**Example 1: To create a new virtual node that uses DNS for discovery** The following ``create-virtual-node`` example uses a JSON input file to create a virtual node that uses DNS for service discovery. :: aws appmesh create-virtual-node \ --cli-input-json file://create-virtual-node-dns.json Contents of ``create-virtual-node-dns.json``:: { "meshName": "app1", "spec": { "listeners": [ { "portMapping": { "port": 80, "protocol": "http" } } ], "serviceDiscovery": { "dns": { "hostname": "serviceBv1.svc.cluster.local" } } }, "virtualNodeName": "vnServiceBv1" } Output:: { "virtualNode": { "meshName": "app1", "metadata": { "arn": "arn:aws:appmesh:us-east-1:123456789012:mesh/app1/virtualNode/vnServiceBv1", "createdAt": 1563810019.874, "lastUpdatedAt": 1563810019.874, "uid": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE", "version": 1 }, "spec": { "listeners": [ { "portMapping": { "port": 80, "protocol": "http" } } ], "serviceDiscovery": { "dns": { "hostname": "serviceBv1.svc.cluster.local" } } }, "status": { "status": "ACTIVE" }, "virtualNodeName": "vnServiceBv1" } } **Example 2: To create a new virtual node that uses AWS Cloud Map for discovery** The following ``create-virtual-node`` example uses a JSON input file to create a virtual node that uses AWS Cloud Map for service discovery. :: aws appmesh create-virtual-node \ --cli-input-json file://create-virtual-node-cloud-map.json Contents of ``create-virtual-node-cloud-map.json``:: { "meshName": "app1", "spec": { "backends": [ { "virtualService": { "virtualServiceName": "serviceA.svc.cluster.local" } } ], "listeners": [ { "portMapping": { "port": 80, "protocol": "http" } } ], "serviceDiscovery": { "awsCloudMap": { "attributes": [ { "key": "Environment", "value": "Testing" } ], "namespaceName": "namespace1", "serviceName": "serviceA" } } }, "virtualNodeName": "vnServiceA" } Output:: { "virtualNode": { "meshName": "app1", "metadata": { "arn": "arn:aws:appmesh:us-east-1:123456789012:mesh/app1/virtualNode/vnServiceA", "createdAt": 1563810859.465, "lastUpdatedAt": 1563810859.465, "uid": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE", "version": 1 }, "spec": { "backends": [ { "virtualService": { "virtualServiceName": "serviceA.svc.cluster.local" } } ], "listeners": [ { "portMapping": { "port": 80, "protocol": "http" } } ], "serviceDiscovery": { "awsCloudMap": { "attributes": [ { "key": "Environment", "value": "Testing" } ], "namespaceName": "namespace1", "serviceName": "serviceA" } } }, "status": { "status": "ACTIVE" }, "virtualNodeName": "vnServiceA" } } For more information, see `Virtual Nodes <https://docs.aws.amazon.com/app-mesh/latest/userguide/virtual_nodes.html>`__ in the *AWS App Mesh User Guide*.
