PowerDNS provider

Tested and confirmed to work with PowerDNS authoritative server 3.4.8 and 4.0.1. Refer to PowerDNS documentation instructions on how to enable the built-in API interface.

PowerDNS Notes:

• PowerDNS API does not currently support SSL, therefore you should take care to ensure that traffic between lego and the PowerDNS API is over a trusted network, VPN etc.
• In order to have the SOA serial automatically increment each time the _acme-challenge record is added/modified via the API, set SOA-EDIT-API to INCEPTION-INCREMENT for the zone in the domainmetadata table

Types

type Config

type Config struct {
	APIKey             string
	Host               *url.URL
	PropagationTimeout time.Duration
	PollingInterval    time.Duration
	TTL                int
	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 is an implementation of the acme.ChallengeProvider interface

func NewDNSProvider

func NewDNSProvider() (*DNSProvider, error)

NewDNSProvider returns a DNSProvider instance configured for pdns. Credentials must be passed in the environment variable: PDNS_API_URL and PDNS_API_KEY.

func NewDNSProviderConfig

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

NewDNSProviderConfig return a DNSProvider instance configured for pdns.

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.

type Record

type Record struct {
	Content  string `json:"content"`
	Disabled bool   `json:"disabled"`

	// pre-v1 API
	Name string `json:"name"`
	Type string `json:"type"`
	TTL  int    `json:"ttl,omitempty"`
}
