🚀 The "Single-Node Hero" Strategy

The Single-Node Hero is the first major milestone in your scaling journey. It bridges the gap between your laptop and a full multi-node managed cluster, providing a professional production environment on a budget (starting around $4-12/mo).

💡 The Core Concept​

Traditional Kubernetes deployments often require expensive Load Balancers (costing ~$15-30/mo) just to get traffic into your cluster. The Single-Node Hero strategy eliminates this cost by utilizing the server's own networking stack for ingress.

🛠 Technical Implementation​

1. HostPort Ingress (Direct Access)​

Instead of a LoadBalancer service, LaraKube CLI configures the Traefik Ingress Controller to use HostPorts on ports 80 and 443. This means Traefik listens directly on the VPS's public IP address, saving you the monthly load balancer fee while maintaining professional traffic management.

2. Automated Swap (Low-RAM Stability)​

Small VPS instances (like a 1GB or even 512MB droplet) can be unstable under heavy Kubernetes workloads. When you run larakube cloud:provision, LaraKube CLI automatically:

  • Detects the available memory.
  • Creates and enables a 1GB Swap file on the server.
  • Ensures your cluster remains stable even when running multiple Laravel services (Web, Horizon, Reverb) on minimal hardware.

3. Built-in ACME (Let'sEncrypt)​

SSL is non-negotiable for production. LaraKube CLI's Cloud Pilot automatically configures Traefik with the ACME (Let'sEncrypt) HTTP challenge. Once your domain is pointed to your VPS IP, LaraKube CLI handles the certificate provisioning and renewals automatically.

🏆 Why It Matters​

  • Cost Efficiency: Save ~$200-400/year by skipping cloud-provider load balancers.
  • Production Parity: Your application still runs on Kubernetes, ensuring that when you're ready to "graduate" to multi-node HA, your manifests are already proven and ready.
  • Simplicity: One command (larakube cloud:provision) transforms a fresh Linux box into a hardened, production-ready Kubernetes node.

🏁 Getting Started​

Ready to deploy? Ensure your domain is pointed to your VPS IP, then run:

larakube cloud:provision

Follow the prompts to secure your server, install K3s, and deploy the Single-Node Traefik stack.
