DNS Providers

le-cert-server supports the DNS providers from the lego library. Credentials are configured under letsEncrypt.dnsCredentials using the normalized keys shown on each provider’s page, or the raw lego environment-variable names. They are passed to lego using strong types and are never written to the process environment.

Note: A few providers load their credentials through a third-party cloud SDK (for example AWS Route53/Lightsail, Google Cloud DNS, Azure DNS, Oracle Cloud, and OpenStack Designate). For those, the SDK discovers credentials from its own environment variables, shared credentials files, or instance metadata; only the non-secret options are listed on the provider page.
