I’m open to allowing magnum to pass a blob of data (such as a lump of JSON or YAML) to the Bay's native API. That approach strikes a balance that’s appropriate.

Hi,
<div class=""><br class="">
</div>
<div class="">At the present scenario, we can have mesos conductor with existing attributes[1]. Or we can add extra options like 'portMappings', 'instances', 'uris'[2]. And the other options is to take json file as input to 'magnum container-create' and dispatch
it to corresponding conductor. And the conductor will handle the json input. Let me know your opinions.</div>

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)<br class="">
<br class="">
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.<span class="Apple-converted-space"> </span><br class="">

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.<br class="">
<br class="">
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.<br class="">

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.<br class="">

><br class="">
> 1)Apps: combination of instances/containers running on multiple hosts representing a service.[2]<br class="">
> 2)Application Groups: Group of apps, for example we can have database application group which consists mongoDB app and MySQL App.[3]<br class="">
><br class="">
> So I think we need to have two resources 'apps' and 'appgroups' in 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.<br class="">
