Hello. I am new with istio and envoy.
I am trying to make configuration which could answer with code 200 and static text Hello World without any additional backend
I saw familiar request Support for envoy's direct_response?
And as I understand this could be achieved with EnvoyFilter.RouteConfigurationMatch.RouteMatch.Action and DIRECT_RESPONSE
My problem is I can’t find any simple manifests examples with EnvoyFilter.RouteConfigurationMatch
So far I successfully configured Gateway and VirtualService (with additional backend)
How can I now match it with EnvoyFilter and DIRECT_RESPONSE? Any familiar example of using EnvoyFilter.RouteConfigurationMatch would be extremely useful.
Thanks in advance!
