Connecting External Invokers to OW Kubernetes

Can we theoretically connect an external invoker container (not part of the Kubernetes deployment) to an OW Kubernetes installation ?

I already see that we can toggle the DockerContainerFactory choice but how would the Docker run command look like?

https://hub.docker.com/r/openwhisk/invoker

Start by reviewing the DockerContainerFactory choice and the openwhisk/invoker image referenced in the issue. Determine whether connecting an external invoker is supported and what deployment configuration or Docker command would be required; done would be a documented, validated connection procedure or a clearly scoped implementation request.
