» google_dns_keys

Get the DNSKEY and DS records of DNSSEC-signed managed zones. For more information see the official documentation and API.

» Example Usage

resource "google_dns_managed_zone" "foo" {
  name     = "foobar"
  dns_name = "foo.bar."

  dnssec_config {
    state         = "on"
    non_existence = "nsec3"

data "google_dns_keys" "foo_dns_keys" {
  managed_zone = google_dns_managed_zone.foo.id

output "foo_dns_ds_record" {
  description = "DS record of the foo subdomain."
  value       = data.google_dns_keys.foo_dns_keys.key_signing_keys[0].ds_record

» Argument Reference

The following arguments are supported:

  • managed_zone - (Required) The name or id of the Cloud DNS managed zone.

  • project - (Optional) The ID of the project in which the resource belongs. If project is not provided, the provider project is used.

» Attributes Reference

The following attributes are exported:

  • key_signing_keys - A list of Key-signing key (KSK) records. Structure is documented below. Additionally, the DS record is provided:

    • ds_record - The DS record based on the KSK record. This is used when delegating DNSSEC-signed subdomains.
  • zone_signing_keys - A list of Zone-signing key (ZSK) records. Structure is documented below.

The key_signing_keys and zone_signing_keys block supports:

  • algorithm - String mnemonic specifying the DNSSEC algorithm of this key. Immutable after creation time. Possible values are ecdsap256sha256, ecdsap384sha384, rsasha1, rsasha256, and rsasha512.

  • creation_time - The time that this resource was created in the control plane. This is in RFC3339 text format.

  • description - A mutable string of at most 1024 characters associated with this resource for the user's convenience.

  • digests - A list of cryptographic hashes of the DNSKEY resource record associated with this DnsKey. These digests are needed to construct a DS record that points at this DNS key. Each contains:

    • digest - The base-16 encoded bytes of this digest. Suitable for use in a DS resource record.
    • type - Specifies the algorithm used to calculate this digest. Possible values are sha1, sha256 and sha384
  • id - Unique identifier for the resource; defined by the server.

  • is_active - Active keys will be used to sign subsequent changes to the ManagedZone. Inactive keys will still be present as DNSKEY Resource Records for the use of resolvers validating existing signatures.

  • key_length - Length of the key in bits. Specified at creation time then immutable.

  • key_tag - The key tag is a non-cryptographic hash of the a DNSKEY resource record associated with this DnsKey. The key tag can be used to identify a DNSKEY more quickly (but it is not a unique identifier). In particular, the key tag is used in a parent zone's DS record to point at the DNSKEY in this child ManagedZone. The key tag is a number in the range [0, 65535] and the algorithm to calculate it is specified in RFC4034 Appendix B.

  • public_key - Base64 encoded public half of this key.
