Before you begin

You must have or create a managed zone before you can create a resource record set. For details about how to create a managed zone, in which you can create your resource record set, seeCreate a managed zone.

Add a resource record set

To add a resource record set, follow these steps:

Console

  1. In the Google Cloud console, go to the Cloud DNS zones page.
    Go to Cloud DNS zones
  2. Click the name of the managed zone that you want to add the record to.
  3. On the Zone details page, click Add standard.
  4. On the Create record set page, in the DNS name field, enter the subdomain of the DNS zone—for example, mail. The trailing dot is automatically added at the end.
    To create a wildcard DNS record, enter an asterisk—for example,*.example.com.
    The at sign (@) does not automatically create an apex record. To create a resource record at the domain apex, leave the DNS namefield blank.
  5. Select the Resource record type—for example, MX.
  6. In the TTL field, enter a numeric value for the resource record's time to live, which is the amount of time that it can be cached. This value must be a positive integer.
  7. From the TTL unit menu, select the unit of time—for example,minutes.
  8. Depending on the resource record type that you have selected,populate the remaining fields.
  9. To enter additional information, click Add item.
  10. Click Create.

gcloud

To add a resource record set, use thegcloud dns record-sets create command:

gcloud dns record-sets create RRSET_NAME
--rrdatas=RR_DATA
--ttl=TTL
--type=RRSET_TYPE
--zone=MANAGED_ZONE

Replace the following:

API

To add a resource record set, use theresourceRecordSets.create methodmethod:

POST https://dns.googleapis.com/dns/v1/projects/PROJECT_ID/managedZones/MANAGED_ZONE/rrsets { "name": "RRSET_NAME", "type": "RRSET_TYPE", "ttl": TTL, "rrdatas": [ RR_DATA ] }

Replace the following:

Add a collection of resource record sets in a transaction

You can add multiple resource record sets by creating a transaction that specifies the changes. A transaction is a group of one or more DNS record changes that must be applied as a unit. The entire transaction either succeeds or fails, ensuring your data is never left in an inconsistent state. You can create a transaction only by using the gcloud CLI or the Cloud DNS API.

To create a transaction, follow these steps:

gcloud

  1. To start a transaction, use thegcloud dns record-sets transaction start command:
    gcloud dns record-sets transaction start \
    --zone=MANAGED_ZONE
    Replace MANAGED_ZONE with the name of the managed zone whose resource record sets you want to manage—for example,my-zone-name.
  2. To add a resource record set as part of a transaction, use thegcloud dns record-sets transaction add command:
    gcloud dns record-sets transaction add RR_DATA \
    --name=DNS_NAME \
    --ttl=TTL \
    --type=RECORD_TYPE \
    --zone=MANAGED_ZONE
    Replace the following:
    • RR_DATA: an arbitrary value associated with the resource record set—for example, 198.51.100.5; you can also enter multiple values, rrdata1 rrdata2 rrdata3—for example, 198.51.100.5 10.2.3.4...
    • DNS_NAME: the DNS or domain name of the record set to add—for example, test.example.com
    • TTL: the time to live (TTL) for the record set in number of seconds—for example, 300
    • RECORD_TYPE: the record type—for example, A.
    • MANAGED_ZONE: the name of the managed zone whose resource record sets you want to manage—for example, my-zone-name
  3. To execute the transaction, use thegcloud dns record-sets transaction execute command:
    gcloud dns record-sets transaction execute \
    --zone=MANAGED_ZONE
  4. To add a wildcard transaction, use thegcloud dns record-sets transaction add command:
    gcloud dns record-sets transaction add \
    --zone=MANAGED_ZONE \
    --name=WILDCARD_DNS_NAME \
    --type=RECORD_TYPE \
    --ttl=TTL
    Replace the following:
    • MANAGED_ZONE: the name of the managed zone whose resource record sets you want to manage—for example, my-zone-name
    • WILDCARD_DNS_NAME: the DNS or domain name of the resource record set that you want to add—for example, *.example.com.(note the trailing dot)
    • RECORD_TYPE: the record type—for example, CNAME.
    • TTL: the TTL for the record set in number of seconds—for example, 300

API

To create a transaction with new resource record sets, use thechanges.create method:

POST https://dns.googleapis.com/dns/v1/projects/PROJECT_ID/managedZones/MANAGED_ZONE/changes { "deletions": [] "additions": [ { "name": DNS_NAME, "type": RECORD_TYPE, "ttl": TTL, "rrdatas": [ RR_DATA ] } ] }

Replace the following:

To deliver email to your domain, you must add MX records to your zone. If you use Google Workspace as your Simple Mail Transfer Protocol (SMTP) provider, see the Set up Google Workspace MXrecords support page. Otherwise, use the MX record details from your provider and follow the setup process described for Google Workspace.

View resource record sets for a zone

Replace the following:

Delete resource record sets

When you delete resource record sets, their DNS records are permanently removed; they cannot be recovered. To prevent losing your DNS records, export the resource record sets before deletion. For information about how to export resource record sets, seeImport and export resource record sets.

Cloud DNS public zones are authoritative, and the name server (NS) and start of authority (SOA) record types are located at the zone apex, which is the root of that domain. Cloud DNS automatically creates NS and SOA records at the zone apex. These records can't be deleted by using the Cloud DNS API and are automatically deleted when the zone is deleted. For more information, see RFC 1034.

To delete resource record sets, follow these steps:

Console

  1. In the Google Cloud console, go to the Cloud DNS page.
    Go to Cloud DNS zones
    Records for the zone are listed on the Zone details page.
  2. To delete resource record sets in a zone, click the name of the zone.
  3. Next to the resource record sets that you want to delete, select the checkbox.
  4. Click Delete record sets.

gcloud

To delete an existing resource record set, use thegcloud dns record-sets delete command:

gcloud dns record-sets delete RRSET_NAME
--type=RRSET_TYPE
--zone=MANAGED_ZONE

Replace the following:

API

To delete an existing resource record set, use theresourceRecordSets.delete method:

DELETE https://dns.googleapis.com/dns/v1/projects/PROJECT_ID/managedZones/MANAGED_ZONE/rrsets/RRSET_NAME/RRSET_TYPE

Replace the following:

Import and export resource record sets

To copy resource record sets into and out of a managed zone, you can use import andexport commands. You can import from and export to either the BIND zone file format or the YAML file format.

gcloud

  1. To import a resource record set, use thedns record-sets import command:
    gcloud dns record-sets import -z=ZONE_NAME
    If you want to specify the file format of the zone file, use the previous command with the --zone-file-format flag. If you omit the flag, you must provide a YAML format zone file.
    Replace ZONE_NAME with a new name for your zone.
    • When you use the gcloud dns record-sets import command with the--replace-origin-ns flag, it replaces the NS records for the zone with the NS records specified in the zone file. These records must match the name serversassigned by Cloud DNS to host the zone. They must also match the NS records specified in the parent (delegating) zone. By default, Cloud DNS does not overwrite NSrecords. If you use this flag, you must verify that the NS records are correct.
    • When you import record sets as a BIND zone-formatted file, remove the at sign (@) that denotes the zone's apex. In the BIND zone-formatted file, for a DNS name like example.com, the at sign (@) refers to example.com.. However, in Cloud DNS, the at sign (@) is treated literally when defining record names. To create a resource record set for the zone's apex in Cloud DNS, use the full domain name—for example, example.com..
      in.smtp IN MX 5 gmail-smtp-in.l.google.com
      in.smtp.example.com. IN MX 5 gmail-smtp-in.l.google.com.example.com.
      To import your zone files, add a trailing dot (.) to the end of any domain names that must be fully qualified.
  2. To export a resource record set, use thedns record-sets export command. To specify that the resource record sets are exported into a BIND zone-formatted file, use the --zone-file-format flag. For example:
    example.com. 21600 IN NS ns-gcp-private.googledomains.com.
    example.com. 21600 IN SOA ns-gcp-private.googledomains.com.
    cloud-dns-hostmaster.google.com. 1 21600 3600 259200 300
    host1.example.com. 300 IN A 192.0.2.91
    If you omit the --zone-file-format flag,export exports the resource record set into a YAML-formatted records file:
    gcloud dns record-sets export example.zone -z=examplezonename
    For example:
---  
kind: dns#resourceRecordSet  
name: example.com.  
rrdatas:  
- ns-gcp-private.googledomains.com.  
ttl: 21600  
type: NS  
---  
kind: dns#resourceRecordSet  
name: example.com.  
rrdatas:  
- ns-gcp-private.googledomains.com. cloud-dns-hostmaster.google.com. 1 21600 3600 259200 300  
ttl: 21600  
type: SOA  
---  
kind: dns#resourceRecordSet  
name: host1.example.com.  
rrdatas:  
- 192.0.2.91  
ttl: 300  
type: A

Cloud DNS supports the ALIAS record type, which isn't a standard DNS record type and isn't supported in BIND. If you're exporting resource record sets to BIND, ALIAS records are skipped. If a zone has a routing policy, it is exported as a record with empty resource record data (rrdata).
