» RFC 2136 DNS Challenge Provider

The rfc2136 DNS challenge provider can be used to perform DNS challenges for the acme_certificate resource with an RFC 2136-compatible DNS server.

For complete information on how to use this provider with the acme_certifiate resource, see here.

» Example

resource "acme_certificate" "certificate" {
  ...

  dns_challenge {
    provider = "rfc2136"
  }
}

» Argument Reference
