I ran into a bit of an issue today while creating a certificate with CloudFormation. After kicking the stack off it ended up hanging on a step to create a domain verification entry in Route 53.
I had used this script multiple times for creating a certificate for a subdomain, but this time I included an apex domain as well. In order to narrow things down a little further I checked out the certificate via the console:
While the subdomain had passed the apex domain was still sitting in pending. Surprisingly, in Route53 the record DID exist. In order to get things moving again I manually deleted the record and then clicked “Create records in Route 53”.
This re-created the record I’d just deleted, and after a couple of minutes the domain validation passed and then the certificate was created:
This was a bit of a weird one that I have been unable to reproduce. I’m not certain why the DNS validation ended up hanging but retriggering the process seems to have resolved it.
Note that there are other legitimate reasons why your deployment might be hanging at this step:
When you use the
AWS::CertificateManager::Certificateresource 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 AWS 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 thehttps://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-certificatemanager-certificate.html
CREATE_IN_PROGRESSstate. 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.
