func (*AWSSDRegistry) ApplyChanges

func (sdr *AWSSDRegistry) ApplyChanges(ctx context.Context, changes *plan.Changes) error

ApplyChanges filters out records not owned the External-DNS, additionally it adds the required label inserted in the AWS SD instance as a CreateID field

func (*AWSSDRegistry) Records

Records calls AWS SD API and expects AWS SD provider to provider Owner/Resource information as a serialized value in the AWSSDDescriptionLabel value in the Labels map

type NoopRegistry

type NoopRegistry struct {
	// contains filtered or unexported fields
}

func NewNoopRegistry

func NewNoopRegistry(provider provider.Provider) (*NoopRegistry, error)

NewNoopRegistry returns new NoopRegistry object

func (*NoopRegistry) ApplyChanges

func (im *NoopRegistry) ApplyChanges(ctx context.Context, changes *plan.Changes) error

ApplyChanges propagates changes to the dns provider

func (*NoopRegistry) Records

func (im *NoopRegistry) Records() ([]*endpoint.Endpoint, error)

Records returns the current records from the dns provider

type Registry

type Registry interface {
	Records() ([]*endpoint.Endpoint, error)
	ApplyChanges(ctx context.Context, changes *plan.Changes) error
}

type TXTRegistry

type TXTRegistry struct {
	// contains filtered or unexported fields
}

func NewTXTRegistry

func NewTXTRegistry(provider provider.Provider, txtPrefix, ownerID string, cacheInterval time.Duration) (*TXTRegistry, error)

NewTXTRegistry returns new TXTRegistry object

func (*TXTRegistry) ApplyChanges

func (im *TXTRegistry) ApplyChanges(ctx context.Context, changes *plan.Changes) error

ApplyChanges updates dns provider with the changes for each created/deleted record it will also take into account TXT records for creation/deletion

func (*TXTRegistry) Records

func (im *TXTRegistry) Records() ([]*endpoint.Endpoint, error)

Records returns the current records from the registry excluding TXT Records If TXT records was created previously to indicate ownership its corresponding value will be added to the endpoints Labels map
