This module is written in Terraform 0.12 to create Cloudfront distributiions using multiple origins (S3 or ALB) and dynamic behaviour

• environment: Optional. To create an cloudfront name and using in the locals origin_id
• app_name: Optional. To create an cloudfront name and using in the locals origin_id
• role: Optional. To create an cloudfront name and using in the locals origin_id
• enable: Mandatory. Boolean to enable the Cloudfront distribution or not. Defaults true
• is_ipv6_enabled: Optional. Boolean to enable IPv6. Defaults true
• comment: Optional. Description of your comment for your CloudFront
• default_root_object: Optional. Root index object. Defaults empty
• aliases: Optional. Extra CNAMEs (alternate domain names), if any, for this distribution.
• restriction_type: Mandatory for geo_restrictions. Defaults to none
• locations: Mandatory if a geo_restriction is not set to none. Country codes: ISO 3166-1-alpha-2 codes
• price_class: Optional. The price class for this distribution. Defaults to PriceClass_200
• cloudfront_default_certificate: Mandatory. if you want viewers to use HTTPS to request your objects and you're using the CloudFront domain name for your distribution
• cloudfront_logging_enabled: Optional. If set to true, a bucket must to be set. See logging_config. Defaults to false
• s3_origin_configs: Mandatory. At least one origin must to be specified between s3_origin_configs or custom_origin_configs
• custom_origin_configs: Mandatory. At least one origin must to be specified between s3_origin_configs or custom_origin_configs
• default_cache_behavior: Mandatory. Default values has been set on variables.tf
• ordered_cache_behavior_variables: Mandatory. Default values has been set on variables.tf
• waf_web_acl_id: Optional. If provided it will be used and attached to distribution
• acm_certificate_arn_config: Optional. If nothing is specified it goes to the default certificate. Viewer Certificate Arguments
• tags: Optional. Tags added to cloudfront distribution
