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_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.
* `cache_behavior` (Optional) - A [cache behavior](#cache_behavior) 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) elements (multiples allowed).
* `default_cache_behavior` (Required) - The [default cache behavior](#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](#logging_config) that controls how logs are written to your distribution (maximum one).
* `origin` (Required) - One or more [origins](#origin) for this distribution (multiples allowed).

* `viewer_certificate` (Required) - The [SSL configuration](#viewer_certificate) for this 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`.
#### <a name="cache_behavior"> `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](#forwarded_values) that specifies how CloudFront handles query strings, cookies and headers (maximum one).

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`.

* `whitelisted_names` (Optional) - If you have specified `whitelist` to `forward`, the whitelisted cookies that you want CloudFront to forward to your origin.
#### <a name="custom_error_response"> `custom_error_response` Arguments

* `error_code` (Required) - The 4xx or 5xx HTTP status code that you want to customize.
* `response_code` (Optional) - The HTTP status code that you want CloudFront to return with the custom error page to the viewer.
* `response_page_path` (Optional) - The path of the custom error page (for example, `/custom_404.html`).

* `ssl_support_method`: Specifies how you want CloudFront to serve HTTPS requests. One of `vip` or `sni-only`. Required if you specify `acm_certificate_arn` or `iam_certificate_id`. **NOTE:** `vip` causes CloudFront to use a dedicated IP address and may incur extra charges.
