CfnRoute

class aws_cdk.aws_refactorspaces.CfnRoute(scope, id, *, application_identifier, environment_identifier, route_type, service_identifier, default_route=None, tags=None, uri_path_route=None)

Bases: CfnResource

Creates an AWS 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. .. epigraph:

In the ``AWS::RefactorSpaces::Route`` resource, you can only update the ``ActivationState`` property, which resides under the ``UriPathRoute`` and ``DefaultRoute`` properties. All other properties associated with the ``AWS::RefactorSpaces::Route`` cannot be updated, even though the property description might indicate otherwise. Updating all other properties will result in the replacement of Route.

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

URL Endpoints

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 a service endpoint resolves to a public IP address, Refactor Spaces routes traffic over the public internet. 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.

Refactor Spaces automatically resolves the public Domain Name System (DNS) names that are set in CreateService: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.

One-time health check

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 private URLs, a target group is created on the Network Load Balancer and the load balancer target group runs default target health checks. By default, the health check is run against the service endpoint URL. Optionally, the health check can be performed against a different protocol, port, and/or path using the CreateService:UrlEndpoint parameter. All other health check settings for the load balancer use the default values described in the Health checks for your target groups in the Elastic Load Balancing guide . The health check is considered successful if at least one target within the target group transitions to a healthy state.

AWS Lambda function endpoints

If the service has an AWS Lambda function endpoint, then Refactor Spaces configures the Lambda function’s resource policy to allow the application’s API Gateway to invoke the function.

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 AWS Lambda Developer Guide .

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.

Environments without a network bridge

When you create environments without a network bridge ( CreateEnvironment:NetworkFabricType is NONE) and you use your own networking infrastructure, you need to configure VPC to VPC connectivity between your network and the application proxy VPC. Route creation from the application proxy to service endpoints will fail if your network is not configured to connect to the application proxy VPC. For more information, see Create a route in the Refactor Spaces User Guide .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_dependency(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:

attribute_name (str) – The name of the attribute.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

DefaultRouteInputProperty

class CfnRoute.DefaultRouteInputProperty(*, activation_state)

Parameters:

activation_state (str) – If set to ACTIVE , traffic is forwarded to this route’s service after the route is created.
append_source_path (Union[bool, IResolvable, None]) – If set to true , this option appends the source path to the service URL endpoint.
include_child_paths (Union[bool, IResolvable, None]) – 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 (Optional[Sequence[str]]) – 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.
source_path (Optional[str]) – This is the path that Refactor Spaces uses to match traffic. Paths must start with / and are relative to the base of the application.
