VirtualService

class aws_cdk.aws_appmesh.VirtualService(scope, id, *, virtual_service_provider, virtual_service_name=None)

Bases: Resource

VirtualService represents a service inside an AppMesh.

It routes traffic either to a Virtual Node or to a Virtual Router.

See:

https://docs.aws.amazon.com/app-mesh/latest/userguide/virtual_services.html

ExampleMetadata:

infused

Example:

# mesh: appmesh.Mesh


node = appmesh.VirtualNode(self, "node",
    mesh=mesh,
    service_discovery=appmesh.ServiceDiscovery.dns("node")
)

virtual_service = appmesh.VirtualService(self, "service-1",
    virtual_service_provider=appmesh.VirtualServiceProvider.virtual_node(node),
    virtual_service_name="service1.domain.local"
)

node.add_backend(appmesh.Backend.virtual_service(virtual_service))
Parameters:
  • scope (Construct) –

  • id (str) –

  • virtual_service_provider (VirtualServiceProvider) – The VirtualNode or VirtualRouter which the VirtualService uses as its provider.

  • virtual_service_name (Optional[str]) – The name of the VirtualService. It is recommended this follows the fully-qualified domain name format, such as “my-service.default.svc.cluster.local”. Example value: service.domain.local Default: - A name is automatically generated

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

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).

Parameters:

policy (RemovalPolicy) –

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

mesh

The Mesh which the VirtualService belongs to.

node

The tree node.

stack

The stack in which this resource is defined.

virtual_service_arn

The Amazon Resource Name (ARN) for the virtual service.

virtual_service_name

The name of the VirtualService, it is recommended this follows the fully-qualified domain name format.

Static Methods

classmethod from_virtual_service_arn(scope, id, virtual_service_arn)

Import an existing VirtualService given an ARN.

Parameters:
  • scope (Construct) –

  • id (str) –

  • virtual_service_arn (str) –

Return type:

IVirtualService

classmethod from_virtual_service_attributes(scope, id, *, mesh, virtual_service_name)

Import an existing VirtualService given its attributes.

Parameters:
  • scope (Construct) –

  • id (str) –

  • mesh (IMesh) – The Mesh which the VirtualService belongs to.

  • virtual_service_name (str) – The name of the VirtualService, it is recommended this follows the fully-qualified domain name format.

Return type:

IVirtualService

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.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
