list-distributions-by-realtime-log-config

Description

Gets a list of distributions that have a cache behavior that’s associated with the specified real-time log configuration.

You can specify the real-time log configuration by its name or its Amazon Resource Name (ARN). You must provide at least one. If you provide both, CloudFront uses the name to identify the real-time log configuration to list distributions for.

You can optionally specify the maximum number of items to receive in the response. If the total number of items in the list exceeds the maximum that you specify, or the default maximum, the response is paginated. To get the next page of items, send a subsequent request that specifies the NextMarker value from the current response as the Marker value in the subsequent request.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  list-distributions-by-realtime-log-config
[--marker <value>]
[--max-items <value>]
[--realtime-log-config-name <value>]
[--realtime-log-config-arn <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--marker (string)

Use this field when paginating results to indicate where to begin in your list of distributions. The response includes distributions in the list that occur after the marker. To get the next page of the list, set this field’s value to the value of NextMarker from the current page’s response.

--max-items (string)

The maximum number of distributions that you want in the response.

--realtime-log-config-name (string)

The name of the real-time log configuration whose associated distributions you want to list.

--realtime-log-config-arn (string)

The Amazon Resource Name (ARN) of the real-time log configuration whose associated distributions you want to list.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

S3OriginConfig -> (structure)

Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.

OriginAccessIdentity -> (string)

The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:

origin-access-identity/cloudfront/ID-of-origin-access-identity

where `` ID-of-origin-access-identity `` is the value that CloudFront returned in the ID element when you created the origin access identity.

If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.

To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.

To replace the origin access identity, update the distribution configuration and specify the new origin access identity.

For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide .

CustomOriginConfig -> (structure)

Use this type to specify an origin that is not an Amazon S3 bucket, with one exception. If the Amazon S3 bucket is configured with static website hosting, use this type. If the Amazon S3 bucket is not configured with static website hosting, use the S3OriginConfig type instead.

TargetOriginId -> (string)

The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.

TrustedSigners -> (structure)

Warning

We recommend using TrustedKeyGroups instead of TrustedSigners .

A list of Amazon Web Services account IDs whose public keys CloudFront can use to validate signed URLs or signed cookies.

When a cache behavior contains trusted signers, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with the private key of a CloudFront key pair in a trusted signer’s Amazon Web Services account. 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 .

Enabled -> (boolean)

This field is true if any of the Amazon Web Services accounts have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field is false .

Quantity -> (integer)

The number of Amazon Web Services accounts in the list.

Items -> (list)

A list of Amazon Web Services account identifiers.

(string)

TrustedKeyGroups -> (structure)

A list of key groups that CloudFront can use to validate signed URLs or signed cookies.

When a cache behavior contains trusted key groups, 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 .

This field is true if any of the key groups in the list have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field is false .

Quantity -> (integer)

The number of key groups in the list.

Items -> (list)

A list of key groups identifiers.

(string)

ViewerProtocolPolicy -> (string)

The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern . You can specify the following options:

  • allow-all : Viewers can use HTTP or HTTPS.

  • redirect-to-https : If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.

  • https-only : If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).

For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide .

Note

The only way to guarantee that viewers retrieve an object that was fetched from the origin using HTTPS is never to use any other protocol to fetch the object. If you have recently changed from HTTP to HTTPS, we recommend that you clear your objects’ cache because cached objects are protocol agnostic. That means that an edge location will return an object from the cache regardless of whether the current request protocol matches the protocol used previously. For more information, see Managing Cache Expiration in the Amazon CloudFront Developer Guide .

AllowedMethods -> (structure)

A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:

  • CloudFront forwards only GET and HEAD requests.

  • CloudFront forwards only GET , HEAD , and OPTIONS requests.

  • CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST , and DELETE requests.

If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can’t perform operations that you don’t want them to. For example, you might not want users to have permissions to delete objects from your origin.

Quantity -> (integer)

The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET , HEAD , and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST , and DELETE requests).

Items -> (list)

A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.

(string)

CachedMethods -> (structure)

A complex type that controls whether CloudFront caches the response to requests using the specified HTTP methods. There are two choices:

  • CloudFront caches responses to GET and HEAD requests.

  • CloudFront caches responses to GET , HEAD , and OPTIONS requests.

If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.

Quantity -> (integer)

The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET , HEAD , and OPTIONS requests).

Items -> (list)

A complex type that contains the HTTP methods that you want CloudFront to cache responses to.

(string)

SmoothStreaming -> (boolean)

Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true ; if not, specify false . If you specify true for SmoothStreaming , you can still distribute other content using this cache behavior if the content matches the value of PathPattern .

Compress -> (boolean)

Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true ; if not, specify false . For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide .

A complex type that contains zero or more Lambda@Edge function associations for a cache behavior.

Quantity -> (integer)

The number of Lambda@Edge function associations for this cache behavior.

Items -> (list)

Optional : A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0 , you can omit Items .

A complex type that contains a Lambda@Edge function association.

LambdaFunctionARN -> (string)

The ARN of the Lambda@Edge function. You must specify the ARN of a function version; you can’t specify an alias or $LATEST.

EventType -> (string)

Specifies the event type that triggers a Lambda@Edge function invocation. You can specify the following values:

  • viewer-request : The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.

  • origin-request : The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn’t execute.

  • origin-response : The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn’t execute.

  • viewer-response : The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn’t execute.

IncludeBody -> (boolean)

A flag that allows a Lambda@Edge function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.

FunctionAssociations -> (structure)

RealtimeLogConfigArn -> (string)

The Amazon Resource Name (ARN) of the real-time log configuration that is attached to this cache behavior. For more information, see Real-time logs in the Amazon CloudFront Developer Guide .

CachePolicyId -> (string)

The unique identifier of the cache policy that is attached to the default cache behavior. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide .

A DefaultCacheBehavior must include either a CachePolicyId or ForwardedValues . We recommend that you use a CachePolicyId .

OriginRequestPolicyId -> (string)

The unique identifier of the origin request policy that is attached to the default cache behavior. For more information, see Creating origin request policies or Using the managed origin request policies in the Amazon CloudFront Developer Guide .

ResponseHeadersPolicyId -> (string)

The identifier for a response headers policy.

ForwardedValues -> (structure)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field. For more information, see Working with policies in the Amazon CloudFront Developer Guide .

If you want to include values in the cache key, use a cache policy. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide .

A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.

QueryString -> (boolean)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include query strings in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send query strings to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys , if any:

If you specify true for QueryString and you don’t specify any values for QueryStringCacheKeys , CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.

If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys , CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.

If you specify false for QueryString , CloudFront doesn’t forward any query string parameters to the origin, and doesn’t cache based on query string parameters.

For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide .

Cookies -> (structure)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include cookies in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send cookies to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide .

Forward -> (string)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include cookies in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send cookies to the origin but not include them in the cache key, use origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.

Amazon S3 doesn’t process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.

WhitelistedNames -> (structure)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include cookies in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send cookies to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

Required if you specify whitelist for the value of Forward . A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.

If you specify all or none for the value of Forward , omit WhitelistedNames . If you change the value of Forward from whitelist to all or none and you don’t delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.

The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide .

You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers , if you specify 1 for Quantity and * for Name ).

DefaultTTL -> (long)

This field is deprecated. We recommend that you use the DefaultTTL field in a cache policy instead of this field. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide .

The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age , Cache-Control s-maxage , and Expires to objects.

Items -> (list)

Optional: A complex type that contains cache behaviors for this distribution. If Quantity is 0 , you can omit Items .

(structure)

A complex type that describes how CloudFront processes requests.

You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.

For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide .

If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.

To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.

To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.

For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide .

PathPattern -> (string)

The pattern (for example, images/*.jpg ) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.

Note

You can optionally include a slash (/ ) at the beginning of the path pattern. For example, /images/*.jpg . CloudFront behavior is the same with or without the leading / .

The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.

For more information, see Path Pattern in the Amazon CloudFront Developer Guide .

TargetOriginId -> (string)

The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.

TrustedSigners -> (structure)

Warning

We recommend using TrustedKeyGroups instead of TrustedSigners .

A list of Amazon Web Services account IDs whose public keys CloudFront can use to validate signed URLs or signed cookies.

When a cache behavior contains trusted signers, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with the private key of a CloudFront key pair in the trusted signer’s Amazon Web Services account. 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 .

Enabled -> (boolean)

This field is true if any of the Amazon Web Services accounts have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field is false .

Quantity -> (integer)

The number of Amazon Web Services accounts in the list.

Items -> (list)

A list of Amazon Web Services account identifiers.

(string)

TrustedKeyGroups -> (structure)

A list of key groups that CloudFront can use to validate signed URLs or signed cookies.

When a cache behavior contains trusted key groups, 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 .

Enabled -> (boolean)

This field is true if any of the key groups in the list have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field is false .

Quantity -> (integer)

The number of key groups in the list.

Items -> (list)

A list of key groups identifiers.

(string)

ViewerProtocolPolicy -> (string)

The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern . You can specify the following options:

  • allow-all : Viewers can use HTTP or HTTPS.

  • redirect-to-https : If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.

  • https-only : If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).

For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide .

Note

The only way to guarantee that viewers retrieve an object that was fetched from the origin using HTTPS is never to use any other protocol to fetch the object. If you have recently changed from HTTP to HTTPS, we recommend that you clear your objects’ cache because cached objects are protocol agnostic. That means that an edge location will return an object from the cache regardless of whether the current request protocol matches the protocol used previously. For more information, see Managing Cache Expiration in the Amazon CloudFront Developer Guide .

AllowedMethods -> (structure)

A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:

  • CloudFront forwards only GET and HEAD requests.

  • CloudFront forwards only GET , HEAD , and OPTIONS requests.

  • CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST , and DELETE requests.

If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can’t perform operations that you don’t want them to. For example, you might not want users to have permissions to delete objects from your origin.

Quantity -> (integer)

The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET , HEAD , and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST , and DELETE requests).

Items -> (list)

A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.

(string)

CachedMethods -> (structure)

A complex type that controls whether CloudFront caches the response to requests using the specified HTTP methods. There are two choices:

  • CloudFront caches responses to GET and HEAD requests.

  • CloudFront caches responses to GET , HEAD , and OPTIONS requests.

If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.

Quantity -> (integer)

The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET , HEAD , and OPTIONS requests).

The ARN of the Lambda@Edge function. You must specify the ARN of a function version; you can’t specify an alias or $LATEST.

EventType -> (string)

Specifies the event type that triggers a Lambda@Edge function invocation. You can specify the following values:

  • viewer-request : The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.

  • origin-request : The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn’t execute.

  • origin-response : The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn’t execute.

  • viewer-response : The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn’t execute.

IncludeBody -> (boolean)

A flag that allows a Lambda@Edge function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.

FunctionAssociations -> (structure)

If you want to include query strings in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send query strings to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys , if any:

If you specify true for QueryString and you don’t specify any values for QueryStringCacheKeys , CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.

If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys , CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.

If you specify false for QueryString , CloudFront doesn’t forward any query string parameters to the origin, and doesn’t cache based on query string parameters.

For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide .

Cookies -> (structure)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include cookies in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

If you want to send cookies to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide .

A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide .

Forward -> (string)

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.

If you want to include cookies in the cache key, use a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide .

The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide .

You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers , if you specify 1 for Quantity and * for Name ).

DefaultTTL -> (long)

This field is deprecated. We recommend that you use the DefaultTTL field in a cache policy instead of this field. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide .

The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age , Cache-Control s-maxage , and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide .

(structure)

A complex type that controls:

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

  • How long CloudFront caches HTTP status codes in the 4xx and 5xx range.

For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide .

ErrorCode -> (integer)

The HTTP status code for which you want to specify a custom error page and/or a caching duration.

ResponsePagePath -> (string)

The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode , for example, /4xx-errors/403-forbidden.html . If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:

  • The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors . Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/* .

  • The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.

If you specify a value for ResponsePagePath , you must also specify a value for ResponseCode .

We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can’t get the files that you want to return to viewers because the origin server is unavailable.

ResponseCode -> (string)

The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:

  • Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200 , the response typically won’t be intercepted.

  • If you don’t care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.

  • You might want to return a 200 status code (OK) and static website so your customers don’t know that your website is down.

If you specify a value for ResponseCode , you must also specify a value for ResponsePagePath .

ErrorCachingMinTTL -> (long)

The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode . When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.

For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide .

Comment -> (string)

  • ACMCertificateArn or IAMCertificateId (specify a value for one, not both)

  • MinimumProtocolVersion

  • SSLSupportMethod

IAMCertificateId -> (string)

If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in Identity and Access Management (IAM) , provide the ID of the IAM certificate.

If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVersion and SSLSupportMethod .

ACMCertificateArn -> (string)

If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in Certificate Manager (ACM) , provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region (us-east-1 ).

If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVersion and SSLSupportMethod .

SSLSupportMethod -> (string)

If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.

  • sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI) . This is recommended. Most browsers and clients support SNI.

  • vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.

  • static-ip - Do not specify this value unless your distribution has been enabled for this feature by the CloudFront team. If you have a use case that requires static IP addresses for a distribution, contact CloudFront through the Amazon Web Services Support Center .

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net , don’t set a value for this field.

MinimumProtocolVersion -> (string)

If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:

  • The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.

  • The ciphers that CloudFront can use to encrypt the content that it returns to viewers.

For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide .

Note

On the CloudFront console, this setting is called Security Policy .

When you’re using SNI only (you set SSLSupportMethod to sni-only ), you must specify TLSv1 or higher.

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true ), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.

Certificate -> (string)

This field is deprecated. Use one of the following fields instead:

  • ACMCertificateArn

  • IAMCertificateId

  • CloudFrontDefaultCertificate

CertificateSource -> (string)

This field is deprecated. Use one of the following fields instead:

  • ACMCertificateArn

  • IAMCertificateId

  • CloudFrontDefaultCertificate

Restrictions -> (structure)

GeoRestriction -> (structure)

A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.

RestrictionType -> (string)

The method that you want to use to restrict distribution of your content by country:

  • none : No geo restriction is enabled, meaning access to content is not restricted by client geo location.

  • blacklist : The Location elements specify the countries in which you don’t want CloudFront to distribute your content.

  • whitelist : The Location elements specify the countries in which you want CloudFront to distribute your content.

Quantity -> (integer)

When geo restriction is enabled , this is the number of countries in your whitelist or blacklist . Otherwise, when it is not enabled, Quantity is 0 , and you can omit Items .

Items -> (list)

A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content (whitelist ) or not distribute your content (blacklist ).

The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist . Include one Location element for each country.

CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.

(string)

WebACLId -> (string)

The Web ACL Id (if any) associated with the distribution.

HttpVersion -> (string)

Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2 . Viewers that don’t support HTTP/2 will automatically use an earlier version.

IsIPV6Enabled -> (boolean)

Whether CloudFront responds to IPv6 DNS requests with an IPv6 address for your distribution.

AliasICPRecordals -> (list)

Amazon Web Services services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they’ve added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.

For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with Amazon Web Services services in China .

(structure)

Amazon Web Services services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they’ve added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can’t configure it yourself.

For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with Amazon Web Services services in China .

CNAME -> (string)

A domain name associated with a distribution.

ICPRecordalStatus -> (string)

The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.

The status values returned are the following:

  • APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.

  • SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.

  • PENDING indicates that CloudFront can’t determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
