Choosing a Scheduler

The :ref:`scheduler` creates, starts, stops, and destroys each :ref:`container`

    ##start k8sapps
    {{range $kapp := lsdir "/registry/services/specs/default"}}
    upstream {{base $kapp}} {
        {{$appdir := printf "/registry/services/specs/default/%s" $kapp}}{{range gets $appdir}}
        server {{$data := json .Value}}{{$data.spec.portalIP}}:80;

Once we start core-os machine with flannel. which gives a containers a feel of overlay network. Every container will have a unique IP.

1. Container port shouldn't be bind mounted.
2. Publisher should be able to publish container IP and Port as each APP container is unique.
3. Only Jobstate.Up, Destroyed, Crashed, Error.
4. Moving scale logic from models.py to schedulers accordingly.
5. Allow custom interfaces and IPs while creating user-data.
6. Make Registry URL based or run registry in every host.
7. Create services for each App
