# Cloudflare DNS

Manage DNS records via Cloudflare API using the bundled `cf-dns.sh` script.

## Setup

Store credentials in environment or pass via flags:

```bash
export CF_API_TOKEN="your-api-token"
export CF_ZONE_ID="your-zone-id"       # optional, can auto-detect from domain
```

Get API token: Cloudflare Dashboard → My Profile → API Tokens → Create Token → "Edit zone DNS" template.

Get Zone ID: Cloudflare Dashboard → select domain → Overview → right sidebar "Zone ID".

## Usage

The script is at `scripts/cf-dns.sh`. All commands:

```bash
# List zones (find zone ID)
cf-dns.sh zones

# List all records for a zone
cf-dns.sh list <zone_id>
cf-dns.sh list --domain example.com

# Get specific record
cf-dns.sh get <zone_id> <record_id>

# Create record
cf-dns.sh create <zone_id> --type A --name www --content 1.2.3.4 [--ttl 300] [--proxied]
cf-dns.sh create <zone_id> --type CNAME --name blog --content example.com
cf-dns.sh create <zone_id> --type TXT --name @ --content "v=spf1 ..."
cf-dns.sh create <zone_id> --type MX --name @ --content mail.example.com --priority 10

# Update record
cf-dns.sh update <zone_id> <record_id> --content 5.6.7.8 [--ttl 600] [--proxied]

# Delete record
cf-dns.sh delete <zone_id> <record_id>

# DDNS: update A record to current public IP
cf-dns.sh ddns <zone_id> --name home
cf-dns.sh ddns --domain example.com --name home
```

## Common Patterns

**Add subdomain pointing to IP:**
```bash
cf-dns.sh create <zone_id> --type A --name subdomain --content 203.0.113.50 --proxied
```

**Set up email (MX + SPF):**
```bash
cf-dns.sh create <zone_id> --type MX --name @ --content mail.example.com --priority 10
cf-dns.sh create <zone_id> --type TXT --name @ --content "v=spf1 include:_spf.google.com ~all"
```

**Dynamic DNS for home server:**
```bash
# Run periodically via cron
cf-dns.sh ddns --domain example.com --name home
```

## Notes

- `--proxied` enables Cloudflare proxy (orange cloud) — hides origin IP, adds CDN
- TTL in seconds; use 1 for "Auto" when proxied
- `@` means root domain
- Script outputs JSON; pipe to `jq` for parsing
