Network Diagram Description

Components:

Physical Machine 1:
- Hosts VM 1 (Master Node) and VM 2 (Worker Node).
- Contains an NFS Server providing storage.
Physical Machine 2:
- Hosts VM 3 (Worker Node).
Network:
- All VMs are connected via a bridged network on the same subnet (e.g., 192.168.1.0/24).
- Communication occurs over IPv4 (IPv6 disabled).
External Access:
- A local client (e.g., your laptop) accesses applications via Traefik ingress on VM 1.

Connections:

VM 1 (Master):
- IP: 192.168.1.100 (example).
- Runs k3s server, Traefik ingress, and manages the cluster.
- Connects to VM 2 and VM 3 for cluster operations.
- Mounts NFS share from Physical Machine 1.
VM 2 (Worker):
- IP: 192.168.1.101.
- Runs k3s agent, hosts application pods.
- Mounts NFS share from Physical Machine 1.
VM 3 (Worker):
- IP: 192.168.1.102.
- Runs k3s agent, hosts application pods.
- Mounts NFS share from Physical Machine 1 over the network.
NFS Server (Physical Machine 1):
- IP: 192.168.1.10.
- Exports /path/to/share to the subnet.
Local Client:
- Accesses apps via http://.mylab.local resolved to VM 1’s IP.

Explanation of the ASCII Diagram:

Physical Machine 1 contains VM 1, VM 2, and the NFS server.
Physical Machine 2 contains VM 3.
All VMs connect to the Local Network (bridged, same subnet).
The NFS Server on Physical Machine 1 provides storage to all VMs.
The Local Client connects to VM 1 (master) to access applications via Traefik ingress.

How to Generate an Image

Since you requested a diagram and I can’t generate it directly:

Option 1: Would you like me to confirm with you to generate an image using an external tool after refining this description? I’d need your confirmation to proceed with that step.
Option 2: Copy the ASCII or description into a tool like draw.io or Mermaid Live Editor (using Mermaid syntax below) to render it visually.

Mermaid Syntax Example (for Tools Supporting Mermaid):

mermaid

graph TD A[Physical Machine 1] --> B[VM 1 Master 192.168.1.100 k3s Server Traefik] A --> C[VM 2 Worker 192.168.1.101 k3s Agent] A --> D[NFS Server 192.168.1.10 /path/to/share] E[Physical Machine 2] --> F[VM 3 Worker 192.168.1.102 k3s Agent] B --> G[Local Network 192.168.1.0/24] C --> G F --> G B --> D C --> D F --> D H[Local Client] --> G

Paste this into Mermaid Live Editor to see a basic flowchart.
