secubox-app-dns-provider

Programmatic DNS record management via provider REST APIs. Part of the SecuBox ecosystem.

Overview

Manages DNS zones through OVH, Gandi, and Cloudflare APIs. Provides a CLI tool (dnsctl) for record CRUD, HAProxy vhost sync, DNS propagation verification, and ACME DNS-01 certificate issuance.

Architecture

dnsctl (CLI)
  ├── load_provider() → sources /usr/lib/secubox/dns/{provider}.sh
  ├── cmd_list/add/rm → delegates to dns_list/dns_add/dns_rm
  ├── cmd_sync → iterates HAProxy UCI vhosts → dns_add per domain
  ├── cmd_verify → nslookup against 1.1.1.1, 8.8.8.8, 9.9.9.9
  └── cmd_acme_dns01 → exports provider env vars → acme.sh --dns

Provider Adapters

Each adapter in /usr/lib/secubox/dns/ implements:

Function	Description
`dns_list(zone)`	List all records in zone
`dns_add(zone, type, subdomain, target, ttl)`	Create record
`dns_rm(zone, type, subdomain)`	Delete record
`dns_verify(fqdn)`	Check resolution
`dns_test_credentials()`	Validate API keys

Supported Providers

OVH — HMAC-SHA1 signed API v1 (app_key + app_secret + consumer_key)
Gandi — LiveDNS v5 with Bearer token
Cloudflare — API v4 with Bearer token + zone_id

UCI Configuration

/etc/config/dns-provider
  config dns_provider 'main'     → enabled, provider, zone
  config ovh 'ovh'               → endpoint, app_key, app_secret, consumer_key
  config gandi 'gandi'           → api_key
  config cloudflare 'cloudflare' → api_token, zone_id

CLI Usage

dnsctl status                          # Show config status
dnsctl test                            # Verify API credentials
dnsctl list                            # List zone records
dnsctl add A myservice 1.2.3.4        # Create A record
dnsctl add CNAME www mycdn.net        # Create CNAME
dnsctl rm A myservice                  # Remove record
dnsctl sync                            # Sync HAProxy vhosts to DNS
dnsctl verify myservice.example.com    # Check propagation
dnsctl acme-dns01 '*.example.com'      # Wildcard cert via DNS-01

Dependencies

curl — HTTP client for API calls
openssl-util — HMAC-SHA1 signing (OVH)
jsonfilter — JSON parsing (OpenWrt native)
acme.sh — Certificate issuance (optional, for DNS-01)
