AWS::AppMesh::VirtualNode VirtualNodeSpec
An object that represents the specification of a virtual node.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
JSON
{ "BackendDefaults" :BackendDefaults, "Backends" :[ Backend, ... ], "Listeners" :[ Listener, ... ], "Logging" :Logging, "ServiceDiscovery" :ServiceDiscovery}
YAML
BackendDefaults:BackendDefaultsBackends:- BackendListeners:- ListenerLogging:LoggingServiceDiscovery:ServiceDiscovery
Properties
BackendDefaults-
A reference to an object that represents the defaults for backends.
Required: No
Type: BackendDefaults

Backends-
The backends that the virtual node is expected to send outbound traffic to.
Important
App Mesh doesn't validate the existence of those virtual services specified in backends. This is to prevent a cyclic dependency between virtual nodes and virtual services creation. Make sure the virtual service name is correct. The virtual service can be created afterwards if it doesn't already exist.
