# Cloudflare
|
|
|
|
## Overview
|
|
|
|
DNS provider and reverse proxy layer for all `*.tophermayor.com` domains. Handles TLS certificate issuance via DNS challenge on grizzley and ubuntu Traefik instances.
|
|
|
|
## Key Facts
|
|
|
|
- **DNS Zone**: `tophermayor.com` managed at Cloudflare
|
|
- **Role**: Authoritative DNS for all homelab public-facing services
|
|
- **Wildcard cert source**: grizzley Traefik obtains `*.tophermayor.com` cert via Cloudflare DNS challenge
|
|
- **certsync**: TLS certs synced from grizzley NFS mount (`/mnt/truenas/traefik-certs/grizzley`) → ubuntu via NFS or direct sync
|
|
|
|
## Traefik Integration
|
|
|
|
Both Traefik instances use `certresolver=cloudflare`:
|
|
|
|
```yaml
|
|
# ubuntu Traefik dynamic config
|
|
tls:
|
|
certresolver: cloudflare
|
|
domains:
|
|
- main: toophermayor.com
|
|
sans:
|
|
- "*.tophermayor.com"
|
|
```
|
|
|
|
grizzley is the primary ACME source; ubuntu obtains certs from the shared NFS mount or via grizzley → ubuntu cert sync pipeline.
|
|
|
|
## DNS Records
|
|
|
|
| Record | Type | Target | Purpose |
|
|
|--------|------|--------|---------|
|
|
| `*.tophermayor.com` | A/CNAME | Traefik ingress | Wildcard for all services |
|
|
| `@.tophermayor.com` | A | Home IP | Bare domain |
|
|
| `traefik.tophermayor.com` | A | 192.168.50.84 | Grizzley edge ingress direct |
