[openstack-dev] [magnum]swarm + compose = k8s?

definitely ;), but the are some thoughts to Tom’s email.

I agree that we shouldn't reinvent apis, but I don’t think Magnum should only focus at deployment (I feel we will become another Puppet/Chef/Ansible module if we do it ):)
I belive our goal should be seamlessly integrate Kub/Mesos/Swarm to OpenStack ecosystem (Neutron/Cinder/Barbican/etc) even if we need to step in to Kub/Mesos/Swarm communities for that.

This is definitely a topic we should cover in Tokyo.

This has been my thinking in the last couple of months to completely deprecate the COE specific APIs such as pod/service/rc and container.

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.

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?
Even if we want to orchestrate these in a Heat template, the corresponding heat resources can just interface with k8s instead of Magnum.
Ton Ngo,

Also I belive docker compose is just command line tool which doesn’t have any api or scheduling features.
But during last Docker Conf hackathon PayPal folks implemented docker compose executor for Mesos (https://github.com/mohitsoni/compose-executor)
which can give you pod like experience.

Wanghua,

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.

Thanks,

Adrian

Hi folks,

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.

Wanghua
