CreateRoute
Creates a route that is associated with a virtual router.
You can use the
prefix parameter in your route specification for path-based
routing of requests. For example, if your virtual service name is
my-service.local and you want the route to match requests to
my-service.local/metrics, your prefix should be
/metrics.
If your route matches a request, you can distribute traffic to one or more target virtual nodes with relative weighting.

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
The following example creates a route named
colorgateway-route for
the
colorgateway-vr virtual router in the
ecs-mesh service
mesh. The route directs all traffic to the
colorgateway-vn virtual
node.
