model for a new provider

[Hamish Moffatt]

Hi Tom and all,

I was starting to implement support for a new provider with a fairly
sane looking HTTP API, which would be a good implementation to start from?

https://api.binarylane.com.au/reference/#tag/NameserverNotes


Thanks

Hamish

That's an excellent question!

Thinking out loud: I need to write a template to copy for new providers that demonstrates the best practices for which functions go in which filesnames, etc.  This might be a good opportunity to create a standard and migrate all existing providers to comply with the standard.

In the meantime, dnscontrol/providers/porkbun has a good layout.  Loopia does too, but it uses diff.NewCompat() which is old.  Do not copy the format of cloudflare... that was written long before we knew what we were doing (I'm mocking myself here).

Best,

Tom

Well, that was easy! From Porkbun I was able to get my new provider going for some basic functions in a few hours. I haven't tried the unit tests yet.

I'm a bit stuck on handling of the nameservers though. My provider does not include the apex NS records in the record list, nor can they be modified. I haven't declared any nameservers in my dnsconfig.js. When I run dnscontrol, I get:

INFO#1: Skipping registrar "none": No nameservers declared for domain "my-test-zone.dev". Add {no_ns:'true'} to force

var REG_NONE = NewRegistrar("none");    // No registrar.
var DNS_BINARYLANE = NewDnsProvider("binarylane");

D("my-test-zone.dev", REG_NONE, DnsProvider(DNS_BINARYLANE),
    DefaultTTL(3600),
    A("@", "1.1.1.1"),
    A("wwww", "1.1.1.2"),
    A("wwww2", "1.1.1.1")
);

I tried injecting NS records into the records list in GetZoneRecords(), but then dnscontrol saw those as needing to be deleted.

I don't declare my nameservers when using the Cloudflare provider and it doesn't warn about this there, so I don't know what's different. Any hints?

Thanks,

Hamish

Good to hear!

Is GetNameservers() defined?

(Doing this from memory...)   The GetNameservers() returns the parent nameservers.  That info comes from the registrar, not the NS records in the domain.  The two should match, and if they don't DNSControl will try to update the zone.

I tried injecting NS records into the records list in GetZoneRecords(), but then dnscontrol saw those as needing to be deleted.

Sounds like GetNameservers() is returning an empty list and DNSControl is, therefore, trying to  update the zone to match (i.e. delete the NS records).

 

I don't declare my nameservers when using the Cloudflare provider and it doesn't warn about this there, so I don't know what's different. Any hints?

With Cloudflare, GetNameservers() is defined, thus everything is automatic.  The NAMESERVER() commands are only needed when GetNameservers() isn't implemented.

Hope that helps!

Thanks, there was a logic error in GetNameservers() resulting in it not returning the list. It's working now.

Unfortunately I think this project is a non-starter as the provider seems to have a bunch of restrictions or bugs. I can't edit the TTL of anything, and I can't have an MX record with a label part of "foo.bar" (though an A record allows it), for example.

Yeah, that sounds pretty limiting.
