  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"]
    }
  }

  tags {
    Environment = "production"
  }

  viewer_certificate {
    cloudfront_default_certificate = true
  }
}
```

The CloudFront distribution argument layout is a complex structure composed
of several sub-resources - these resources are laid out below.

    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](#forwarded-values-arguments) 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

    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

    query strings to the origin that is associated with this cache behavior.

  * `query_string_cache_keys` (Optional) - When specified, along with a value of
    `true` for `query_string`, all query strings are forwarded, however only the
    query string keys listed in this argument are cached. When omitted with a
    value of `true` for `query_string`, all query string keys are cached.

##### Cookies Arguments

  * `forward` (Required) - Specifies whether you want CloudFront to forward
    cookies to the origin that is associated with this cache behavior. You can

    to the access log filenames for this distribution, for example, `myprefix/`.

#### Origin Arguments

  * `custom_origin_config` - The [CloudFront custom
    origin](#custom-origin-config-arguments) configuration information. If an S3
    origin is required, use `s3_origin_config` instead.

    web site of your custom origin.

  * `custom_header` (Optional) - One or more sub-resources with `name` and

##### S3 Origin Config Arguments

* `origin_access_identity` (Optional) - The [CloudFront origin access
  identity][5] to associate with the origin.

#### Restrictions Arguments

The `restrictions` sub-resource takes another single sub-resource named
`geo_restriction` (see the example for usage).

The arguments of `geo_restriction` are:

  * `locations` (Optional) - The [ISO 3166-1-alpha-2 codes][4] for which you
    want CloudFront either to distribute your content (`whitelist`) or not
    distribute your content (`blacklist`).

  * `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][6]
    certificate that you wish to use with this distribution. Specify this,
    `cloudfront_default_certificate`, or `iam_certificate_id`.  The ACM
    certificate must be in  US-EAST-1.

  * `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`.

  * `iam_certificate_id` - The IAM certificate identifier of the custom viewer
    certificate for this distribution if you are using a custom domain. Specify
    this, `acm_certificate_arn`, or `cloudfront_default_certificate`.

  * `minimum_protocol_version` - The minimum version of the SSL protocol that
    you want CloudFront to use for HTTPS connections. One of `SSLv3` or `TLSv1`.
    Default: `SSLv3`. **NOTE**: If you are using a custom certificate (specified
    with `acm_certificate_arn` or `iam_certificate_id`), and have specified
    `sni-only` in `ssl_support_method`, `TLSv1` must be specified.

  * `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.

## Attribute Reference
