Original: Self-Hosting Like a Pro, Part 2: Docker, K3s and Traefik v3 with Automatic HTTPS

Short summary

Part 2 of a self-hosting series covering Docker, K3s, and Traefik v3 installation on a 10€/month VPS. K3s provides full Kubernetes API compatibility in a ~512MB footprint, ideal for single-node multi-project hosting with resource isolation. The guide walks through DNS setup, Docker installation, K3s deployment with Traefik disabled, and Helm installation for subsequent Traefik v3 and cert-manager configuration.

  • •K3s chosen over full Kubernetes for ~512MB footprint on a single-node VPS
  • •Docker installed for local image building; K3s deployed with bundled Traefik disabled for custom Helm-managed Traefik v3
  • •Guide covers DNS setup, container runtime, K3s install, and Helm preparation for automatic HTTPS
