# DNS & Traefik Configuration - youtube.nuc.lan and business.nuc.lan

**Date:** 2026-02-12
**Context:** Added two new DNS entries on OpenWrt router and corresponding Traefik routes for youtube and business services.

## Changes Made

### 1. OpenWrt Router DNS Entries

Added two new domain entries via UCI:

```bash
uci add dhcp domain
uci set dhcp.@domain[-1].name="youtube.nuc.lan"
uci set dhcp.@domain[-1].ip="192.168.1.3"

uci add dhcp domain
uci set dhcp.@domain[-1].name="business.nuc.lan"
uci set dhcp.@domain[-1].ip="192.168.1.3"

uci commit dhcp
/etc/init.d/dnsmasq restart
```

**Verification:**
```bash
ssh -i ~/.ssh/id_ed25519_nuc root@192.168.1.1 'uci show dhcp | grep -E "youtube|business"'
# Output:
# dhcp.@domain[26].name='youtube.nuc.lan'
# dhcp.@domain[27].name='business.nuc.lan'
```

### 2. Traefik Routes Added

Updated `/traefik/dynamic/nuc-services.yaml` on coolify-proxy with two new routers and services:

**Router entries:**
```yaml
youtube:
  rule: Host(`youtube.nuc.lan`)
  entryPoints:
    - http
  service: youtube

business:
  rule: Host(`business.nuc.lan`)
  entryPoints:
    - http
  service: business
```

**Service entries:**
```yaml
youtube:
  loadBalancer:
    servers:
      - url: http://host.docker.internal:7107

business:
  loadBalancer:
    servers:
      - url: http://host.docker.internal:7108
```

## Verification Results

- **DNS Entry Check:** Both entries exist in router config ✓
- **Traefik Route Test (youtube):** Bad Gateway (502) - expected, no service running yet ✓
- **Traefik Route Test (business):** Bad Gateway (502) - expected, no service running yet ✓

## Access

Once services are deployed on ports 7107 and 7108:

- `http://youtube.nuc.lan` → `http://host.docker.internal:7107`
- `http://business.nuc.lan` → `http://host.docker.internal:7108`

Both work from LAN and Tailscale (via split DNS to router).
