As we now support Mesos, Kubernetes and Docker Swarm its going to be very difficult and probably a wasted effort trying to consolidate their separate APIs under a single Magnum API.

I'm starting to see Magnum as COEDaaS - Container Orchestration Engine Deployment as a Service.<br>

<p>Would it make sense to ask the opposite of Wanghua's question: should pod/service/rc be deprecated if the user can easily get to the k8s api?
<br>
Even if we want to orchestrate these in a Heat template, the corresponding heat resources can just interface with k8s instead of Magnum.<br>

Wanghua,<br>
<br>
I do follow your logic, but docker-compose only needs the docker API to operate. We are intentionally avoiding re-inventing the wheel. Our goal is not to replace docker swarm (or other existing systems), but to compliment it/them. We want to offer users of
Docker the richness of native APIs and supporting tools. This way they will not need to compromise features or wait longer for us to implement each new feature as it is added. Keep in mind that our pod, service, and replication controller resources pre-date
this philosophy. If we started out with the current approach, those would not exist in Magnum.<br>
<br>
Thanks,<br>

Hi folks,<br>
<br>
Magnum now exposes service, pod, etc to users in kubernetes coe, but exposes container in swarm coe. As I know, swarm is only a scheduler of container, which is like nova in openstack. Docker compose is a orchestration program which is like heat in openstack.
k8s is the combination of scheduler and orchestration. So I think it is better to expose the apis in compose to users which are at the same level as k8s.<br>
<br>
<br>
Regards<br>
Wanghua<br>
