Add placement policies support
- This patch aims to add support for following placement policies in
addition to the default 'affinity' policy:
anti-affinity
soft-affinity
soft-anti-affinity
- This patch adds respective functional/unit test cases. To test
"anti-affinity" policy on the gate, changed the devstack functional
jobs `nodeset` from the default single node to "openstack-two-node".
- This patch also adds respective documentation and usage guide for
the above added policies.

VDU Placement policy
|
||||
====================
|
||||
|
||||
Openstack nova server groups can be used to control the affinity and
|
||||
anti-affinity scheduling policy for a group of VDU's. Below placement
|
||||
policies are supported::
|
||||
|
||||
Affinity:
|
||||
The policy that forces Nova to hosts the concerned VDUs in a same
|
||||
hypervisor.
|
||||
|
||||
Anti-Affinity:
|
||||
The policy that forces Nova to hosts the concerned VDUs each
|
||||
in a different hypervisor.
|
||||
|
||||
Soft-Affinity:
|
||||
The policy that forces nova about if it is not possible to
|
||||
schedule some VDUs to the same host then the subsequent VDUs will be
|
||||
scheduled together on another host. In this way operator can express a
|
||||
good-to-have relationship between a group of VDUs.
|
||||
|
||||
Soft-Anti-Affinity:
|
||||
The policy that forces nova about if it is not
|
||||
possible to schedule VDUs on different hosts then VDUs might get
|
||||
scheduled on a same host where another VDUs are running from the same
|
||||
group.

TOSCA schema for placement policy
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|

Tacker defines TOSCA schema for the placement policy as given below:

Sample TOSCA with placement policy
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Following TOSCA snippet shows the placement policy used in VNFD, in which vdu1
|
||||
and vdu2 are already defined VDUs.

The ``soft`` flag defines the softness of the placement policy.

Deploying placement TOSCA template using Tacker
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Once OpenStack/Devstack along with Tacker has been successfully installed,
|
||||
deploy a sample placement policy template from location given below:
|
||||
https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-placement-policy-anti-affinity.yaml
|
||||
|
||||

|
||||
VNF:

Added placement policy support. Operator can specify below placement
|
||||
policies in addition to `affinity` to VDU's:
|
||||
|
||||
* ``anti-affinity``
|
||||
* ``soft-affinity``
|
||||
* ``soft-anti-affinity``
|
||||
|
||||
Note: There is a known issue in nova that `late anti-affinity check`_ doesn't work
|
||||
in multi-cells environment. So it is highly recommended to deploy nova in single cell
|
||||
environment until this issue is resolved in multi-cells environment.
