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_ARN
when Envoy is referring to itself in metrics and traces. You can override this behavior
by setting the APPMESH_RESOURCE_CLUSTER environment 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 App Mesh User Guide.
For .NET Core this operation is only available in asynchronous form. Please refer to CreateVirtualNodeAsync.
