Right -- it's also worth noting that I'm only talking about the App Catalog here, not about Murano. Zun might be a bit too young for us to place all our eggs in the same basket, and some others pointed to how Murano is still viable alternative package for things that are more complex than a set of containers. What I'm questioning at the moment is the continued existence of a marketplace that did not catch fire as much as we hoped -- an app marketplace with not enough apps just hurts more than it helps imho. In particular, I'm fine if (for example) the Docker-wrapper murano package ends up being shipped as a standard/example package /in/ Murano, and continues to exist there as a "reasonable alternative for easily deploying docker apps" :) -- Thierry Carrez (ttx) __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
