Direct Response Action
Gloo Edge allows you to specify a direct response instead of routing to a destination.
Setup
This guide assumes that you have deployed Gloo to the gloo-system
namespace and that the glooctl
command line utility
is installed on your machine. glooctl
provides several convenient functions to view, manipulate, and debug Gloo resources;
in particular, it is worth mentioning the following command, which we will use each time we need to retrieve the URL of
the Gloo Gateway that is running inside your cluster:
glooctl proxy url
Creating a direct response virtual service
Let’s create a virtual service with a direct response action instead of a route action, returning a 200 “Hello, World!” response:
Now if we curl the route, we should get the 200 response and see the message:
curl -H "Host: foo" $(glooctl proxy url)
This will return the following message:
Hello, world!
Summary
A virtual service route can be configured with a direct response instead of a routing action.
Let’s clean up the virtual service we created:
