S3Origin

class aws_cdk.aws_cloudfront_origins.S3Origin(bucket, *, origin_access_identity=None, origin_path=None, connection_attempts=None, connection_timeout=None, custom_headers=None, origin_id=None, origin_shield_enabled=None, origin_shield_region=None)

Bases: object

An Origin that is backed by an S3 bucket.

If the bucket is configured for website hosting, this origin will be configured to use the bucket as an HTTP server origin and will use the bucket’s configured website redirects and error handling. Otherwise, the origin is created as a bucket origin and will use CloudFront’s redirect and error handling.

Example:

# Adding an existing Lambda@Edge function created in a different stack
# to a CloudFront distribution.
# s3_bucket: s3.Bucket

function_version = lambda_.Version.from_version_arn(self, "Version", "arn:aws:lambda:us-east-1:123456789012:function:functionName:1")

cloudfront.Distribution(self, "distro",
    default_behavior=cloudfront.BehaviorOptions(
        origin=origins.S3Origin(s3_bucket),
        edge_lambdas=[cloudfront.EdgeLambda(
            function_version=function_version,
            event_type=cloudfront.LambdaEdgeEventType.VIEWER_REQUEST
        )
        ]
    )
)
Parameters:

  • bucket (IBucket) –

  • origin_access_identity (Optional[IOriginAccessIdentity]) – An optional Origin Access Identity of the origin identity cloudfront will use when calling your s3 bucket. Default: - An Origin Access Identity will be created.

  • origin_path (Optional[str]) – An optional path that CloudFront appends to the origin domain name when CloudFront requests content from the origin. Must begin, but not end, with ‘/’ (e.g., ‘/production/images’). Default: ‘/’

  • connection_attempts (Union[int, float, None]) – The number of times that CloudFront attempts to connect to the origin; valid values are 1, 2, or 3 attempts. Default: 3

  • connection_timeout (Optional[Duration]) – The number of seconds that CloudFront waits when trying to establish a connection to the origin. Valid values are 1-10 seconds, inclusive. Default: Duration.seconds(10)

  • custom_headers (Optional[Mapping[str, str]]) – A list of HTTP header names and values that CloudFront adds to requests it sends to the origin. Default: {}

  • origin_id (Optional[str]) – A unique identifier for the origin. This value must be unique within the distribution. Default: - an originid will be generated for you

  • origin_shield_enabled (Optional[bool]) – Origin Shield is enabled by setting originShieldRegion to a valid region, after this to disable Origin Shield again you must set this flag to false. Default: - true

  • origin_shield_region (Optional[str]) – When you enable Origin Shield in the AWS Region that has the lowest latency to your origin, you can get better network performance. Default: - origin shield not enabled
