Terraform module to request an ACM certificate for a domain and add a CNAME record to the DNS zone to complete certificate validation
Tip
Cloud Posse uses atmos
to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.
Watch demo of using Atmos with Terraform
![](https://github.com/cloudposse/atmos/raw/master/docs/demo.gif?raw=true)
Example of running
atmos
to manage infrastructure from our Quick Start tutorial.
This example will request an SSL certificate for example.com
domain
module "acm_request_certificate" {
source = "cloudposse/acm-request-certificate/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
domain_name = "example.com"
process_domain_validation_options = true
ttl = "300"
}
This example will request an SSL certificate for example.com
domain and all its subdomains *.example.com
module "acm_request_certificate" {
source = "cloudposse/acm-request-certificate/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
domain_name = "example.com"
process_domain_validation_options = true
ttl = "300"
subject_alternative_names = ["*.example.com"]
}
Important
In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Name | Description | Type | Default | Required |
---|---|---|---|---|
additional_tag_map | Additional key-value pairs to add to each map in tags_as_list_of_maps . Not added to tags or id .This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration. |
map(string) |
{} |
no |
attributes | ID element. Additional attributes (e.g. workers or cluster ) to add to id ,in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element. |
list(string) |
[] |
no |
certificate_authority_arn | ARN of an ACM PCA | string |
null |
no |
certificate_transparency_logging_preference | Specifies whether certificate details should be added to a certificate transparency log | bool |
true |
no |
context | Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value.Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged. |
any |
{ |
no |
delimiter | Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all. |
string |
null |
no |
descriptor_formats | Describe additional descriptors to be output in the descriptors output map.Map of maps. Keys are names of descriptors. Values are maps of the form {<br> format = string<br> labels = list(string)<br>} (Type is any so the map values can later be enhanced to provide additional options.)format is a Terraform format string to be passed to the format() function.labels is a list of labels, in order, to pass to format() function.Label values will be normalized before being passed to format() so they will beidentical to how they appear in id .Default is {} (descriptors output will be empty). |
any |
{} |
no |
domain_name | A domain name for which the certificate should be issued | string |
n/a | yes |
enabled | Set to false to prevent the module from creating any resources | bool |
null |

environment | ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT' | string |
null |
no |
id_length_limit | Limit id to this many characters (minimum 6).Set to 0 for unlimited length.Set to null for keep the existing setting, which defaults to 0 .Does not affect id_full . |
number |
null |
no |
key_algorithm | Specifies the algorithm of the public and private key pair that your Amazon issued certificate uses to encrypt data | string |
null |
no |
label_key_case | Controls the letter case of the tags keys (label names) for tags generated by this module.Does not affect keys of tags passed in via the tags input.Possible values: lower , title , upper .Default value: title . |
string |
null |
no |
label_order | The order in which the labels (ID elements) appear in the id .Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present. |
list(string) |
null |
no |
label_value_case | Controls the letter case of ID elements (labels) as included in id ,set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input.Possible values: lower , title , upper and none (no transformation).Set this to title and set delimiter to "" to yield Pascal Case IDs.Default value: lower . |
string |
null |
no |
labels_as_tags | Set of labels (ID elements) to include as tags in the tags output.Default is to include all labels. Tags with empty values will not be included in the tags output.Set to [] to suppress all generated tags.Notes: The value of the name tag, if included, will be the id , not the name .Unlike other null-label inputs, the initial setting of labels_as_tags cannot bechanged in later chained modules. Attempts to change it will be silently ignored. |
set(string) |
[ |
no |
name | ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a tag .The "name" tag is set to the full id string. There is no tag with the value of the name input. |

{} |
no |
