How to send dashboard command with multiple replicas?

[Bart Koelman (bart-vmware)]

I'd like to add a command to the dashboard that sends an HTTP request to the replica it was selected for.

I've tried the following, but it always sends the command to the first replica:

var apiService = builder.AddProject...
    .WithReplicas(2)
    .WithHttpCommand("/demo", "Demo");

I can pass a CommandOptions and set a callback for PrepareRequest, but how do I find the dynamic port number that is assigned to the instance in the callback?

Replicas are not represented in the app model so there's really no way to identify a specific replica once we're back in the app model. We need to re-think about the implications of replicas when we do them over.
