Properties

Aliases

CNAMEs (alternate domain names), if any, for the distribution.

Required: No

Type: List of String values

CacheBehaviors

A list of CacheBehavior types for the distribution.

Required: No

Type: List of CacheBehavior

Comment

Any comments that you want to include about the distribution. Optional.

When you create a distribution, you can include a comment of up to 128 characters. You can update the comment at any time.

Required: No

Type: String

CustomErrorResponses

Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.

Required: No

Type List of CloudFront DistributionConfig CustomErrorResponse

DefaultCacheBehavior

The default cache behavior that is triggered if you do not specify the CacheBehavior property or if files don't match any of the values of PathPattern in the CacheBehavior property.

Required: Yes

Type: DefaultCacheBehavior type

DefaultRootObject

The object (such as index.html) that you want CloudFront to request from your origin when the root URL for your distribution (such as http://example.com/) is requested.

Note

Specifying a default root object avoids exposing the contents of your distribution.

Required: No

Type: String

Enabled

Controls whether the distribution is enabled to accept end user requests for content.

Required: Yes

Type: Boolean

HttpVersion

The latest HTTP version that viewers can use to communicate with CloudFront. Viewers that don't support the latest version automatically use an earlier HTTP version. By default, AWS CloudFormation specifies http1.1.

For valid values, see the HttpVersion content for the DistributionConfig data type in the Amazon CloudFront API Reference.

Required: No

Type: String

IPV6Enabled

If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution. For more information and usage guidance, see CreateDistribution in the Amazon CloudFront API Reference.

Required: No

Type: Boolean

Update requires: No interruption

Logging

Controls whether access logs are written for the distribution. To turn on access logs, specify this property.

Required: No

Type: Logging type

Origins

A list of origins for this CloudFront distribution. For each origin, you can specify whether it is an Amazon S3 or custom origin.

Required: Yes

Type: List of Origins.

PriceClass

The price class that corresponds with the maximum price that you want to pay for the CloudFront service. For more information, see Choosing the Price Class in the Amazon CloudFront Developer Guide.

For more information about the valid values, see the PriceClass content for the DistributionConfig data type in the Amazon CloudFront API Reference.

Required: No

Type: String

Restrictions

Specifies restrictions on who or how viewers can access your content.

Required: No

Type: CloudFront DistributionConfiguration Restrictions

ViewerCertificate

The certificate to use when viewers use HTTPS to request objects.

Required: No

Type: CloudFront DistributionConfiguration ViewerCertificate

WebACLId

The AWS WAF web ACL to associate with this distribution. AWS WAF is a web application firewall that enables you to monitor the HTTP and HTTPS requests that are forwarded to CloudFront and to control who can access your content. CloudFront permits or forbids requests based on conditions that you specify, such as the IP addresses from which requests originate or the values of query strings.

Required: No

Type: String
