CfnResolverRule

class aws_cdk.aws_route53resolver.CfnResolverRule(scope, id, *, domain_name, rule_type, name=None, resolver_endpoint_id=None, tags=None, target_ips=None)

Bases: aws_cdk.core.CfnResource

A 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.

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_route53resolver as route53resolver

cfn_resolver_rule = route53resolver.CfnResolverRule(self, "MyCfnResolverRule",
    domain_name="domainName",
    rule_type="ruleType",

    # the properties below are optional
    name="name",
    resolver_endpoint_id="resolverEndpointId",
    tags=[CfnTag(
        key="key",
        value="value"
    )],
    target_ips=[route53resolver.CfnResolverRule.TargetAddressProperty(
        ip="ip",

        # the properties below are optional
        port="port"
    )]
)

Create a new AWS::Route53Resolver::ResolverRule.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • domain_name (str) – 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).

  • rule_type (str) – 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 .

  • name (Optional[str]) – The name for the Resolver rule, which you specified when you created the Resolver rule.

  • resolver_endpoint_id (Optional[str]) – The ID of the endpoint that the rule is associated with.

  • tags (Optional[Sequence[CfnTag]]) – Route 53 Resolver doesn’t support updating tags through CloudFormation.

  • target_ips (Union[IResolvable, Sequence[Union[IResolvable, TargetAddressProperty]], None]) – 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.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

Any

inspect(inspector)

Parameters

  • tree inspector to collect and process attributes.

Return type
