===================================
VNF scaling with reserved resources
===================================
Tacker allows you to configure reserved compute resources in reservation
policy. The compute resources should be first reserved in the OpenStack
``Blazar`` service by creating leases which can then be configured in the
VNFD template.
TOSCA schema for reservation policy
-----------------------------------
Tacker defines TOSCA schema for the reservation policy as given below:
.. code-block:: yaml
tosca.policies.tacker.Reservation:
derived_from: tosca.policies.Reservation
reservation:
start_actions:
type: map
entry_schema:
type: string
required: true
before_end_actions:
type: map
entry_schema:
type: string
required: true
end_actions:
type: map
entry_schema:
type: string
required: true
properties:
lease_id:
type: string
required: true
Following TOSCA snippet shows VNFD template using reservation policy.
In this policy, you can see there are three different types of actions.
#. start_actions
#. before_end_actions
#. end_actions
In these actions, you can configure multiple actions but scaling policy is
mandatory in start_actions and one of before_end_actions or end_actions.
The scaling policy configured in the start_actions will be scaling-out policy
so configure max_instances as per the compute resources reserved in the Blazar
service and the scaling policy configured in either of before_end_actions or
end_actions will be scaling-in policy so configure min_instances to 0.
Also, `default_instances` should be set to 0 because we don't want VDUs until
tacker receives the lease start trigger from Blazar through Aodh service.
The parameter `increment` should also be set equal to `max_instances` as
tacker will receive lease start trigger only once during the lifecycle
of a lease.
.. code-block:: yaml
policies:
- RSV:
type: tosca.policies.tacker.Reservation
reservation:
start_actions: [SP_RSV, log]
before_end_actions: [SP_RSV]
end_actions: [noop]
properties:
lease_id: { get_input: lease_id }
- SP_RSV:
type: tosca.policies.tacker.Scaling
properties:
increment: 2
cooldown: 120
min_instances: 0
max_instances: 2
default_instances: 0
targets: [VDU1]
Installation and configurations
-------------------------------
1. You need Blazar, ceilometer and Aodh OpenStack services.
2. Modify the below configuration files:
/etc/blazar/blazar.conf:
.. code-block:: yaml
[oslo_messaging_notifications]
driver = messaging, log
/etc/ceilometer/event_pipeline.yaml:
.. code-block:: yaml
sinks:
- name: event_sink
transformers:
publishers:
- gnocchi://?archive_policy=low&filter_project=gnocchi_swift
- notifier://
- notifier://?topic=alarm.all
/etc/ceilometer/event_definitions.yaml:
.. code-block:: yaml
- event_type: lease.event.start_lease
traits: &lease_traits
lease_id:
fields: payload.lease_id
project_id:
fields: payload.project_id
user_id:
fields: payload.user_id
start_date:

end_date:
fields: payload.end_date
- event_type: lease.event.before_end_lease
traits: *lease_traits
- event_type: lease.event.end_lease

2. Replace the flavor, lease_id and server_group_id value in the parameter file
given for reservation with the lease response flavor, lease_id and
server_group_id value.
Ref:
``samples/tosca-templates/vnfd/tosca-vnfd-instance-reservation-param-values.yaml``
.. note::
The `server_group_id` parameter should be specified in VDU section only
when reservation resource type is `virtual:instance`. Operator shouldn't
configure both placement policy under policies and server_group_id in VDU
in VNFD template otherwise the server_group_id specified in VDU will be
superseded by the server group that will be created by heat for placement
policy.

``Scaling process``
After the lease lifecycle begins in the Blazar service, tacker will receive a
start_lease event at ``2019-04-24T20:00:00``. Tacker will start scaling-out
process and you should notice VDUs will be created as per the ``increment``
value.
Similarly, when before_end_lease event is triggered at ``2019-07-09T20:00``,
tacker will start scaling-in process in which VDUs will be deleted as per the
``increment`` value.
When reservation resource type is physical:host
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. Create a lease for compute host reservation:
.. sourcecode:: console
$ blazar lease-create --physical-reservation min=1,max=1,hypervisor_properties='[">=", "$vcpus", "2"]' --start-date
"2019-04-08 12:00" --end-date "2019-07-09 12:00" lease-1
