SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reduces the complexity of building and operating small, single-node Kubernetes environments by providing a repeatable K3s setup with Traefik ingress, cert-manager TLS, and structured Kustomize overlays.

Core Features & Use Cases

  • K3s installation on a single-node cluster with Traefik default ingress
  • TLS setup using cert-manager and Let's Encrypt
  • Kustomize base + overlays for dev/stage/prod
  • Resource budgeting guidance for constrained hardware
  • IngressRoute configuration examples

Quick Start

Install K3s on your VPS and apply the Traefik, cert-manager, and Kustomize overlays to bootstrap a secure single-node cluster.

Frequently Asked Questions about kubernetes-k3s

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up a lightweight Kubernetes cluster on a single-node VPS?▼

Setting up K3s on a single-node VPS involves installing the K3s server, configuring the default Traefik ingress, and applying Kustomize overlays to bootstrap a reproducible, lightweight Kubernetes environment.

How do I configure TLS with cert-manager and Let's Encrypt in K3s?▼

Configuring TLS in K3s uses cert-manager integrated with Let's Encrypt to automate certificate provisioning, securing ingress routes for your single-node Kubernetes deployments.

Can I use Kustomize overlays for dev, stage, and prod environments in K3s?▼

Yes, you can use Kustomize base and overlays to manage dev, stage, and prod environments in K3s, enabling reproducible deployments across different environment-specific configurations.

What is the best way to manage resource budgeting on a low-RAM VPS running K3s?▼

The best way to manage resources on a low-RAM VPS running K3s is following resource budgeting guidance provided during the K3s setup, ensuring your single-node cluster operates smoothly on constrained hardware.

Does K3s work with Traefik for ingress route configuration?▼

Yes, K3s works with Traefik as the default ingress controller, providing IngressRoute configuration examples to establish secure and scalable ingress for your applications.

When should I not use K3s for my Kubernetes deployments?▼

You should avoid using K3s if your deployment requires multi-node clustering or exceeds the resource constraints of a single-node VPS, as this setup is optimized for lightweight, single-node environments.
