AWS::Route53Resolver::ResolverRule - AWS CloudFormation

AWS::Route53Resolver::ResolverRule

For DNS queries that originate in your VPCs, specifies which Resolver endpoint the queries pass through, one domain name that you want to forward to your network, and the IP addresses of the DNS resolvers in your network.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "Type" : "AWS::Route53Resolver::ResolverRule", "Properties" : { "DomainName" : String, "Name" : String, "ResolverEndpointId" : String, "RuleType" : String, "Tags" : [ Tag, ... ], "TargetIps" : [ TargetAddress, ... ] } }

YAML

Type: AWS::Route53Resolver::ResolverRule Properties: DomainName: String Name: String ResolverEndpointId: String RuleType: String Tags: - Tag TargetIps: - TargetAddress

Properties

DomainName

DNS queries for this domain name are forwarded to the IP addresses that are specified in TargetIps. If a query matches multiple Resolver rules (example.com and www.example.com), the query is routed using the Resolver rule that contains the most specific domain name (www.example.com).

Required: Yes

Type: String

Minimum: 1

Maximum: 256

Update requires: Replacement

Name

The name for the Resolver rule, which you specified when you created the Resolver rule.

Required: No

Type: String

Maximum: 64

Pattern: (?!^[0-9]+$)([a-zA-Z0-9\-_' ']+)

Update requires: No interruption

ResolverEndpointId

The ID of the endpoint that the rule is associated with.

Required: No

Type: String

Minimum: 1

Maximum: 64

Update requires: No interruption

RuleType

When you want to forward DNS queries for specified domain name to resolvers on your network, specify FORWARD.

When you have a forwarding rule to forward DNS queries for a domain to your network and you want Resolver to process queries for a subdomain of that domain, specify SYSTEM.

For example, to forward DNS queries for example.com to resolvers on your network, you create a rule and specify FORWARD for RuleType. To then have Resolver process queries for apex.example.com, you create a rule and specify SYSTEM for RuleType.

Currently, only Resolver can create rules that have a value of RECURSIVE for RuleType.

Required: Yes

Type: String

Allowed values: FORWARD | RECURSIVE | SYSTEM

Update requires: Replacement

Tags

A list of the tag keys and values that you want to associate with the endpoint.

Required: No

Type: List of Tag

Maximum: 200

Update requires: No interruption

TargetIps

An array that contains the IP addresses and ports that an outbound endpoint forwards DNS queries to. Typically, these are the IP addresses of DNS resolvers on your network. Specify IPv4 addresses. IPv6 is not supported.

Required: No

Type: List of TargetAddress

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the ResolverRule object, which contains detailed information about the rule.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

The Amazon Resource Name (ARN) of the resolver rule, such as arn:aws:route53Resolver:us-east-1:123456789012:resolver-rule/resolver-rule-a1bzhi.

DomainName

DNS queries for this domain name are forwarded to the IP addresses that are specified in TargetIps. If a query matches multiple resolver rules (example.com and www.example.com), the query is routed using the resolver rule that contains the most specific domain name (www.example.com).

Name

A friendly name that lets you easily find a rule in the Resolver dashboard in the Route 53 console.

ResolverEndpointId

The ID of the outbound endpoint that the rule is associated with, such as rslvr-out-fdc049932dexample.

ResolverRuleId

When the value of RuleType is FORWARD, the ID that Resolver assigned to the resolver rule when you created it, such as rslvr-rr-5328a0899aexample. This value isn't applicable when RuleType is SYSTEM.

TargetIps

When the value of RuleType is FORWARD, the IP addresses that the outbound endpoint forwards DNS queries to, typically the IP addresses for DNS resolvers on your network. This value isn't applicable when RuleType is SYSTEM.

Examples

Create Resolver rule

The following example creates an Amazon Route 53 outbound resolver rule.
