Is it possible to set arbitrary labels on containers, and access them in the haproxy config template?

Maybe this is possible already, or maybe this is a feature request. I'd like to be able to add arbitrary key/values on my containers, and then access them in the template that generates the HAProxy configuration.

If this is already possible, can you give me some pointers as to how I can do this?

No this is not implemented today. What are you trying to do?

I need to set a header for requests that are going to one of my containers. One idea was to just compare $host.ContextRoot.Name, but it would be more flexible if I could add a label indicating the header value.
