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.
```hcl
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_domain_name}"
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

configuration](#logging-config-arguments) that controls how logs are written
to your distribution (maximum one).
* `origin` (Required) - One or more [origins](#origin-arguments) for this
distribution (multiples allowed).

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

compress content for web requests that include `Accept-Encoding: gzip` in
the request header (default: `false`).

object is in a CloudFront cache before CloudFront forwards another request
in the absence of an `Cache-Control max-age` or `Expires` header.

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.

* `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

* `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.
##### Lambda Function Association
Lambda@Edge allows you to associate an AWS Lambda Function with a predefined
event. You can associate a single function per event type. See [What is
Lambda@Edge](http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/what-is-lambda-at-edge.html)

[`cache_behavior`](#cache-behavior-arguments), except for the `path_pattern`
argument is not required.
#### Logging Config Arguments
* `bucket` (Required) - The Amazon S3 bucket to store the access logs in, for

* `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

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.
