I've never found a satisfactory way of referencing keys in duct config without making those keys full integrant keys. What I've ended up doing instead is putting what I want to reuse into a "snippet" edn file and then #duct/includeing it wherever I want to reuse it. That would probably be overkill for you though in your case - easier just to reference the env var in multiple places instead.

Would be interested to hear if other folks have found a cleaner way of doing it though.

Something like aero's #ref.

I found this: https://github.com/duct-framework/duct/issues/96 It looks like you could put {:foo.api/origin [:duct/const]} in your duct_hierarchy.edn to avoid writing an init-key method

@U1UEABW4W nice!

I’ll submit some kind of documentation PR for this in the near-future
