--
-- 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
-- <https://docs.aws.amazon.com/app-mesh/latest/userguide/virtual_nodes.html 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
-- <https://docs.aws.amazon.com/app-mesh/latest/userguide/envoy.html Envoy image>
-- in the App Mesh User Guide.
