Types

type Config

type Config struct {
	RAMRole            string
	APIKey             string
	SecretKey          string
	SecurityToken      string
	RegionID           string
	PropagationTimeout time.Duration
	PollingInterval    time.Duration
	TTL                int
	HTTPTimeout        time.Duration
}

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 implements the challenge.Provider interface.

func NewDNSProvider

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

NewDNSProvider returns a DNSProvider instance configured for Alibaba Cloud DNS. - If you're using the instance RAM role, the RAM role environment variable must be passed in: ALICLOUD_RAM_ROLE. - Other than that, credentials must be passed in the environment variables: ALICLOUD_ACCESS_KEY, ALICLOUD_SECRET_KEY, and optionally ALICLOUD_SECURITY_TOKEN.

func NewDNSProviderConfig

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

NewDNSProviderConfig return a DNSProvider instance configured for alidns.

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) 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.
