Types

type Capability

type Capability uint32

Capability is a bitmasked set of "features" that a provider supports. Only use constants from this package.

const (

	// CanAutoDNSSEC indicates that the provider can automatically handle DNSSEC,
	// so folks can ask for that.
	CanAutoDNSSEC Capability = iota

	// CanGetZones indicates the provider supports the get-zones subcommand.
	CanGetZones

	// CanUseAKAMAICDN indicates the provider support the specific AKAMAICDN records that only the Akamai EdgeDns provider supports
	CanUseAKAMAICDN

	// CanUseAlias indicates the provider support ALIAS records (or flattened CNAMES). Up to the provider to translate them to the appropriate record type.
	CanUseAlias

	// CanUseAzureAlias indicates the provider support the specific Azure_ALIAS records that only the Azure provider supports
	CanUseAzureAlias

	// CanUseCAA indicates the provider can handle CAA records
	CanUseCAA

	// CanUseDS indicates that the provider can handle DS record types. This
	// implies CanUseDSForChildren without specifying the latter explicitly.
	CanUseDS

	// CanUseDSForChildren indicates the provider can handle DS record types, but
	// only for children records, not at the root of the zone.
	CanUseDSForChildren

	// CanUseLOC indicates whether service provider handles LOC records
	CanUseLOC

	// CanUseNAPTR indicates the provider can handle NAPTR records
	CanUseNAPTR

	// CanUsePTR indicates the provider can handle PTR records
	CanUsePTR

	// CanUseRoute53Alias indicates the provider support the specific R53_ALIAS records that only the Route53 provider supports
	CanUseRoute53Alias

	// CanUseSOA indicates the provider supports full management of a zone's SOA record
	CanUseSOA

	// CanUseSRV indicates the provider can handle SRV records
	CanUseSRV

	// CanUseSSHFP indicates the provider can handle SSHFP records
	CanUseSSHFP

	// CanUseTLSA indicates the provider can handle TLSA records
	CanUseTLSA

	// CantUseNOPURGE indicates NO_PURGE is broken for this provider. To make it
	// work would require complex emulation of an incremental update mechanism,
	// so it is easier to simply mark this feature as not working for this
	// provider.
	CantUseNOPURGE

	// DocCreateDomains means provider can add domains with the `dnscontrol create-domains` command
	DocCreateDomains

	// DocDualHost means provider allows full management of apex NS records, so we can safely dual-host with anothe provider
	DocDualHost

	// DocOfficiallySupported means it is actively used and maintained by stack exchange
	DocOfficiallySupported
)

func (Capability) String

func (i Capability) String() string

type CustomRType

type CustomRType struct {
	Name     string
	Provider string
	RealType string
}

CustomRType stores an rtype that is only valid for this DSP.

func GetCustomRecordType

func GetCustomRecordType(rType string) *CustomRType

GetCustomRecordType returns a registered custom record type, or nil if none

type DNSServiceProvider

type DNSServiceProvider interface {
	models.DNSProvider
}

DNSServiceProvider is able to generate a set of corrections that need to be made to correct records for a domain. Implement this only if the provider is a DNS Service Provider (can update records in a DNS zone).

func CreateDNSProvider

func CreateDNSProvider(providerTypeName string, config map[string]string, meta json.RawMessage) (DNSServiceProvider, error)

CreateDNSProvider initializes a dns provider instance from given credentials.

type DocumentationNote

type DocumentationNote struct {
	HasFeature    bool
	Unimplemented bool
	Comment       string
	Link          string
}

DocumentationNote is a way for providers to give more detail about what features they support.

func Can

func Can(comments ...string) *DocumentationNote

Can is a small helper for concisely creating Documentation Notes comments are variadic for easy ommission. First is comment, second is link, the rest are ignored.

func Cannot

func Cannot(comments ...string) *DocumentationNote

Cannot is a small helper for concisely creating Documentation Notes comments are variadic for easy ommission. First is comment, second is link, the rest are ignored.

func Unimplemented

func Unimplemented(comments ...string) *DocumentationNote

Unimplemented is a small helper for concisely creating Documentation Notes comments are variadic for easy ommission. First is comment, second is link, the rest are ignored.

type DocumentationNotes

type DocumentationNotes map[Capability]*DocumentationNote

DocumentationNotes is a full list of notes for a single provider

type DspFuncs

type DspFuncs struct {
	Initializer   DspInitializer
	RecordAuditor RecordAuditor
}

DspFuncs lists functions registered with a provider.

type DspInitializer

type DspInitializer func(map[string]string, json.RawMessage) (DNSServiceProvider, error)

DspInitializer is a function to create a DNS service provider. Function will be passed the unprocessed json payload from the configuration file for the given provider.

type None

type None struct{}

None is a basic provider type that does absolutely nothing. Can be useful as a placeholder for third parties or unimplemented providers.

func (None) GetDomainCorrections

func (n None) GetDomainCorrections(dc *models.DomainConfig) ([]*models.Correction, error)

GetDomainCorrections returns corrections to update a domain.

func (None) GetNameservers

func (n None) GetNameservers(string) ([]*models.Nameserver, error)

func (None) GetRegistrarCorrections

func (n None) GetRegistrarCorrections(dc *models.DomainConfig) ([]*models.Correction, error)

GetRegistrarCorrections returns corrections to update registrars.

func (None) GetZoneRecords

func (n None) GetZoneRecords(domain string) (models.Records, error)

GetZoneRecords gets the records of a zone and returns them in RecordConfig format.

func (None) GetZoneRecordsCorrections

func (n None) GetZoneRecordsCorrections(dc *models.DomainConfig, records models.Records) ([]*models.Correction, error)

GetZoneRecordsCorrections gets the records of a zone and returns them in RecordConfig format.

type ProviderMetadata

type ProviderMetadata interface{}

ProviderMetadata is a common interface for DocumentationNotes and Capability to be used interchangeably

type RecordAuditor

type RecordAuditor func([]*models.RecordConfig) []error

RecordAuditor is a function that verifies that all the records are supportable by this provider. It returns a list of errors detailing records that this provider can not support.

type Registrar

type Registrar interface {
	models.Registrar
}

Registrar is an interface for a domain registrar. It can return a list of needed corrections to be applied in the future. Implement this only if the provider is a "registrar" (i.e. can update the NS records of the parent to a domain).

func CreateRegistrar

func CreateRegistrar(rType string, config map[string]string) (Registrar, error)

CreateRegistrar initializes a registrar instance from given credentials.

type RegistrarInitializer

type RegistrarInitializer func(map[string]string) (Registrar, error)

RegistrarInitializer is a function to create a registrar. Function will be passed the unprocessed json payload from the configuration file for the given provider.

type ZoneCreator

type ZoneCreator interface {
	EnsureZoneExists(domain string) error
}

ZoneCreator should be implemented by providers that have the ability to create zones (used for automatically creating zones if they don't exist)

type ZoneLister

type ZoneLister interface {
	ListZones() ([]string, error)
}

ZoneLister should be implemented by providers that have the ability to list the zones they manage. This facilitates using the "get-zones" command for "all" zones.
