Usage
=====

Cinder provides an infrastructure for managing volumes in OpenStack.
Originally, this project was the Nova component called ``nova-volume``
and starting from the Folsom OpenStack release it has become an independent
project.

This file provides the sample configurations for different use cases:

* Pillar sample of a basic Cinder configuration:

  The pillar structure defines ``cinder-api`` and ``cinder-scheduler`` inside
  the ``controller`` role and ``cinder-volume`` inside the to ``volume``
  role.

* Auditing filter (CADF) enablement:

  .. code-block:: yaml

    cinder:
      controller:
        audit:
          enabled: true
      ....
          filter_factory: 'keystonemiddleware.audit:filter_factory'
          map_file: '/etc/pycadf/cinder_api_audit_map.conf'
      ....
      volume:
        audit:
          enabled: true
      ....
          filter_factory: 'keystonemiddleware.audit:filter_factory'
          map_file: '/etc/pycadf/cinder_api_audit_map.conf'

* Cinder setup with custom availability zones:

  .. code-block:: yaml

    cinder:
      controller:
        default_availability_zone: my-default-zone
        storage_availability_zone: my-custom-zone-name
    cinder:
      volume:
        default_availability_zone: my-default-zone
        storage_availability_zone: my-custom-zone-name

  The ``default_availability_zone`` is used when a volume has been created,
  without specifying a zone in the ``create`` request as this zone must exist
  in your configuration.

  The ``storage_availability_zone`` is an actual zone where the node belongs to
  and must be specified per each node.

* Cinder setup with custom non-admin volume query filters:

  .. code-block:: yaml

    cinder:
      controller:
        query_volume_filters:
          - name
          - status
          - metadata
          - availability_zone
          - bootable

* ``public_endpoint`` and ``osapi_volume_base_url``:

  * ``public_endpoint``
     Used for configuring versions endpoint
  * ``osapi_volume_base_URL``
     Used to present Cinder URL to users

  These parameters can be useful when running Cinder under load balancer in
  SSL.

  .. code-block:: yaml

    cinder:
      controller:
        public_endpoint_address: https://${_param:cluster_domain}:8776

* Client role definition:

  .. code-block:: yaml

    cinder:
      client:
        enabled: true
        identity:
          host: 127.0.0.1
          port: 35357
          project: service
          user: cinder
          password: pwd
          protocol: http
          endpoint_type: internalURL
          region_name: RegionOne
        backend:
          ceph:
            type_name: standard-iops
            engine: ceph
            key:
              conn_speed: fibre-10G

* Barbican integration enablement:

  .. code-block:: yaml

    cinder:
      controller:
        barbican:
          enabled: true

* Keystone API version specification (v3 is default):

  .. code-block:: yaml

    cinder:
      controller:
        identity:
          api_version: v2.0

**Enhanced logging with logging.conf**

By default ``logging.conf`` is disabled.
You can enable per-binary ``logging.conf`` by setting the following
parameters:

* ``openstack_log_appender``
   Set to ``true`` to enable ``log_config_append`` for all OpenStack
   services

* ``openstack_fluentd_handler_enabled``
   Set to ``true`` to enable FluentHandler for all Openstack services

* ``openstack_ossyslog_handler_enabled``
   Set to ``true`` to enable OSSysLogHandler for all Openstack services

Only WatchedFileHandler, OSSysLogHandler, and FluentHandler are available.

To configure this functionality with pillar:

.. code-block:: yaml

  cinder:
    controller:
      logging:
        log_appender: true
        log_handlers:
          watchedfile:
            enabled: true
          fluentd:
            enabled: true
          ossyslog:
            enabled: true

    volume:
      logging:
        log_appender: true
        log_handlers:
          watchedfile:
            enabled: true
          fluentd:
            enabled: true
          ossyslog:
            enabled: true

Enable x509 and ssl communication between Cinder and Galera cluster.
---------------------
By default communication between Cinder and Galera is unsecure.

cinder:
  volume:
    database:
      x509:
        enabled: True
  controller:
    database:
      x509:
        enabled: True

You able to set custom certificates in pillar:

cinder:
  controller:
    database:
      x509:
        cacert: (certificate content)
        cert: (certificate content)
        key: (certificate content)
  volume:
    database:
      x509:
        cacert: (certificate content)
        cert: (certificate content)
        key: (certificate content)
