Comment 3 for bug 1524284

ISO version: http://paste.openstack.org/show/483967/

Steps:

  1. Create config file controller.yaml: http://paste.openstack.org/show/483968/ and mongo.yaml: http://paste.openstack.org/show/483966/

  2. Upload config for controller and mongo roles:

    fuel openstack-config --role controller --env 1 --upload --file controller.yaml
    fuel openstack-config --role mongo --env 1 --upload --file mongo.yaml

  3. List configs:

    [root@nailgun ~]# fuel openstack-config --list --env 1
    id | is_active | config_type | cluster_id | node_id | node_role
    ---|-----------|-------------|------------|---------|-----------
    4 | True | role | 1 | None | mongo
    5 | True | role | 1 | None | controller

3. Execute config on node with this 2 roles:

    [root@nailgun ~]# date
    Fri Jan 15 07:40:19 UTC 2016
    [root@nailgun ~]# fuel openstack-config --execute --env 1 --node 1

4. Wait when deployemnt task will be finished and check hiere on that node:

root@node-1:~# cat /etc/hiera/override/configuration/role.yaml
configuration:
  nova_config:
    DEFAULT/debug: {value: true}
root@node-1:~#

Here we can see that only second config was applied. In Nova.conf only first parameter was changed
