)
• 🐳 Kubernetes Distribution: K3s
• 🛠️ Operating System: Ubuntu 22.04
• ☁️ Hosting: Cloud-hosted

🏠 Rancher Imported Tenant (Home)

• 🖥️ Node Configuration:
  • 1 node (8GB RAM, 4 CPU) - Laptop
  • 1 node (8GB RAM, 4 CPU) - Raspberry Pi 5
• 🐳 Kubernetes Distribution: K3s
• 🛠️ Operating System: Ubuntu 23.10

🗺️ Architecture Diagram

🔍 Diagram Summary

• The architecture diagram illustrates the following components and their interactions:

• 👤 User Requests: Initiated by the user and forwarded by the Nginx Reverse Proxy.

• 🔀 Nginx Reverse Proxy: Directs user requests to one of the three clusters (Cluster 1, Cluster 2, Cluster 3).

• 🌐 Clusters:

  • Cluster 1:
    • Deployed services include Vault.
    • Node Exporter collects and forwards metrics to Prometheus 1.
  • Cluster 2:
    • Deployed services include NeuVector and Grafana.
    • Node Exporter collects and forwards metrics to Prometheus 2.
  • Cluster 3:
    • Deployed services include ArgoCD.
    • Node Exporter collects and forwards metrics to Prometheus 3.

• 📊 Prometheus Instances: Each cluster has its own Prometheus instance (Prometheus 1, Prometheus 2, Prometheus 3) that scrapes and collects metrics.

• 🔗 Thanos: Aggregates metrics from all Prometheus instances and serves as a datasource for Grafana.

• 📈 Grafana: Visualizes metrics collected by Prometheus and Thanos.

🛠️ Tech Stack

• 🚀 Continuous Delivery: ArgoCD
• 🌍 Ingress Controller: Traefik
• 🔀 Reverse Proxy / Load Balancer: Nginx
• 📊 Monitoring: Prometheus, Grafana, Thanos
• 📜 Logging: Loki (In progress)
• 🔒 Security: NeuVector
