AWS CloudFront Terraform module

Terraform module which creates AWS CloudFront resources with all (or almost all) features provided by Terraform AWS provider.

These types of resources supported:

Terraform versions

Only Terraform 0.13 or newer is supported.

Inputs

Name	Description	Type	Default	Required
aliases	Extra CNAMEs (alternate domain names), if any, for this distribution.	`list(string)`	`null`	no
comment	Any comments you want to include about the distribution.	`string`	`null`	no
create_distribution	Controls if CloudFront distribution should be created	`bool`	`true`	no
create_origin_access_identity	Controls if CloudFront origin access identity should be created	`bool`	`false`	no
custom_error_response	One or more custom error response elements	`any`	`{}`	no
default_cache_behavior	The default cache behavior for this distribution	`any`	`null`	no
default_root_object	The object that you want CloudFront to return (for example, index.html) when an end user requests the root URL.	`string`	`null`	no
enabled	Whether the distribution is enabled to accept end user requests for content.	`bool`	`true`	no
geo_restriction	The restriction configuration for this distribution (geo_restrictions)	`any`	`{}`	no

logging_config	The logging configuration that controls how logs are written to your distribution (maximum one).	`any`	`{}`	no
ordered_cache_behavior	An ordered list of cache behaviors resource for this distribution. List from top to bottom in order of precedence. The topmost cache behavior will have precedence 0.	`any`	`[]`	no
