Types

type Config

type Config struct {
	Program            string
	Mode               string
	PropagationTimeout time.Duration
	PollingInterval    time.Duration
}

Config Provider configuration.

func NewDefaultConfig

func NewDefaultConfig() *Config

NewDefaultConfig returns a default configuration for the DNSProvider

type DNSProvider

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

DNSProvider adds and removes the record for the DNS challenge by calling a program with command-line parameters.

func NewDNSProvider

func NewDNSProvider() (*DNSProvider, error)

NewDNSProvider returns a new DNS provider which runs the program in the environment variable EXEC_PATH for adding and removing the DNS record.

func NewDNSProviderConfig

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

NewDNSProviderConfig returns a new DNS provider which runs the given configuration for adding and removing the DNS record.

func (*DNSProvider) CleanUp

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

CleanUp removes the TXT record matching the specified parameters

func (*DNSProvider) Present

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

Present creates a TXT record to fulfill the dns-01 challenge.

func (*DNSProvider) Sequential

func (d *DNSProvider) Sequential() time.Duration

Sequential All DNS challenges for this provider will be resolved sequentially. Returns the interval between each iteration.

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.
