This helps bypass [validation checks](https://github.com/hashicorp/terraform/issues/21408) that want the `provider` blocks within this module to have a `region` attribute specified. 10 | 11 | ```hcl 12 | provider "aws" { 13 | region = "us-east-1" 14 | alias = "certificates" 15 | } 16 | 17 | provider "aws" { 18 | region = "us-west-2" 19 | alias = "dns" 20 | } 21 | 22 | resource "aws_route53_zone" "default" { 23 | name = "azavea.com" 24 | } 25 | 26 | module "cert" { 27 | source = "github.com/azavea/terraform-aws-acm-certificate" 28 | 29 | providers = { 30 | aws.acm_account = "aws.certificates" 31 | aws.route53_account = "aws.dns" 32 | } 33 | 34 | domain_name = "azavea.com" 35 | subject_alternative_names = ["*.azavea.com"] 36 | hosted_zone_id = "${aws_route53_zone.default.zone_id}" 37 | validation_record_ttl = "60" 38 | allow_validation_record_overwrite = true 39 | } 40 | ``` 41 | 42 | ## Variables 43 | 44 | - `domain_name` - Primary domain name associated with certificate. Also used for the Name tag of the ACM certificate. 45 | - `subject_alternative_names` - Subject alternative domain names. 46 | - `hosted_zone_id` - Route 53 hosted zone ID for `domain_name`. 47 | - `validation_record_ttl` - Route 53 record time-to-live (TTL) for validation record (default: `60`). 48 | - `allow_validation_record_overwrite` - Allow Route 53 record creation to overwrite existing records (default: `true`). 49 | - `tags` - A map of extra tags that is associated with the ACM Certificate. 50 | 51 | ## Outputs 52 | 53 | - `arn` - The Amazon Resource Name (ARN) of the ACM certificate 54 | -------------------------------------------------------------------------------- /main.tf: -------------------------------------------------------------------------------- 1 | resource "aws_acm_certificate" "default" { 2 | provider = aws.acm_account 3 | domain_name = var.domain_name 4 | subject_alternative_names = var.subject_alternative_names 5 | validation_method = "DNS" 6 | 7 | lifecycle { 8 | create_before_destroy = true 9 | } 10 | 11 | tags = merge( 12 | { 13 | Name = var.domain_name 14 | }, 15 | var.tags, 16 | ) 17 | } 18 | 19 | resource "aws_route53_record" "validation" { 20 | provider = aws.route53_account 21 | for_each = { 22 | for dvo in aws_acm_certificate.default.domain_validation_options : dvo.domain_name => { 23 | name = dvo.resource_record_name 24 | record = dvo.resource_record_value 25 | type = dvo.resource_record_type 26 | } 27 | } 28 | 29 | name = each.value.name 30 | type = each.value.type 31 | zone_id = var.hosted_zone_id 32 | records = [each.value.record] 33 | ttl = var.validation_record_ttl 34 | allow_overwrite = var.allow_validation_record_overwrite 35 | } 36 | 37 | resource "aws_acm_certificate_validation" "default" { 38 | provider = aws.acm_account 39 | certificate_arn = aws_acm_certificate.default.arn 40 | 41 | validation_record_fqdns = [for record in aws_route53_record.validation : record.fqdn] 42 | } 43 | -------------------------------------------------------------------------------- /outputs.tf: -------------------------------------------------------------------------------- 1 | output "arn" { 2 | value = aws_acm_certificate_validation.default.certificate_arn 3 | } 4 | -------------------------------------------------------------------------------- /scripts/cibuild: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | set -e 4 | 5 | if [[ -n "${CI_DEBUG}" ]]; then 6 | set -x 7 | fi 8 | 9 | function usage() { 10 | echo -n \ 11 | "Usage: $(basename "$0") 12 | Ensure the Terraform source code is properly formatted. 13 | " 14 | } 15 | 16 | if [ "${BASH_SOURCE[0]}" = "${0}" ]; then 17 | if [ "${1:-}" = "--help" ]; then 18 | usage 19 | else 20 | terraform fmt -check 21 | fi 22 | fi 23 | -------------------------------------------------------------------------------- /variables.tf: -------------------------------------------------------------------------------- 1 | variable "domain_name" { 2 | type = string 3 | description = "Primary certificate domain name" 4 | } 5 | 6 | variable "subject_alternative_names" { 7 | default = [] 8 | type = list(string) 9 | description = "Subject alternative domain names" 10 | } 11 | 12 | variable "hosted_zone_id" { 13 | type = string 14 | description = "Route 53 Zone ID for DNS validation records" 15 | } 16 | 17 | variable "validation_record_ttl" { 18 | default = 60 19 | type = number 20 | description = "Route 53 time-to-live for validation records" 21 | } 22 | 23 | variable "allow_validation_record_overwrite" { 24 | default = true 25 | type = bool 26 | description = "Allow Route 53 record creation to overwrite existing records" 27 | } 28 | 29 | variable "tags" { 30 | default = {} 31 | type = map(string) 32 | description = "Extra tags to attach to the ACM certificate" 33 | } 34 | 35 | -------------------------------------------------------------------------------- /versions.tf: -------------------------------------------------------------------------------- 1 | terraform { 2 | required_version = ">= 0.15" 3 | required_providers { 4 | aws = { 5 | version = ">= 3.0.0" 6 | configuration_aliases = [aws.acm_account, aws.route53_account] 7 | } 8 | } 9 | } 10 | --------------------------------------------------------------------------------
