AWS::CertificateManager::Certificate - AWS CloudFormation


The AWS::CertificateManager::Certificate resource requests an AWS 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 AWS Certificate Manager API Reference.


When you use the AWS::CertificateManager::Certificate resource in an AWS CloudFormation stack, the stack will remain in the CREATE_IN_PROGRESS state. Further stack operations will be 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 Use Email to Validate Domain Ownership and Use DNS to Validate Domain Ownership.
