CfnVirtualNode L1 construct
Creates a virtual node within a service mesh.
A virtual node acts as a logical pointer to a particular task group, such as an Amazon ECS service or a Kubernetes deployment. When you create a virtual node, you can specify the service discovery information for your task group, and whether the proxy running in a task group will communicate with other proxies using Transport Layer Security (TLS).
You define a listener for any inbound traffic that your virtual node expects. Any virtual service that your virtual node expects to communicate to is specified as a backend .
The response metadata for your new virtual node contains the arn that is associated with the virtual node. Set this value to the full ARN; for example, arn:aws:appmesh:us-west-2:123456789012:myMesh/default/virtualNode/myApp ) as the APPMESH_RESOURCE_ARN environment variable for your task group's Envoy proxy container in your task definition or pod spec. This is then mapped to the node.id and node.cluster Envoy parameters.
By default, App Mesh uses the name of the resource you specified in
APPMESH_RESOURCE_ARNwhen Envoy is referring to itself in metrics and traces. You can override this behavior by setting theAPPMESH_RESOURCE_CLUSTERenvironment variable with your own name.
For more information about virtual nodes, see Virtual nodes . You must be using 1.15.0 or later of the Envoy image when setting these variables. For more information aboutApp Mesh Envoy variables, see Envoy image in the AWS App Mesh User Guide.

Parameters

This method has been renamed to addResourceDependency to more clearly set it apart from construct.node.addDependency. See the documentation of that function for more details.

notes
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
This method has been renamed to addResourceDependency, which makes it more clear that this method operates at a different level from the construct-level construct.node.addDependency() mechanism.
addMetadata(key: string, value: any): voiddef add_metadata(self, key: str, value: Any) -> Nonepublic void addMetadata(String key, Object value)public void AddMetadata(string key, object value)func AddMetadata(Key *string, Value interface{})#Add a value to the CloudFormation Resource Metadata.
addOverride(path: string, value: any): voiddef add_override(self, path: str, value: Any) -> Nonepublic void addOverride(String path, Object value)public void AddOverride(string path, object value)func AddOverride(Path *string, Value interface{})#Adds an override to the synthesized CloudFormation resource.
notes · 2 parameters
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,
typescript
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
would add the overrides
json
"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

addResourceDependency(target: CfnResource, reason?: string): voiddef add_resource_dependency(self, target: CfnResource, reason: typing.Optional[str] = None) -> Nonepublic void addResourceDependency(CfnResource target, String reason)public void AddResourceDependency(CfnResource target, string? reason = null)func AddResourceDependency(Target CfnResource, Reason *string)#Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
notes
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
This method only adds dependencies between L1 resources. If you are looking for a generic construct-to-construct dependency mechanism that works for all constructs including L2s, use construct.node.addDependency instead.

1 parameter
Parameters
strengthstrengthstrengthstrengthStrength— - The reference strength to use for this resource.
applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): voiddef apply_removal_policy(self, policy: typing.Optional[RemovalPolicy] = None, options: typing.Optional[RemovalPolicyOptions] = None) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)public void ApplyRemovalPolicy(RemovalPolicy? policy = null, RemovalPolicyOptions? options = null)func ApplyRemovalPolicy(Policy RemovalPolicy, Options RemovalPolicyOptions)#Sets the deletion policy of the resource based on the removal policy specified.
notes
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:

notes · 1 parameter · returns
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
xxxxX— Any object.
Returns: true if x is an object created from a class which extends Construct.
