Rename Iris Instances in Docker (or distinguishing them easily in other ways)

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.

Does anyone know how to achieve this or do you have other means to distinguish between management-portals of different instances in an easy way? Different background colours would be nice ;-)

Thanks, Thomas
