Types

type Config

type Config struct {
	AuthEmail string
	AuthKey   string

	AuthToken string
	ZoneToken string

	TTL                int
	PropagationTimeout time.Duration
	PollingInterval    time.Duration
	HTTPClient         *http.Client
}

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() (*DNSProvider, error)

NewDNSProvider returns a DNSProvider instance configured for Cloudflare. Credentials must be passed in as environment variables:

Either provide CLOUDFLARE_EMAIL and CLOUDFLARE_API_KEY, or a CLOUDFLARE_DNS_API_TOKEN.

For a more paranoid setup, provide CLOUDFLARE_DNS_API_TOKEN and CLOUDFLARE_ZONE_API_TOKEN.

The email and API key should be avoided, if possible. Instead, set up an API token with both Zone:Read and DNS:Edit permission, and pass the CLOUDFLARE_DNS_API_TOKEN environment variable. You can split the Zone:Read and DNS:Edit permissions across multiple API tokens: in this case pass both CLOUDFLARE_ZONE_API_TOKEN and CLOUDFLARE_DNS_API_TOKEN accordingly.

func NewDNSProviderConfig

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

NewDNSProviderConfig return a DNSProvider instance configured for Cloudflare.

func (*DNSProvider) CreateRecord

func (d *DNSProvider) CreateRecord(Type, domain, value string) error

func (*DNSProvider) DeleteRecord

func (d *DNSProvider) DeleteRecord(Type string, domain string) error

func (*DNSProvider) ExistsRecord

func (d *DNSProvider) ExistsRecord(Type string, domain string) (bool, string, error)

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.
