@hongin, @adrian I agree with you. So can we go ahead with magnum container-create(delete) ... for mesos bay (which actually create mesos(marathon) app internally)? @jay, yes we multiple frameworks which are using mesos lib. But the mesos bay we are creating uses marathon. And we had discussion in irc on this topic, and I was asked to implement initial version for marathon. And agree with you to have unified client interface for creating pod,app. RegardsBharath T

One problem I want to mention is that for mesos integration, we cannot limited to Marathon + Mesos as there are many frameworks can run on top of Mesos, such as Chronos, Kubernetes etc, we may need to consider more for Mesos integration as there is a huge eco-system build on top of Mesos.

If there is a strong desire to add these things, we could allow it by having a plugin/extensions interface for the Magnum API to allow additional COE specific features. Honestly, it’s just going to be a nuisance to keep up with the various upstreams until they become completely stable from an API perspective, and no additional changes are likely. All of our COE’s still have plenty of maturation ahead of them, so this is the wrong time to wrap them. If someone really wants apps and appgroups, (s)he could add that to an experimental branch of the magnum client, and have it interact with the marathon API directly rather than trying to represent those resources in Magnum. If that tool became popular, then we could revisit this topic for further consideration.
