Destination Selection

In the Hello World example, we saw how Gloo Edge uses a Virtual Service Custom Resource (CR) to allow users to specify routes to a particular destination, or Upstream. Each route on a Virtual Service includes a matcher, specifying the rules to determine if a request should be passed along the route. In the basic example, we used an exact match for a particular path. We’ll now look at how to configure a route on a Virtual Service with different kinds of matching logic and matchers.

The following are the different aspects of the request that you can match against a route rule. Each aspect is combined with the others in a logical AND, i.e. all aspects must test true for the route to match and the specified route action to be taken.

We recommend starting with Path Matching first and then reviewing the other matching types in turn.
