This project provides a comprehensive framework for deploying and managing production-ready Kubernetes clusters on bare-metal and virtual machines. It leverages Ansible automation to create resilient, fully automated K3s environments with minimal configuration effort.

The automation is built around a collection of specialized Ansible roles that handle every aspect of the cluster lifecycle, from initial deployment and configuration to ongoing maintenance and upgrades.

• Core Infrastructure: Fully automated K3s installation on Ubuntu LTS with embedded etcd for high availability and HAProxy with Keepalived for Kubernetes API server load balancing
• Advanced Networking: Cilium CNI for eBPF-based networking, replacing kube-proxy with optimized service load balancing and Gateway API for ingress
• DNS Management: CoreDNS for internal cluster DNS resolution and ExternalDNS for automatic external DNS record synchronization
• Package Management: Helm for simplified application deployment and management
• Security: TLS certificate management via cert-manager with automatic renewal and integration with external DNS providers
• Storage: Distributed block storage with Longhorn providing volume replication and backup capabilities
• Observability: Complete monitoring stack with Metrics Server for core resource metrics, VictoriaMetrics for advanced metrics collection, AlertManager for alert handling and routing, VictoriaLogs for centralized logging, and Grafana for visualization
• GitOps: ArgoCD for declarative application deployment following GitOps principles
• Maintenance: Coordinated node updates with Kured for minimizing disruption during system maintenance

A public session provides a comprehensive analysis of the cluster's architecture, technology choices, and operational characteristics, demonstrating production-grade SRE practices.
