create_route

create_route(**kwargs)

Creates an Amazon Web Services Migration Hub Refactor Spaces route. The account owner of the service resource is always the environment owner, regardless of which account creates the route. Routes target a service in the application. If an application does not have any routes, then the first route must be created as a DEFAULT RouteType .

When created, the default route defaults to an active state so state is not a required input. However, like all other state values the state of the default route can be updated after creation, but only when all other routes are also inactive. Conversely, no route can be active without the default route also being active.

When you create a route, Refactor Spaces configures the Amazon API Gateway to send traffic to the target service as follows:

  • If the service has a URL endpoint, and the endpoint resolves to a private IP address, Refactor Spaces routes traffic using the API Gateway VPC link.
  • If the service has a URL endpoint, and the endpoint resolves to a public IP address, Refactor Spaces routes traffic over the public internet.
  • If the service has an Lambda function endpoint, then Refactor Spaces configures the Lambda function's resource policy to allow the application's API Gateway to invoke the function.

A one-time health check is performed on the service when either the route is updated from inactive to active, or when it is created with an active state. If the health check fails, the route transitions the route state to FAILED , an error code of SERVICE_ENDPOINT_HEALTH_CHECK_FAILURE is provided, and no traffic is sent to the service.

For Lambda functions, the Lambda function state is checked. If the function is not active, the function configuration is updated so that Lambda resources are provisioned. If the Lambda state is Failed , then the route creation fails. For more information, see the GetFunctionConfiguration's State response parameter in the Lambda Developer Guide .

For Lambda endpoints, a check is performed to determine that a Lambda function with the specified ARN exists. If it does not exist, the health check fails. For public URLs, a connection is opened to the public endpoint. If the URL is not reachable, the health check fails.

Refactor Spaces automatically resolves the public Domain Name System (DNS) names that are set in CreateServiceRequest$UrlEndpoint when you create a service. The DNS names resolve when the DNS time-to-live (TTL) expires, or every 60 seconds for TTLs less than 60 seconds. This periodic DNS resolution ensures that the route configuration remains up-to-date.

For private URLS, a target group is created on the Elastic Load Balancing and the target group health check is run. The HealthCheckProtocol , HealthCheckPort , and HealthCheckPath are the same protocol, port, and path specified in the URL or health URL, if used. All other settings use the default values, as described in Health checks for your target groups. The health check is considered successful if at least one target within the target group transitions to a healthy state.

Services can have HTTP or HTTPS URL endpoints. For HTTPS URLs, publicly-signed certificates are supported. Private Certificate Authorities (CAs) are permitted only if the CA's domain is also publicly resolvable.

    }
)
Parameters
  • ApplicationIdentifier (string) --

    [REQUIRED]

    The ID of the application within which the route is being created.

  • ClientToken (string) --

    A unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

    This field is autopopulated if not provided.

  • DefaultRoute (dict) --

    Configuration for the default route type.

    • ActivationState (string) --

      If set to ACTIVE , traffic is forwarded to this route’s service after the route is created.

  • EnvironmentIdentifier (string) --

    [REQUIRED]

    The ID of the environment in which the route is created.

  • RouteType (string) --

    [REQUIRED]

    The route type of the route. DEFAULT indicates that all traffic that does not match another route is forwarded to the default route. Applications must have a default route before any other routes can be created. URI_PATH indicates a route that is based on a URI path.

  • ServiceIdentifier (string) --

    [REQUIRED]

    The ID of the service in which the route is created. Traffic that matches this route is forwarded to this service.

  • Tags (dict) --

    The tags to assign to the route. A tag is a label that you assign to an Amazon Web Services resource. Each tag consists of a key-value pair..

    • (string) --
      • (string) --
  • UriPathRoute (dict) --

    The configuration for the URI path route type.

    • ActivationState (string) -- [REQUIRED]

      If set to ACTIVE , traffic is forwarded to this route’s service after the route is created.

    • IncludeChildPaths (boolean) --

      Indicates whether to match all subpaths of the given source path. If this value is false , requests must match the source path exactly before they are forwarded to this route's service.

    • Methods (list) --

      A list of HTTP methods to match. An empty list matches all values. If a method is present, only HTTP requests using that method are forwarded to this route’s service.

      • (string) --
    • SourcePath (string) -- [REQUIRED]

      The path to use to match traffic. Paths must start with / and are relative to the base of the application.
