Overview

Package azure implements a DNS provider for solving the DNS-01 challenge using azure DNS. Azure doesn't like trailing dots on domain names, most of the acme code does.

Types

type Config

type Config struct {
	// optional if using instance metadata service
	ClientID     string
	ClientSecret string
	TenantID     string

	SubscriptionID string
	ResourceGroup  string
	PrivateZone    bool

	MetadataEndpoint        string
	ResourceManagerEndpoint string
	ActiveDirectoryEndpoint string

	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 implements the challenge.Provider interface.

func NewDNSProvider

func NewDNSProvider() (*DNSProvider, error)

NewDNSProvider returns a DNSProvider instance configured for azure. Credentials can be passed in the environment variables: AZURE_ENVIRONMENT, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, AZURE_SUBSCRIPTION_ID, AZURE_TENANT_ID, AZURE_RESOURCE_GROUP If the credentials are _not_ set via the environment, then it will attempt to get a bearer token via the instance metadata service. see: https://github.com/Azure/go-autorest/blob/v10.14.0/autorest/azure/auth/auth.go#L38-L42

func NewDNSProviderConfig

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

NewDNSProviderConfig return a DNSProvider instance configured for Azure.

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.
