API Reference (API Version 2019-01-25)

CreateVirtualService

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.

Example

In the following example or examples, the Authorization header contents ( AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You need to learn how to sign HTTP requests only if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

Example

This example creates a virtual service named colorgateway.default.svc.cluster.local in the ecs-mesh service mesh.
