Kubernetes (k3s) for Shared Services

In this video I'll show you how to create a lightweight K3s Kubernetes server that acts as a shared‑services hub for my Proxmox environment. The cluster runs essential services such as a Docker registry, secret manager, SSO, and more. Allowing my apps, running on Proxmox, to consume resources over the network, without tying them directly into the Proxmox stack. 🔔 **Subscribe** for more hands‑on cloud & virtualization tutorials! What you’ll learn: - How a dedicated K3s cluster can provide centralized shared services for a Proxmox cluster - K3s installation and kube‑config setup on Ubuntu - Adding persistent storage with Longhorn for stateful workloads (databases, registries) - Internal load balancing using MetalLB (L2 mode) to expose services from k3s - Setting up an Ingress‑Nginx controller and DNS to give expose k3s services *To follow along, check out my GitHub page!
