Roles and permissions

Google Cloud offers Identity and Access Management (IAM), which lets you give more granular access to specific Google Cloud resources and prevents unwanted access to other resources. This page describes the Cloud DNS API roles. For a detailed description of IAM, see the Identity and Access Management documentation.

IAM lets you adopt the security principle of least privilege so that you grant only the necessary access to your resources.

IAM lets you control who has what permissions to which resources by setting IAM policies. IAM policies grant specific roles to a user, giving the user certain permissions. For example, a particular user might need to create and modify Domain Name System (DNS) record resources. You would then give that user (who) the /roles/dns.admin role, which has the dns.changes.create and dns.resourceRecordSets.create permissions (what) so that they can create and update resource record sets (which). In contrast, a support department might only need to view existing resource record sets, so they would get a /roles/dns.reader role.

Cloud DNS supports IAM permissions at the project level and individual DNS zone level. The default permission is at the project level. To configure permissions at the individual DNS zone (or resource) level, see Create a zone with specific IAM permissions.

Permissions and roles

Every Cloud DNS API method requires the caller to have the necessary IAM permissions. Permissions are assigned by granting roles to a user, group, or service account. In addition to the basic roles Owner, Editor, and Viewer, you can grant Cloud DNS API roles to the users of your project.

Permissions

The following table lists the permissions that the caller must have to call each method.

Method Required permission(s)
dns.changes.create To create a resource record, set both dns.changes.create and dns.resourceRecordSets.create on the project containing the record set.

To update a resource record, set both dns.changes.create and dns.resourceRecordSets.update on the project containing the record set.

To delete a resource record, set both dns.changes.create and dns.resourceRecordSets.delete on the project containing the record set.

dns.changes.get dns.changes.get on the project containing the managed zone.
dns.changes.list dns.changes.list on the project containing the managed zone.
dns.dnsKeys.get dns.dnsKeys.get on the project containing the managed zone.
dns.dnsKeys.list dns.dnsKeys.list on the project containing the managed zone.
dns.managedZoneOperations.get dns.managedZoneOperations.get on the project containing the managed zone.
dns.managedZoneOperations.list dns.managedZoneOperations.list on the project containing the managed zone.
dns.managedZones.create dns.managedZones.create on the project containing the managed zone.

If you are creating a private zone, you also need dns.networks.bindPrivateDNSZone and dns.networks.targetWithPeeringZone on each project with a VPC network authorized to access the zone.

If you are creating a private zone with GKE integration, you also need dns.gkeClusters.bindPrivateDNSZone to configure a GKE cluster scope.
dns.managedZones.delete dns.managedZones.delete on the project containing the managed zone.
dns.managedZones.get dns.managedZones.get on the project containing the managed zone.
dns.managedZones.list dns.managedZones.list on the project containing the managed zone.
dns.managedZones.update dns.managedZones.update on the project containing the managed zone.

If you are creating a private zone, you also need dns.networks.bindPrivateDNSZone and dns.networks.targetWithPeeringZone on each project with a VPC network authorized to access the zone.

If you are creating a private zone with GKE integration, you also need dns.gkeClusters.bindPrivateDNSZone to configure a GKE cluster scope.
dns.policies.create dns.policies.create on the project containing the policy.

If the policy is created on a VPC network, you also need dns.networks.bindPrivateDNSPolicy for each project containing each VPC network.
dns.policies.delete dns.policies.delete on the project containing the policy.
dns.policies.get dns.policies.get on the project containing the policy.
dns.policies.list dns.policies.list on the project containing the policy.
dns.policies.update dns.policies.update on the project containing the policy.

If the policy is updated to be on a VPC network, you also need dns.networks.bindPrivateDNSPolicy for each project containing each VPC network.
dns.projects.get dns.projects.get on the project.
dns.resourceRecordSets.create dns.resourceRecordSets.create on the project containing the record set.
dns.resourceRecordSets.delete dns.resourceRecordSets.delete on the project containing the record set.
dns.resourceRecordSets.get dns.resourceRecordSets.get on the project containing the record set.
dns.resourceRecordSets.list dns.resourceRecordSets.list on the project containing the managed zone.
dns.resourceRecordSets.update dns.resourceRecordSets.update and dns.changes.create on the project containing the record set.
dns.responsePolicies.create dns.responsePolicies.create on the project containing the response policy.

You also need dns.networks.bindDNSResponsePolicy to validate the request.

If you want to create a response policy attached to a GKE cluster, you need dns.gkeClusters.bindDNSResponsePolicy.

dns.responsePolicies.delete dns.responsePolicies.delete on the project containing the response policy.
dns.responsePolicies.get dns.responsePolicies.get on the project containing the response policy.
dns.responsePolicies.list dns.responsePolicies.list on the project.
dns.responsePolicies.update dns.responsePolicies.update on the project containing the response policy.

You also need dns.networks.bindDNSResponsePolicy to validate the request.

If you want to create a response policy attached to a GKE cluster, you need dns.gkeClusters.bindDNSResponsePolicy.
dns.responsePolicyRules.create dns.responsePolicyRules.create on the project containing the response policy rule.
dns.responsePolicyRules.delete dns.responsePolicyRules.delete on the project containing the response policy rule.
dns.responsePolicyRules.get dns.responsePolicyRules.get on the project containing the response policy rule.
dns.responsePolicyRules.list dns.responsePolicyRules.list on the project containing the response policy.
dns.responsePolicyRules.update dns.responsePolicyRules.update on the project containing the response policy rule.
networksecurity.dnsThreatDetectors.list networksecurity.dnsThreatDetectors.list on the project where the VPC networks are monitored for threats.
networksecurity.dnsThreatDetectors.get networksecurity.dnsThreatDetectors.get on the project where the VPC networks are monitored for threats.
