The CDK Construct Library for AWS::ServiceDiscovery
Project description
Amazon ECS Service Discovery Construct Library
---This module is part of the AWS Cloud Development Kit project.
This package contains constructs for working with AWS Cloud Map
AWS Cloud Map is a fully managed service that you can use to create and maintain a map of the backend services and resources that your applications depend on.
For further information on AWS Cloud Map, see the AWS Cloud Map documentation
HTTP Namespace Example
The following example creates an AWS Cloud Map namespace that supports API calls, creates a service in that namespace, and registers an instance to it:
# Example automatically generated. See https://github.com/aws/jsii/issues/826
import aws_cdk.core as cdk
import ...lib as servicediscovery
app = cdk.App()
stack = cdk.Stack(app, "aws-servicediscovery-integ")
namespace = servicediscovery.HttpNamespace(stack, "MyNamespace",
name="covfefe"
)
service1 = namespace.create_service("NonIpService",
description="service registering non-ip instances"
)
service1.register_non_ip_instance("NonIpInstance",
custom_attributes={"arn": "arn:aws:s3:::mybucket"}
)
service2 = namespace.create_service("IpService",
description="service registering ip instances",
health_check=HealthCheckConfig(
type=servicediscovery.HealthCheckType.HTTP,
resource_path="/check"
)
)
service2.register_ip_instance("IpInstance", {
"ipv4": "54.239.25.192"
})
app.synth()
Private DNS Namespace Example
The following example creates an AWS Cloud Map namespace that supports both API calls and DNS queries within a vpc, creates a service in that namespace, and registers a loadbalancer as an instance:
# Example automatically generated. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_ec2 as ec2
import aws_cdk.aws_elasticloadbalancingv2 as elbv2
import aws_cdk.core as cdk
import ...lib as servicediscovery
app = cdk.App()
stack = cdk.Stack(app, "aws-servicediscovery-integ")
vpc = ec2.Vpc(stack, "Vpc", max_azs=2)
namespace = servicediscovery.PrivateDnsNamespace(stack, "Namespace",
name="boobar.com",
vpc=vpc
)
service = namespace.create_service("Service",
dns_record_type=servicediscovery.DnsRecordType.A_AAAA,
dns_ttl=cdk.Duration.seconds(30),
load_balancer=True
)
loadbalancer = elbv2.ApplicationLoadBalancer(stack, "LB", vpc=vpc, internet_facing=True)
service.register_load_balancer("Loadbalancer", loadbalancer)
app.synth()
Public DNS Namespace Example
The following example creates an AWS Cloud Map namespace that supports both API calls and public DNS queries, creates a service in that namespace, and registers an IP instance:
# Example automatically generated. See https://github.com/aws/jsii/issues/826
import aws_cdk.core as cdk
import ...lib 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=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()
For DNS namespaces, you can also register instances to services with CNAME records:
# Example automatically generated. See https://github.com/aws/jsii/issues/826
import aws_cdk.core as cdk
import ...lib 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.CNAME,
dns_ttl=cdk.Duration.seconds(30)
)
service.register_cname_instance("CnameInstance",
instance_cname="service.pizza"
)
app.synth()
