aws	AWS: cloudfront_distribution	docs-aws-resource-cloudfront-distribution	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. For specific information about creating CloudFront web distributions, see the POST Distribution 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_cloudfront_distribution" "s3_distribution" {
  origin {
    domain_name = "mybucket.s3.amazonaws.com"
    origin_id   = "myS3Origin"

    s3_origin_config {
      origin_access_identity = "origin-access-identity/cloudfront/ABCDEFG1234567"
    }
  }

  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"]
    }
  }

  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.

default_cache_behavior (Required) - The default cache behavior 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.
logging_config (Optional) - The logging configuration that controls how logs are written to your distribution (maximum one).

web_acl_id (Optional) - If you're using AWS WAF to filter CloudFront requests, the Id of the AWS WAF web ACL that is associated with the distribution.
retain_on_delete (Optional) - Disables the distribution instead of deleting it when destroying the resource through Terraform. If this is set, the distribution needs to be deleted manually afterwards. Default: false.

`cache_behavior` Arguments

allowed_methods (Required) - Controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin.

cached_methods (Required) - Controls whether CloudFront caches the response to requests using the specified HTTP methods.

compress (Optional) - Whether you want CloudFront to automatically compress content for web requests that include Accept-Encoding: gzip in the request header (default: false).

default_ttl (Required) - The default amount of time (in seconds) that an object is in a CloudFront cache before CloudFront forwards another request in the absence of an Cache-Control max-age or Expires header.

forwarded_values (Required) - The forwarded values configuration that specifies how CloudFront handles query strings, cookies and headers (maximum one).
max_ttl (Required) - The maximum amount of time (in seconds) that an object is in a CloudFront cache before CloudFront forwards another request to your origin to determine whether the object has been updated. Only effective in the presence of Cache-Control max-age, Cache-Control s-maxage, and Expires headers.
min_ttl (Required) - The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront queries your origin to see whether the object has been updated.
path_pattern (Required) - The pattern (for example, images/*.jpg) that specifies which requests you want this cache behavior to apply to.
smooth_streaming (Optional) - Indicates whether you want to distribute media files in Microsoft Smooth Streaming format using the origin that is associated with this cache behavior.
target_origin_id (Required) - The value of ID for the origin that you want CloudFront to route requests to when a request matches the path pattern either for a cache behavior or for the default cache behavior.
trusted_signers (Optional) - The AWS accounts, if any, that you want to allow to create signed URLs for private content.
viewer_protocol_policy (Required) - Use this element to specify the protocol that users can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. One of allow-all, https-only, or redirect-to-https.

`forwarded_values` Arguments

cookies (Optional) - The forwarded values cookies that specifies how CloudFront handles cookies (maximum one).
headers (Optional) - Specifies the Headers, if any, that you want CloudFront to vary upon for this cache behavior. Specify * to include all headers.

restriction_type (Required) - The method that you want to use to restrict distribution of your content by country: none, whitelist, or blacklist.

`viewer_certificate` Arguments

acm_certificate_arn - The ARN of the AWS Certificate Manager certificate that you wish to use with this distribution. Specify this, cloudfront_default_certificate, or iam_certificate_id.
cloudfront_default_certificate - true if you want viewers to use HTTPS to request your objects and you're using the CloudFront domain name for your distribution. Specify this, acm_certificate_arn, or iam_certificate_id.
