AWS::S3::Bucket RoutingRuleCondition - AWS CloudFormation
SyntaxPropertiesExamples

AWS::S3::Bucket RoutingRuleCondition

A container for describing a condition that must be met for the specified redirect to apply. For example, 1. If request is for pages in the /docs folder, redirect to the /documents folder. 2. If request results in HTTP error 4xx, redirect request to another host where you might process the error.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "HttpErrorCodeReturnedEquals" : String,
  "KeyPrefixEquals" : String
}

Properties

HttpErrorCodeReturnedEquals

The HTTP error code when the redirect is applied. In the event of an error, if the error code equals this value, then the specified redirect is applied.

Required when parent element Condition is specified and sibling KeyPrefixEquals is not specified. If both are specified, then both must be true for the redirect to be applied.

Required: Conditional

Type: String

Update requires: No interruption

KeyPrefixEquals

The object key name prefix when the redirect is applied. For example, to redirect requests for ExamplePage.html, the key prefix will be ExamplePage.html. To redirect request for all pages with the prefix docs/, the key prefix will be /docs, which identifies all objects in the docs/ folder.

Required when the parent element Condition is specified and sibling HttpErrorCodeReturnedEquals is not specified. If both conditions are specified, both must be true for the redirect to be applied.

Required: Conditional

Type: String

Update requires: No interruption

Examples

Configure a static website with a routing rule

In this example, AWS::S3::Bucket's Fn::GetAtt values are used to provide outputs. If an HTTP 404 error occurs, the routing rule redirects requests to an EC2 instance and inserts the object key prefix report-404/ in the redirect. For example, if you request a page called ExamplePage.html and it results in an HTTP 404 error, the request is routed to a page called report-404/ExamplePage.html on the specified instance. For all other HTTP error codes, error.html is returned.

This example also specifies a metrics configuration called EntireBucket that enables CloudWatch request metrics at the bucket level.
