dvcrn Cloudflare DNS
Manage DNS records via Cloudflare API using the bundled cf-dns.sh script.
Setup
Store credentials in environment or pass via flags:
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:
# 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:
cf-dns.sh create <zone_id> --type A --name subdomain --content 203.0.113.50 --proxied
Set up email (MX + SPF):
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:
# Run periodically via cron
cf-dns.sh ddns --domain example.com --name home
Notes
--proxiedenables 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
