AWS::CertificateManager::Certificate - Amazon CloudFormation
SyntaxPropertiesReturn valuesExamples
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

AWS::CertificateManager::Certificate

The AWS::CertificateManager::Certificate resource requests an Amazon Certificate Manager (ACM) certificate that you can use to enable secure connections. For example, you can deploy an ACM certificate to an Elastic Load Balancer to enable HTTPS support. For more information, see RequestCertificate in the Amazon Certificate Manager API Reference.

Important

When you use the AWS::CertificateManager::Certificate resource in a CloudFormation stack, domain validation is handled automatically if all three of the following are true: The certificate domain is hosted in Amazon Route 53, the domain resides in your Amazon Web Services account, and you are using DNS validation.

However, if the certificate uses email validation, or if the domain is not hosted in Route 53, then the stack will remain in the CREATE_IN_PROGRESS state. Further stack operations are delayed until you validate the certificate request, either by acting upon the instructions in the validation email, or by adding a CNAME record to your DNS configuration. For more information, see Option 1: DNS Validation and Option 2: Email Validation.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::CertificateManager::Certificate",
  "Properties" : {
      "CertificateAuthorityArn" : String,
      "CertificateTransparencyLoggingPreference" : String,
      "DomainName" : String,
      "DomainValidationOptions" : [ DomainValidationOption, ... ],
      "SubjectAlternativeNames" : [ String, ... ],
      "Tags" : [ Tag, ... ],
      "ValidationMethod" : String
    }
}

YAML

Type: AWS::CertificateManager::Certificate
Properties: 
  CertificateAuthorityArn: String
  CertificateTransparencyLoggingPreference: String
  DomainName: String
  DomainValidationOptions: 
    - DomainValidationOption
  SubjectAlternativeNames: 
    - String
  Tags: 
    - Tag
  ValidationMethod: String

Properties

CertificateAuthorityArn

The Amazon Resource Name (ARN) of the private certificate authority (CA) that will be used to issue the certificate. If you do not provide an ARN and you are trying to request a private certificate, ACM will attempt to issue a public certificate. For more information about private CAs, see the Amazon Private Certificate Authority user guide. The ARN must have the following form:

arn:aws:acm-pca:region:account:certificate-authority/12345678-1234-1234-1234-123456789012

Required: No

Type: String

Minimum: 20

Maximum: 2048

Pattern: arn:[\w+=/,.@-]+:acm-pca:[\w+=/,.@-]*:[0-9]+:[\w+=,.@-]+(/[\w+=,.@-]+)*

Update requires: Replacement

CertificateTransparencyLoggingPreference

You can opt out of certificate transparency logging by specifying the DISABLED option. Opt in by specifying ENABLED.

If you do not specify a certificate transparency logging preference on a new CloudFormation template, or if you remove the logging preference from an existing template, this is the same as explicitly enabling the preference.

Changing the certificate transparency logging preference will update the existing resource by calling UpdateCertificateOptions on the certificate. This action will not create a new resource.

Required: No

Type: String

Allowed values: DISABLED | ENABLED

Update requires: No interruption

DomainName

The fully qualified domain name (FQDN), such as www.example.com, with which you want to secure an ACM certificate. Use an asterisk (*) to create a wildcard certificate that protects several sites in the same domain. For example, *.example.com protects www.example.com, site.example.com, and images.example.com.

Required: Yes

Type: String

Minimum: 1

Maximum: 253

Pattern: ^(\*\.)?(((?!-)[A-Za-z0-9-]{0,62}[A-Za-z0-9])\.)+((?!-)[A-Za-z0-9-]{1,62}[A-Za-z0-9])$

Update requires: Replacement

DomainValidationOptions

Domain information that domain name registrars use to verify your identity.

Important

In order for a AWS::CertificateManager::Certificate to be provisioned and validated in CloudFormation automatically, the `DomainName` property needs to be identical to one of the `DomainName` property supplied in DomainValidationOptions, if the ValidationMethod is **DNS**. Failing to keep them like-for-like will result in failure to create the domain validation records in Route53.

Required: No

Type: List of DomainValidationOption

Maximum: 100

Update requires: Replacement

SubjectAlternativeNames

Additional FQDNs to be included in the Subject Alternative Name extension of the ACM certificate. For example, you can add www.example.net to a certificate for which the DomainName field is www.example.com if users can reach your site by using either name.

Required: No

Type: List of String

Maximum: 100

Update requires: Replacement

Tags

Key-value pairs that can identify the certificate.

Required: No

Type: List of Tag

Maximum: 50

Update requires: No interruption

ValidationMethod

The method you want to use to validate that you own or control the domain associated with a public certificate. You can validate with DNS or validate with email. We recommend that you use DNS validation.

If not specified, this property defaults to email validation.

Required: No

Type: String

Allowed values: DNS | EMAIL

Update requires: Replacement

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Reffunction, Refreturns the certificate's Amazon Resource Name (ARN).

For more information about using the Reffunction, see Ref.

Declaring an Amazon Certificate Manager Certificate Resource

The following example shows how to declare an AWS::CertificateManager::Certificate resource to create an ACM certificate.

JSON

{
   "Resources":{
      "MyCertificate":{
         "Type":"AWS::CertificateManager::Certificate",
         "Properties":{
            "DomainName":"example.com",
            "ValidationMethod":"DNS"
         }
      }
   }
}

YAML

Resources: 
  MyCertificate: 
    Type: "AWS::CertificateManager::Certificate"
    Properties: 
      DomainName: example.com
      ValidationMethod: DNS
