## Network
|
|
|
|
- **Mesh**: Tailscale (all nodes)
|
|
- **DNS**: os.scoble.me → n97-1 (Tailscale IP), SSL via Let's Encrypt + Cloudflare DNS
|
|
- **K8s API**: Tailscale-only, no public exposure

## Quickstart
|
|
|
|
```bash
|
|
# Build and deploy a node
|
|
nixos-rebuild switch --flake .#n97-1 --target-host root@100.x.x.x
|
|
|
|
# Access cluster
|
|
kubectl --kubeconfig /etc/rancher/k3s/k3s.yaml get nodes
|
|
|
|
# Deploy app
|
|
kubectl apply -k apps/forgejo/
|
|
```
