Namespace Amazon.CDK.AWS.ServiceDiscovery

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:

using Amazon.CDK;
using Amazon.CDK.AWS.ServiceDiscovery;

App app = new App();
Stack stack = new Stack(app, "aws-servicediscovery-integ");

HttpNamespace namespace = new HttpNamespace(stack, "MyNamespace", new HttpNamespaceProps {
    Name = "covfefe"
});

Service service1 = namespace.CreateService("NonIpService", new BaseServiceProps {
    Description = "service registering non-ip instances"
});

service1.RegisterNonIpInstance("NonIpInstance", new NonIpInstanceBaseProps {
    CustomAttributes = new Dictionary<string, string> { { "arn", "arn:aws:s3:::mybucket" } }
});

Service service2 = namespace.CreateService("IpService", new BaseServiceProps {
    Description = "service registering ip instances",
    HealthCheck = new HealthCheckConfig {
        Type = HealthCheckType.HTTP,
        ResourcePath = "/check"
    }
});

service2.RegisterIpInstance("IpInstance", new IpInstanceBaseProps {
    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:

using Amazon.CDK.AWS.EC2;
using Amazon.CDK.AWS.ElasticLoadBalancingV2;
using Amazon.CDK;
using Amazon.CDK.AWS.ServiceDiscovery;

App app = new App();
Stack stack = new Stack(app, "aws-servicediscovery-integ");

Vpc vpc = new Vpc(stack, "Vpc", new VpcProps { MaxAzs = 2 });

PrivateDnsNamespace namespace = new PrivateDnsNamespace(stack, "Namespace", new PrivateDnsNamespaceProps {
    Name = "boobar.com",
    Vpc = vpc
});

Service service = namespace.CreateService("Service", new DnsServiceProps {
    DnsRecordType = DnsRecordType.A_AAAA,
    DnsTtl = Duration.Seconds(30),
    LoadBalancer = true
});

ApplicationLoadBalancer loadbalancer = new ApplicationLoadBalancer(stack, "LB", new ApplicationLoadBalancerProps { Vpc = vpc, InternetFacing = true });

service.RegisterLoadBalancer("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:

using Amazon.CDK;
using Amazon.CDK.AWS.ServiceDiscovery;

App app = new App();
Stack stack = new Stack(app, "aws-servicediscovery-integ");

PublicDnsNamespace namespace = new PublicDnsNamespace(stack, "Namespace", new PublicDnsNamespaceProps {
    Name = "foobar.com"
});

Service service = namespace.CreateService("Service", new DnsServiceProps {
    Name = "foo",
    DnsRecordType = DnsRecordType.A,
    DnsTtl = Duration.Seconds(30),
    HealthCheck = new HealthCheckConfig {
        Type = HealthCheckType.HTTPS,
        ResourcePath = "/healthcheck",
        FailureThreshold = 2
    }
});

service.RegisterIpInstance("IpInstance", new IpInstanceBaseProps {
    Ipv4 = "54.239.25.192",
    Port = 443
});

app.Synth();

For DNS namespaces, you can also register instances to services with CNAME records:

using Amazon.CDK;
using Amazon.CDK.AWS.ServiceDiscovery;

App app = new App();
Stack stack = new Stack(app, "aws-servicediscovery-integ");

PublicDnsNamespace namespace = new PublicDnsNamespace(stack, "Namespace", new PublicDnsNamespaceProps {
    Name = "foobar.com"
});

Service service = namespace.CreateService("Service", new DnsServiceProps {
    Name = "foo",
    DnsRecordType = DnsRecordType.CNAME,
    DnsTtl = Duration.Seconds(30)
});

service.RegisterCnameInstance("CnameInstance", new CnameInstanceBaseProps {
    InstanceCname = "service.pizza"
});

app.Synth();
