class aws_cdk.aws_cloudfront_origins.LoadBalancerV2OriginProps(*, connection_attempts=None, connection_timeout=None, custom_headers=None, origin_access_control_id=None, origin_id=None, origin_shield_enabled=None, origin_shield_region=None, origin_path=None, http_port=None, https_port=None, keepalive_timeout=None, origin_ssl_protocols=None, protocol_policy=None, read_timeout=None)

Bases: HttpOriginProps

Properties for an Origin backed by a v2 load balancer.

Parameters:

  • 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_access_control_id (Optional[str]) – The unique identifier of an origin access control for this origin. Default: - no origin access control

  • 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

  • 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: ‘/’

  • http_port (Union[int, float, None]) – The HTTP port that CloudFront uses to connect to the origin. Default: 80

  • https_port (Union[int, float, None]) – The HTTPS port that CloudFront uses to connect to the origin. Default: 443

  • keepalive_timeout (Optional[Duration]) – Specifies how long, in seconds, CloudFront persists its connection to the origin. The valid range is from 1 to 180 seconds, inclusive. Note that values over 60 seconds are possible only after a limit increase request for the origin response timeout quota has been approved in the target account; otherwise, values over 60 seconds will produce an error at deploy time. Default: Duration.seconds(5)

  • origin_ssl_protocols (Optional[Sequence[OriginSslPolicy]]) – The SSL versions to use when interacting with the origin. Default: OriginSslPolicy.TLS_V1_2

  • protocol_policy (Optional[OriginProtocolPolicy]) – Specifies the protocol (HTTP or HTTPS) that CloudFront uses to connect to the origin. Default: OriginProtocolPolicy.HTTPS_ONLY

  • read_timeout (Optional[Duration]) – Specifies how long, in seconds, CloudFront waits for a response from the origin, also known as the origin response timeout. The valid range is from 1 to 180 seconds, inclusive. Note that values over 60 seconds are possible only after a limit increase request for the origin response timeout quota has been approved in the target account; otherwise, values over 60 seconds will produce an error at deploy time. Default: Duration.seconds(30)
