ARecord

class aws_cdk.aws_route53.ARecord(scope, id, *, target, zone, comment=None, delete_existing=None, record_name=None, ttl=None)

Bases: RecordSet

A DNS A record.

Resource:: AWS::Route53::RecordSet
ExampleMetadata:: infused

Example:

import aws_cdk.aws_apigateway as apigw

# zone: route53.HostedZone
# rest_api: apigw.LambdaRestApi


route53.ARecord(self, "AliasRecord",
    zone=zone,
    target=route53.RecordTarget.from_alias(targets.ApiGateway(rest_api))
)

Parameters:

scope (Construct) –
id (str) –
target (RecordTarget) – The target.
zone (IHostedZone) – The hosted zone in which to define the new record.
comment (Optional[str]) – A comment to add on the record. Default: no comment
delete_existing (Optional[bool]) – Whether to delete the same record set in the hosted zone if it already exists (dangerous!). This allows to deploy a new record set while minimizing the downtime because the new record set will be created immediately after the existing one is deleted. It also avoids “manual” actions to delete existing record sets. .. epigraph:: N.B.: this feature is dangerous, use with caution! It can only be used safely when deleteExisting is set to true as soon as the resource is added to the stack. Changing an existing Record Set’s deleteExisting property from false -> true after deployment will delete the record! Default: false
record_name (Optional[str]) – The subdomain name for this record. This should be relative to the zone root name. For example, if you want to create a record for acme.example.com, specify “acme”. You can also specify the fully qualified domain name which terminates with a “.”. For example, “acme.example.com.”. Default: zone root
ttl (Optional[Duration]) – The resource record cache time to live (TTL). Default: Duration.minutes(30)

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

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 (RemovalPolicy) –

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:: str

Attributes

domain_name: The domain name of the record.

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

node: The tree node.

stack: The stack in which this resource is defined.

Static Methods

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
