Configuring Consul with Envoy's JWTAuthentication

Consul
1

I am trying to configure an Envoy Filter using Consul but it doesn’t seem to apply the configuration correctly.

apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
spec:
  config:
    lua_filter:
      name: envoy.filters.http.lua
      typed_config:
        "@type": type.googleapis.com/envoy.extensions.filters.http.lua.v3.Lua
        inline_code: |
          -- Called on the response path.
          function envoy_on_response(response_handle)
            response_handle:headers():add("x-custom-header", "Lua_Envoy_Filter")
            responde_handle:logError("Logging Hello")
          end

I then do kubectl apply -f proxydefaults_lua.yaml and reploy the app. But when I make the request to the app endpoint I don’t see the log or the response header.

To note that the app still works (I don’t get any errors) but I am expecting the request to pass through the lua filter which doesn’t seem to be the case

Is anybody able to help with this?

Consul 1.16 now supports Lua scripts via the Lua Envoy extension.
