PublicDnsNamespace

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

Bases: aws_cdk.core.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 (Optional[HealthCheckCustomConfig]) – 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 (Optional[HealthCheckConfig]) – 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

Return type

str

namespace_id

Namespace Id for the namespace.

Return type

str

namespace_name

A name for the namespace.

Return type

str
