1. Auto-Renewable Certificates for AI Application Domains on ACM


    To set up auto-renewable certificates for your AI application domains using AWS Certificate Manager (ACM), you'll need to request a certificate and then validate that you own or control the domains listed in the certificate request. When you request a certificate, ACM tries to renew the certificate before it expires, as long as the certificate is in use and your domain validation records remain in place.

    Below is a Pulumi program in Python that demonstrates how to create an auto-renewable certificate with AWS Certificate Manager (ACM). This program will:

    1. Create an ACM certificate for your domain.
    2. Set up DNS validation for the certificate. This example assumes you are using a Route53 hosted zone for DNS.
    3. Automatically validate the certificate by creating the necessary DNS records in your Route53 hosted zone.

    Please replace "my-app.com" and "www.my-app.com" with your domain and subdomain, and HOSTED_ZONE_ID with your actual Route53 hosted zone ID. The comments in the code will guide you through the process.

    import pulumi import pulumi_aws as aws # Replace these with your domain name and hosted zone ID domain_name = "my-app.com" subdomain_name = "www.my-app.com" hosted_zone_id = "HOSTED_ZONE_ID" # Request a certificate for your domain cert = aws.acm.Certificate("myDomainCert", domain_name=domain_name, validation_method="DNS", subject_alternative_names=[subdomain_name], tags={ "Name": "myDomainCert" }) # Get the Route53 Hosted Zone by the given zone ID hosted_zone = pulumi.Output.all(hosted_zone_id).apply(lambda args: aws.route53.get_zone(id=args[0])) # Create the necessary DNS records to validate our domain and thus prove to ACM that we own the domain def create_dns_record(args): domain, validation_record = args return aws.route53.Record(f"{domain}_validation", name=validation_record.domain_name, type=validation_record.record_type, zone_id=hosted_zone.id, records=[validation_record.record_value], ttl=60) # Loop over each challenge DNS record provided by the ACM certificate and create corresponding DNS records in Route53 validation_records = pulumi.Output.all( cert.domain_validation_options.apply(lambda o: o[0])).apply(create_dns_record) # Wait for the ACM certificate to be validated upon DNS record propagation certificate_validation = aws.acm.CertificateValidation("certValidation", certificate_arn=cert.arn, validation_record_fqdns=validation_records.apply(lambda records: [record.fqdn])) # Finally, export the ARN of the validated certificate, which you can then use to set up resources like HTTPS listeners or CloudFront distributions pulumi.export("certificate_arn", certificate_validation.certificate_arn)

    This program defines three fundamental resources:

    • ACM Certificate: This initiates the certificate request for your domain with ACM and specifies DNS validation.
    • DNS Validation Records: To automate domain validation, DNS records are created in Route53 based on the details provided by ACM. This proves you control the domain.
    • Certificate Validation: This resource is
