EDIT: The essence of this question is: Can juju and/or jitsu do service co-location instead of having to use one node per service unit?

Does jitsu have a way to specify more than one particular machine to deploy multiple service units? For instance, I have ceph-mon deployed on three machines, but I want to deploy ceph-osd on the same three machines. As far as I can see, with jitsu I can only specify ONE machine for a particular service.

So, after doing:

jitsu deploy-to 1 --config local.yaml local:ceph-osd

I end up with:

services:

  ceph:

    charm: local:precise/ceph-91

    relations:

      mon:

      - ceph

    units:

      ceph/0:

        agent-state: pending

        machine: 1

        public-address: null

      ceph/1:

        agent-state: pending

        machine: 2

        public-address: null

      ceph/2:

        agent-state: pending

        machine: 3

        public-address: null

  ceph-osd:

    charm: local:precise/ceph-osd-7

    relations: {}

    units:

      ceph-osd/3:

        agent-state: pending

        machine: 1

        public-address: null

Now it appears I have no way of adding ceph-osd service units to machines 2 and 3.

I would like to do something like add-unit and add in the other two machines.

p.s. Can't add it, but I suggest adding the tag "jitsu" to this board.
