Is it possible to specify variable for a module to use it in every call of that module?

E.g i have multiple calling to docker and docker\_image modules inside playbook, but since i have a mac with docker inside VM, i should pass docker\_url variable on EACH call of docker module.  
Is it possible to define variable that will be used by every module automatically or redefine defaults for module?
