This component is responsible for requesting an ACM certificate for a domain and adding a CNAME record to the DNS zone to complete certificate validation.

The ACM component is to manage an unlimited number of certificates, predominantly for vanity domains. While the dns-primary component has the ability to generate ACM certificates, it is very opinionated and can only manage one zone. In reality, companies have many branded domains associated with a load balancer, so we need to be able to generate more complicated certificates.

We have, as a convenience, the ability to create an ACM certificate as part of creating a DNS zone, whether primary or delegated. That convenience is limited to creating example.com and *.example.com when creating a zone for example.com. For example, Acme has delegated acct.acme.com and in addition to *.acct.acme.com needed an ACM certificate for *.usw2.acct.acme.com, so we use the ACM component to provision that, rather than extend the DNS primary or delegated components to take a list of additional certificates. Both are different views on the Single Responsibility Principle.

Usage

Stack Level: Global or Regional

Here's an example snippet for how to use this component.

components:
  terraform:
    acm:
      settings:
        spacelift:
          workspace_enabled: true
      vars:
        enabled: true
        domain_name: acme.com
        process_domain_validation_options: false
        validation_method: DNS
        # NOTE: The following subject alternative name is automatically added by the module.
        #       Additional entries can be added by providing this input.
        # subject_alternative_names:
        #   - "*.acme.com"
