The CDK Construct Library for AWS::CertificateManager

AWS Certificate Manager Construct Library

---

---

AWS Certificate Manager (ACM) handles the complexity of creating, storing, and renewing public and private SSL/TLS X.509 certificates and keys that protect your AWS websites and applications. ACM certificates can secure singular domain names, multiple specific domain names, wildcard domains, or combinations of these. ACM wildcard certificates can protect an unlimited number of subdomains.

This package provides Constructs for provisioning and referencing ACM certificates which can be used with CloudFront and ELB.

After requesting a certificate, you will need to prove that you own the domain in question before the certificate will be granted. The CloudFormation deployment will wait until this verification process has been completed.

Because of this wait time, when using manual validation methods, it's better to provision your certificates either in a separate stack from your main service, or provision them manually and import them into your CDK application.

Note: There is a limit on total number of ACM certificates that can be requested on an account and region within a year. The default limit is 2000, but this limit may be (much) lower on new AWS accounts. See https://docs.aws.amazon.com/acm/latest/userguide/acm-limits.html for more information.

DNS validation

DNS validation is the preferred method to validate domain ownership, as it has a number of advantages over email validation. See also Validate with DNS in the AWS Certificate Manager User Guide.

If Amazon Route 53 is your DNS provider for the requested domain, the DNS record can be created automatically:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_certificatemanager as acm
import aws_cdk.aws_route53 as route53

my_hosted_zone = route53.HostedZone(self, "HostedZone",
    zone_name="example.com"
)
acm.Certificate(self, "Certificate",
    domain_name="hello.example.com",
    validation=acm.CertificateValidation.from_dns(my_hosted_zone)
)

If Route 53 is not your DNS provider, the DNS records must be added manually and the stack will not complete creating until the records are added.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
acm.Certificate(self, "Certificate",
    domain_name="hello.example.com",
    validation=acm.CertificateValidation.from_dns()
)

When working with multiple domains, use the CertificateValidation.fromDnsMultiZone():

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
example_com = route53.HostedZone(self, "ExampleCom",
    zone_name="example.com"
)
example_net = route53.HostedZone(self, "ExampelNet",
    zone_name="example.net"
)

cert = acm.Certificate(self, "Certificate",
    domain_name="test.example.com",
    subject_alternative_names=["cool.example.com", "test.example.net"],
    validation=acm.CertificateValidation.from_dns_multi_zone(
        text.example.com=example_com,
        cool.example.com=example_com,
        test.example.net=example_net
    )
)

Email validation

Email-validated certificates (the default) are validated by receiving an email on one of a number of predefined domains and following the instructions in the email.

See Validate with Email in the AWS Certificate Manager User Guide.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
acm.Certificate(self, "Certificate",
    domain_name="hello.example.com",
    validation=acm.CertificateValidation.from_email()
)

Cross-region Certificates

ACM certificates that are used with CloudFront -- or higher-level constructs which rely on CloudFront -- must be in the us-east-1 region. The DnsValidatedCertificate construct exists to faciliate creating these certificates cross-region. This resource can only be used with Route53-based DNS validation.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
acm.DnsValidatedCertificate(self, "CrossRegionCertificate",
    domain_name="hello.example.com",
    hosted_zone=my_hosted_zone,
    region="us-east-1"
)

Importing

If you want to import an existing certificate, you can do so from its ARN:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
arn = "arn:aws:..."
certificate = Certificate.from_certificate_arn(self, "Certificate", arn)

Sharing between Stacks

To share the certificate between stacks in the same CDK application, simply pass the Certificate object between the stacks.
