OK thank you for making it clearer, now I understand where you're
coming from. I do agree with this sentiment. I don't have any
experience with zun but it sounds like it's the least-cost way to
deploy a docker at for the environments where it's installed.
I think overall the app catalog was an interesting experiment, but I
don't think it makes sense to continue as-is. Unless someone comes up
with a compelling new direction, I don't see much point in keeping it
running. Especially since it sounds like Mirantis is on board (and
the connection to a murano ecosystem was the only thing I saw that
might be interesting).
