Watch as OpenWhisk Triggers and Rules create Knative Eventing Channels and Subscriptions, respectively. And when a trigger fires see Knative Serving scale up the pods corresponding to the associated Action.

And, as a special bonus, watch the Knative helloworld-go sample service deployed via kubectl show up as an OpenWhisk Action and get called by firing an OpenWhisk Trigger.
