Is there not a way to pass arguments from command line to the Pod specification? There should be, because this is not the first time that a Docker argument is needed when calling a Pod instance, whether dynamic or staticly defined.
I could have Pod1.yaml, Pod2.yaml, and have an Ipaddress, and Port number for reach separate Pod that is defined.
