@bharath,
1) actually, if you mean use container-create(delete) to do on mesos bay
for apps. I am not sure how different the interface between docker
interface and mesos interface. One point that when you introduce that
feature, please not make docker container interface more complicated than
now. I worried that because it would confuse end-users a lot than the
unified benefits. (maybe as optional parameter to pass one json file to
create containers in mesos)
2) For the unified interface, I think it need more thoughts, we need not
bring more trouble to end-users to learn new concepts or interfaces, except
we could have more clear interface, but different COES vary a lot. It is
very challenge.
Thanks
Best Wishes,

@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.

+1.
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.

Bharath,
I agree with Hongbin on this. Let’s not expand magnum to deal with
apps or appgroups in the near term. 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.

Personally, I don’t like to introduce “apps” and “appgroups”
resources to Magnum, because they are already provided by native tool
[1]. I couldn’t see the benefits to implement a wrapper API to offer
what native tool already offers. However, if you can point out a
valid use case to wrap the API, I will give it more thoughts.

mesos conductor like we have pod and rc for k8s. And regarding
'magnum container' command, we can create, delete and retrieve
container details as part of mesos app itself(container = app with 1
instance). Though I think in mesos case 'magnum app-create ..." and
'magnum container-create ...' will use the same REST API for both
cases.
