Associates an alias (also known as a CNAME or an alternate domain name) with a CloudFront distribution.

With this operation you can move an alias that's already in use on a CloudFront distribution to a different distribution in one step. This prevents the downtime that could occur if you first remove the alias from one distribution and then separately add the alias to another distribution.

To use this operation to associate an alias with a distribution, you provide the alias and the ID of the target distribution for the alias. For more information, including how to set up the target distribution, prerequisites that you must complete, and other restrictions, see Moving an alternate domain name to a different distribution in the Amazon CloudFront Developer Guide.

Creates a staging distribution using the configuration of the provided primary distribution.

A staging distribution is a copy of an existing distribution (called the primary distribution) that you can use in a continuous deployment workflow.

After you create a staging distribution, you can use UpdateDistribution to modify the staging distribution's configuration. Then you can use CreateContinuousDeploymentPolicy to incrementally move traffic to the staging distribution.

This API operation requires the following IAM permissions:

*

GetDistribution

*

CreateDistribution

*

CopyDistribution

Creates a cache policy.

After you create a cache policy, you can attach it to one or more cache behaviors. When it's attached to a cache behavior, the cache policy determines the following:

The values that CloudFront includes in the cache key*. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.

* The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.

The headers, cookies, and query strings that are included in the cache key are also included in requests that CloudFront sends to the origin. CloudFront sends a request when it can't find an object in its cache that matches the request's cache key. If you want to send values to the origin but not include them in the cache key, use OriginRequestPolicy.

For more information about cache policies, see Controlling the cache key in the Amazon CloudFront Developer Guide.

Creates a new origin access identity.

If you're using Amazon S3 for your origin, you can use an origin access identity to require users to access your content using a CloudFront URL instead of the Amazon S3 URL. For more information about how to use origin access identities, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.

Creates a continuous deployment policy that distributes traffic for a custom domain name to two different CloudFront distributions.

To use a continuous deployment policy, first use CopyDistribution to create a staging distribution, then use UpdateDistribution to modify the staging distribution's configuration.

After you create and update a staging distribution, you can use a continuous deployment policy to incrementally move traffic to the staging distribution. This workflow enables you to test changes to a distribution's configuration before moving all of your domain's production traffic to the new configuration.

Creates a CloudFront distribution.

Create a new distribution with tags.

This API operation requires the following IAM permissions:

*

CreateDistribution

*

TagResource

Create a new field-level encryption configuration.

Create a field-level encryption profile.

Creates a CloudFront function.

To create a function, you provide the function code and some configuration information about the function. The response contains an Amazon Resource Name (ARN) that uniquely identifies the function.

When you create a function, it's in the DEVELOPMENT stage. In this stage, you can test the function with TestFunction, and update it with UpdateFunction.

When you're ready to use your function with a CloudFront distribution, use PublishFunction to copy the function from the DEVELOPMENT stage to LIVE. When it's live, you can attach the function to a distribution's cache behavior, using the function's ARN.

Create a new invalidation.

For more information, see Invalidating files in the Amazon CloudFront Developer Guide.

Creates a key group that you can use with CloudFront signed URLs and signed cookies.

To create a key group, you must specify at least one public key for the key group. After you create a key group, you can reference it from one or more cache behaviors. When you reference a key group in a cache behavior, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with a private key whose corresponding public key is in the key group. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see Serving private content in the Amazon CloudFront Developer Guide.

Specifies the key value store resource to add to your account.

In your account, the key value store names must be unique. You can also import key value store data in JSON format from an S3 bucket by providing a valid ImportSource that you own.

Enables additional CloudWatch metrics for the specified CloudFront distribution.

The additional metrics incur an additional cost.

For more information, see Viewing additional CloudFront distribution metrics in the Amazon CloudFront Developer Guide.

Creates a new origin access control in CloudFront.

After you create an origin access control, you can add it to an origin in a CloudFront distribution so that CloudFront sends authenticated (signed) requests to the origin.

This makes it possible to block public access to the origin, allowing viewers (users) to access the origin's content only through CloudFront.

For more information about using a CloudFront origin access control, see Restricting access to an Amazon Web Services origin in the Amazon CloudFront Developer Guide.

Creates an origin request policy.

After you create an origin request policy, you can attach it to one or more cache behaviors. When it's attached to a cache behavior, the origin request policy determines the values that CloudFront includes in requests that it sends to the origin. Each request that CloudFront sends to the origin includes the following:

* The request body and the URL path (without the domain name) from the viewer request.

* The headers that CloudFront automatically includes in every origin request, including Host, User-Agent, and X-Amz-Cf-Id.

* All HTTP headers, cookies, and URL query strings that are specified in the cache policy or the origin request policy. These can include items from the viewer request and, in the case of headers, additional ones that are added by CloudFront.

CloudFront sends a request when it can't find a valid object in its cache that matches the request. If you want to send values to the origin and also include them in the cache key, use CachePolicy.

For more information about origin request policies, see Controlling origin requests in the Amazon CloudFront Developer Guide.

Uploads a public key to CloudFront that you can use with signed URLs and signed cookies, or with field-level encryption.

Creates a real-time log configuration.

After you create a real-time log configuration, you can attach it to one or more cache behaviors to send real-time log data to the specified Amazon Kinesis data stream.

For more information about real-time log configurations, see Real-time logs in the Amazon CloudFront Developer Guide.

Creates a response headers policy.

A response headers policy contains information about a set of HTTP headers. To create a response headers policy, you provide some metadata about the policy and a set of configurations that specify the headers.

After you create a response headers policy, you can use its ID to attach it to one or more cache behaviors in a CloudFront distribution. When it's attached to a cache behavior, the response headers policy affects the HTTP headers that CloudFront includes in HTTP responses to requests that match the cache behavior. CloudFront adds or removes response headers according to the configuration of the response headers policy.

For more information, see Adding or removing HTTP headers in CloudFront responses in the Amazon CloudFront Developer Guide.

This API is deprecated.

List tags for a CloudFront resource.

Publishes a CloudFront function by copying the function code from the DEVELOPMENT stage to LIVE.

This automatically updates all cache behaviors that are using this function to use the newly published copy in the LIVE stage.

When a function is published to the LIVE stage, you can attach the function to a distribution's cache behavior, using the function's Amazon Resource Name (ARN).

To publish a function, you must provide the function's name and version (ETag value). To get these values, you can use ListFunctions and DescribeFunction.

Add tags to a CloudFront resource.

Tests a CloudFront function.

To test a function, you provide an event object that represents an HTTP request or response that your CloudFront distribution could receive in production. CloudFront runs the function, passing it the event object that you provided, and returns the function's result (the modified event object) in the response. The response also contains function logs and error messages, if any exist. For more information about testing functions, see Testing functions in the Amazon CloudFront Developer Guide.

To test a function, you provide the function's name and version (ETag value) along with the event object. To get the function's name and version, you can use ListFunctions and DescribeFunction.

Remove tags from a CloudFront resource.

Updates a cache policy configuration.

When you update a cache policy configuration, all the fields are updated with the values provided in the request. You cannot update some fields independent of others. To update a cache policy configuration:

1. Use GetCachePolicyConfig to get the current configuration.

2. Update the distribution configuration that was returned in the response. Note the following important requirements and restrictions:

*

You must rename the ETag field to IfMatch, leaving the value unchanged. (Set the value of IfMatch to the value of ETag, then remove the ETag field.)

*

You can't change the value of CallerReference.

3. Submit an UpdateDistribution request, providing the distribution configuration. The new configuration replaces the existing configuration. The values that you specify in an UpdateDistribution request are not merged into your existing configuration. Make sure to include all fields: the ones that you modified and also the ones that you didn't.

Copies the staging distribution's configuration to its corresponding primary distribution.

The primary distribution retains its Aliases (also known as alternate domain names or CNAMEs) and ContinuousDeploymentPolicyId value, but otherwise its configuration is overwritten to match the staging distribution.

You can use this operation in a continuous deployment workflow after you have tested configuration changes on the staging distribution. After using a continuous deployment policy to move a portion of your domain name's traffic to the staging distribution and verifying that it works as intended, you can use this operation to copy the staging distribution's configuration to the primary distribution. This action will disable the continuous deployment policy and move your domain's traffic back to the primary distribution.
