PublicDnsNamespace

class aws_cdk.aws_servicediscovery.PublicDnsNamespace(scope, id, *, name, description=None)

Bases: Resource

Define a Public DNS Namespace.

ExampleMetadata: lit=test/integ.service-with-public-dns-namespace.lit.ts infused

Example:

import aws_cdk.core as cdk
import aws_cdk.aws_servicediscovery as servicediscovery

app = cdk.App()
stack = cdk.Stack(app, "aws-servicediscovery-integ")

namespace = servicediscovery.PublicDnsNamespace(stack, "Namespace",
    name="foobar.com"
)

service = namespace.create_service("Service",
    name="foo",
    dns_record_type=servicediscovery.DnsRecordType.A,
    dns_ttl=cdk.Duration.seconds(30),
    health_check=servicediscovery.HealthCheckConfig(
        type=servicediscovery.HealthCheckType.HTTPS,
        resource_path="/healthcheck",
        failure_threshold=2
    )
)

service.register_ip_instance("IpInstance",
    ipv4="54.239.25.192",
    port=443
)

app.synth()

Parameters

scope (Construct) –
id (str) –
name (str) – A name for the Namespace.
description (Optional[str]) – A description of the Namespace. Default: none

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

create_service(id, *, dns_record_type=None, dns_ttl=None, load_balancer=None, routing_policy=None, custom_health_check=None, description=None, health_check=None, name=None)

Creates a service within the namespace.

Parameters

id (str) –
dns_record_type (Optional[DnsRecordType]) – The DNS type of the record that you want AWS Cloud Map to create. Supported record types include A, AAAA, A and AAAA (A_AAAA), CNAME, and SRV. Default: A
dns_ttl (Optional[Duration]) – The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. Default: Duration.minutes(1)
load_balancer (Optional[bool]) – Whether or not this service will have an Elastic LoadBalancer registered to it as an AliasTargetInstance. Setting this to true correctly configures the routingPolicy and performs some additional validation. Default: false
routing_policy (Optional[RoutingPolicy]) – The routing policy that you want to apply to all DNS records that AWS Cloud Map creates when you register an instance and specify this service. Default: WEIGHTED for CNAME records and when loadBalancer is true, MULTIVALUE otherwise
custom_health_check (Union[HealthCheckCustomConfig, Dict[str, Any], None]) – Structure containing failure threshold for a custom health checker. Only one of healthCheckConfig or healthCheckCustomConfig can be specified. See: https://docs.aws.amazon.com/cloud-map/latest/api/API_HealthCheckCustomConfig.html Default: none
description (Optional[str]) – A description of the service. Default: none
health_check (Union[HealthCheckConfig, Dict[str, Any], None]) – Settings for an optional health check. If you specify health check settings, AWS Cloud Map associates the health check with the records that you specify in DnsConfig. Only one of healthCheckConfig or healthCheckCustomConfig can be specified. Not valid for PrivateDnsNamespaces. If you use healthCheck, you can only register IP instances to this service. Default: none
name (Optional[str]) – A name for the Service. Default: CloudFormation-generated name

Return type

Service

to_string()

Returns a string representation of this construct.

Return type: str

Attributes

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.

Return type: ResourceEnvironment

namespace_arn

Namespace Arn for the namespace.

Return type: str

namespace_id

Namespace Id for the namespace.

Return type: str

namespace_name

A name for the namespace.

Return type: str

node

The construct tree node associated with this construct.

Return type: ConstructNode

public_dns_namespace_arn

true

Type: attribute
Return type: str

public_dns_namespace_id

true

Type: attribute
Return type: str

public_dns_namespace_name

true

Type: attribute
Return type: str

stack

The stack in which this resource is defined.

Return type: Stack

type

Type of the namespace.

Return type: NamespaceType

Static Methods

classmethod from_public_dns_namespace_attributes(scope, id, *, namespace_arn, namespace_id, namespace_name)

Parameters

scope (Construct) –
