--- layout: "aws" page_title: "AWS: cloudfront_distribution" sidebar_current: "docs-aws-resource-cloudfront-distribution" description: |- Provides a CloudFront web distribution resource. --- # aws\_cloudfront\_distribution Creates an Amazon CloudFront web distribution. For information about CloudFront distributions, see the [Amazon CloudFront Developer Guide][1]. For specific information about creating CloudFront web distributions, see the [POST Distribution][2] page in the Amazon CloudFront API Reference. ~> **NOTE:** CloudFront distributions take about 15 minutes to a deployed state after creation or modification. During this time, deletes to resources will be blocked. If you need to delete a distribution that is enabled and you do not want to wait, you need to use the `retain_on_delete` flag. ## Example Usage The following example below creates a CloudFront distribution with an S3 origin. ``` resource "aws_s3_bucket" "b" { bucket = "mybucket" acl = "private" tags { Name = "My bucket" } } resource "aws_cloudfront_distribution" "s3_distribution" { origin { domain_name = "${aws_s3_bucket.b.bucket}.s3.amazonaws.com" origin_id = "myS3Origin" s3_origin_config { origin_access_identity = "origin-access-identity/cloudfront/ABCDEFG1234567" } } enabled = true is_ipv6_enabled = true comment = "Some comment" default_root_object = "index.html" logging_config { include_cookies = false bucket = "mylogs.s3.amazonaws.com" prefix = "myprefix" } aliases = ["mysite.example.com", "yoursite.example.com"] default_cache_behavior { allowed_methods = ["DELETE", "GET", "HEAD", "OPTIONS", "PATCH", "POST", "PUT"] cached_methods = ["GET", "HEAD"] target_origin_id = "myS3Origin" forwarded_values { query_string = false cookies { forward = "none" } } viewer_protocol_policy = "allow-all" min_ttl = 0 default_ttl = 3600 max_ttl = 86400 } price_class = "PriceClass_200" restrictions { geo_restriction { restriction_type = "whitelist" locations = ["US", "CA", "GB", "DE"] } } tags { Environment = "production" } viewer_certificate { cloudfront_default_certificate = true } } ``` ## Argument Reference The CloudFront distribution argument layout is a complex structure composed of several sub-resources - these resources are laid out below. ### Top-Level Arguments * `aliases` (Optional) - Extra CNAMEs (alternate domain names), if any, for this distribution. * `cache_behavior` (Optional) - A [cache behavior](#cache-behavior-arguments) resource for this distribution (multiples allowed). * `comment` (Optional) - Any comments you want to include about the distribution. * `custom_error_response` (Optional) - One or more [custom error response](#custom-error-response-arguments) elements (multiples allowed). * `default_cache_behavior` (Required) - The [default cache behavior](#default-cache-behavior-arguments) for this distribution (maximum one). * `default_root_object` (Optional) - The object that you want CloudFront to return (for example, index.html) when an end user requests the root URL. * `enabled` (Required) - Whether the distribution is enabled to accept end user requests for content. * `is_ipv6_enabled` (Optional) - Whether the IPv6 is enabled for the distribution. * `http_version` (Optional) - The maximum HTTP version to support on the distribution.
