create-virtual-service¶

Description¶

Creates a virtual service within a service mesh.

A virtual service is an abstraction of a real service that is provided by a virtual node directly or indirectly by means of a virtual router. Dependent services call your virtual service by its virtualServiceName , and those requests are routed to the virtual node or virtual router that is specified as the provider for the virtual service.

For more information about virtual services, see Virtual services .

Synopsis¶

  create-virtual-service
[--client-token <value>]
--mesh-name <value>
[--mesh-owner <value>]
--spec <value>
[--tags <value>]
--virtual-service-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--client-token (string)

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Up to 36 letters, numbers, hyphens, and underscores are allowed.

--mesh-name (string)

The name of the service mesh to create the virtual service in.

--mesh-owner (string)

The Amazon Web Services IAM account ID of the service mesh owner. If the account ID is not your own, then the account that you specify must share the mesh with your account before you can create the resource in the service mesh. For more information about mesh sharing, see Working with shared meshes .

--spec (structure)

The virtual service specification to apply.

provider -> (structure)

The App Mesh object that is acting as the provider for a virtual service. You can specify a single virtual node or virtual router.

virtualNode -> (structure)

The virtual node associated with a virtual service.

virtualNodeName -> (string)

The name of the virtual node that is acting as a service provider.

virtualRouter -> (structure)

The virtual router associated with a virtual service.

virtualRouterName -> (string)

The name of the virtual router that is acting as a service provider.

Shorthand Syntax:

provider={virtualNode={virtualNodeName=string},virtualRouter={virtualRouterName=string}}

JSON Syntax:

{
  "provider": {
    "virtualNode": {
      "virtualNodeName": "string"
    },
    "virtualRouter": {
      "virtualRouterName": "string"
    }
  }
}

--tags (list)

Optional metadata that you can apply to the virtual service to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters.

(structure)

Optional metadata that you apply to a resource to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

Shorthand Syntax:

key=string,value=string ...

JSON Syntax:

[
  {
    "key": "string",
    "value": "string"
  }
  ...
]

--virtual-service-name (string)

The name to use for the virtual service.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To create a new virtual service with a virtual node provider

The following create-virtual-service example uses a JSON input file to create a virtual service with a virtual node provider.

aws appmesh create-virtual-service \
    --cli-input-json file://create-virtual-service-virtual-node.json

Contents of create-virtual-service-virtual-node.json:

{
    "meshName": "app1",
    "spec": {
        "provider": {
            "virtualNode": {
                "virtualNodeName": "vnServiceA"
            }
        }
    },
    "virtualServiceName": "serviceA.svc.cluster.local"
}

Output:

{
    "virtualService": {
        "meshName": "app1",
        "metadata": {
            "arn": "arn:aws:appmesh:us-east-1:123456789012:mesh/app1/virtualService/serviceA.svc.cluster.local",
            "createdAt": 1563810859.474,

            "version": 2
        },
        "spec": {
            "provider": {
                "virtualNode": {
                    "virtualNodeName": "vnServiceA"
                }
            }
        },
        "status": {
            "status": "ACTIVE"
        },

Example 2: To create a new virtual service with a virtual router provider

The following create-virtual-service example uses a JSON input file to create a virtual service with a virtual router provider.

aws appmesh create-virtual-service \
    --cli-input-json file://create-virtual-service-virtual-router.json
