Types

type Config

type Config struct {
	CustomerName       string
	UserName           string
	Password           string
	HTTPClient         *http.Client
	PropagationTimeout time.Duration
	PollingInterval    time.Duration
	TTL                int
}

Config is used to configure the creation of the DNSProvider

func NewDefaultConfig

func NewDefaultConfig() *Config

NewDefaultConfig returns a default configuration for the DNSProvider

type DNSProvider

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

DNSProvider is an implementation of the challenge.Provider interface that uses Dyn's Managed DNS API to manage TXT records for a domain.

func NewDNSProvider

func NewDNSProvider() (*DNSProvider, error)

NewDNSProvider returns a DNSProvider instance configured for Dyn DNS. Credentials must be passed in the environment variables: DYN_CUSTOMER_NAME, DYN_USER_NAME and DYN_PASSWORD.

func NewDNSProviderConfig

func NewDNSProviderConfig(config *Config) (*DNSProvider, error)

NewDNSProviderConfig return a DNSProvider instance configured for Dyn DNS

func (*DNSProvider) CleanUp

func (d *DNSProvider) CleanUp(domain, token, fqdn, value string) error

CleanUp removes the TXT record matching the specified parameters

func (*DNSProvider) Present

func (d *DNSProvider) Present(domain, token, fqdn, value string) error

Present creates a TXT record using the specified parameters

func (*DNSProvider) Timeout

func (d *DNSProvider) Timeout() (timeout, interval time.Duration)

Timeout returns the timeout and interval to use when checking for DNS propagation. Adjusting here to cope with spikes in propagation times.
