xk3s Fleet Topology & Cluster Manual
Comprehensive reference architecture, static network coordinates, mutual SSH key authentication matrix, and containerized workload topologies for the personal edge Kubernetes cluster.
1. 🗺️ Master Fleet Coordinates
The personal infrastructure consists of 6 primary nodes connected across local LAN, WireGuard cloud overlay, and Tailscale zero-trust meshes:
| Device | Hostname | User | LAN IP | WireGuard | Tailscale | Ingress / Role |
|---|---|---|---|---|---|---|
| MacBook Air | das-MacBook-Air.local | da | 192.168.4.••• | — | 100.71.•••.•• | Primary Workstation (M1, 16GB) |
| MacBook Pro | Doxs-MacBook-Pro.local | dx | 192.168.4.••• | — | 100.102.•••.•• | Secondary Workstation (i9, 32GB) |
| x1 (Master) | xrpi1 | x1 | 192.168.4.••• | 10.10.0.•• | 100.95.•••.•• | K3s Master, NVMe Storage, API (6443) |
| x2 (Worker) | xrpi2 | x2 | 192.168.4.••• | 10.10.0.•• | 100.71.•••.•• | K3s Edge Worker, HDMI Kiosk, VNC (5900) |
| AWS Hub (EC2) | ip-172-31-2-180 | ubuntu | — | 10.10.0.•• | — | Ingress Gateway (54.215.•••.••) |
| dphone | dphone | — | — | — | 100.64.•••.•• | Mobile iOS Zero-Trust Client |
2. 🔑 Remote Access & SSH Matrix
Passwordless ED25519 authentication is configured across all devices. Use these standard connection commands:
# Workstation Remote Access
ssh mbp # Connect to MacBook Pro (Tailscale)
ssh mbp-lan # Connect to MacBook Pro (LAN: 192.168.4.•••)
open vnc://dx@100.102.•••.•• # Screen Share VNC session
# Edge Cluster Node Access
ssh x1@100.95.•••.•• # Cluster Master x1 (Tailscale)
ssh x2@100.71.•••.•• # Edge Worker x2 (Tailscale)
# AWS Cloud Gateway
ssh ec2-pub # AWS EC2 Ingress Gateway (54.215.•••.••)
ssh mbp # Connect to MacBook Pro (Tailscale)
ssh mbp-lan # Connect to MacBook Pro (LAN: 192.168.4.•••)
open vnc://dx@100.102.•••.•• # Screen Share VNC session
# Edge Cluster Node Access
ssh x1@100.95.•••.•• # Cluster Master x1 (Tailscale)
ssh x2@100.71.•••.•• # Edge Worker x2 (Tailscale)
# AWS Cloud Gateway
ssh ec2-pub # AWS EC2 Ingress Gateway (54.215.•••.••)
3. ⚡ Dedicated K3s Kubernetes Cluster
The cluster runs lightweight Kubernetes (K3s) with dedicated control plane and edge worker nodes:

4. 🌐 Multi-Tier Mesh Overlay
The network utilizes a three-tier overlay model guaranteeing encrypted connectivity across all environments:
- Tier 1: Cloud-to-Edge Tunnel (WireGuard
10.10.0.0/24): Dedicated point-to-point encrypted link connecting AWS EC2 gateway to nodex1and nodex2. - Tier 2: Zero-Trust Remote Mesh (Tailscale
100.64.0.0/10): Direct peer-to-peer WireGuard mesh connecting MacBook Air, MacBook Pro, mobile clients, and edge nodes without open inbound firewall ports. - Tier 3: Local Area Network (LAN
192.168.4.0/24): Ultra low-latency physical link between on-premise hardware workstations and edge micro-servers.
