Cinder

Learn about configurations >

• action-managed-upgrade | boolean

  If True enables openstack upgrades for this charm via juju actions. You will still need to set openstack-origin to the new repository but instead of an upgrade running automatically across all units, it will wait for you to execute the openstack-upgrade action for this charm on each unit. If False it will revert to existing behavior of upgrading all units on config change.

• api-listening-port | int

  Default: 8776

  OpenStack Volume API listening port.

• audit-middleware | boolean

  Enable Keystone auditing middleware for logging API calls.

• block-device | string

  Default: sdb

  Set to 'None' for deployments whose storage is managed by separate charms (cinder-lvm, cinder-netapp, ceph-mon). . The below LVM functionality is DEPRECATED. Use the cinder-lvm charm instead. . The block devices on which to create LVM volume group. . This can also be a space-delimited list of block devices to attempt to use in the cinder LVM volume group - each block device detected will be added to the available physical volumes in the volume group. . May be set to the path and size of a local file (/path/to/file.img|$sizeG), which will be created and used as a loopback device (for testing only). $sizeG defaults to 5G

• ceph-osd-replication-count | int

  Default: 3

  This value dictates the number of replicas ceph must make of any object it stores within the cinder rbd pool. Of course, this only applies if using Ceph as a backend store. Note that once the cinder rbd pool has been created, changing this value will not have any effect (although the configuration of a pool can be always be changed within ceph itself or via the charm used to deploy ceph).

• config-flags | string

  Comma-separated list of key=value config flags. These values will be placed in the cinder.conf [DEFAULT] section.

• database | string

  Default: cinder

  Database to request access.

• database-user | string

  Default: cinder

  Username to request database access.

• debug | boolean

  Enable debug logging.

• default-volume-type | string

  The default volume type when creating a new volume without a volume type specified. It's useful only when multiple storage backends to be connected to Cinder. The corresponding volume type must be created after a deployment via API to take effect, e.g., openstack volume type create VOLUME_TYPE --property volume_backend_name=BACKEND_NAME

• dns-ha | boolean

  Use DNS HA with MAAS 2.0. Note if this is set do not set vip settings below.

• enabled-services | string

  Default: all

  If splitting cinder services between units, define which services to install and configure.

• ephemeral-unmount | string

  The below LVM functionality is DEPRECATED. Use the cinder-lvm charm instead. . Cloud instances provide ephemeral storage which is normally mounted on /mnt. . Providing this option will force an unmount of the ephemeral device so that it can be used as a Cinder storage device. This is useful for testing purposes (cloud deployment is not a typical use case).

• glance-api-version | int

  Default: 1

  Newer storage drivers may require the v2 Glance API to perform certain actions e.g. the RBD driver requires requires this to support COW cloning of images. This option will default to v1 for backwards compatibility with older glance services.

• image-volume-cache-max-size-gb | int

  Max size of the image volume cache in GB. 0 means unlimited. Supported on OpenStack Ocata and newer.

• nagios_context | string

  Default: juju

  Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like 'juju-myservice-0'. If you are running multiple environments with the same services in them this allows you to differentiate between them.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup

NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade unless action-managed-upgrade is set to True.

• os-admin-hostname | string

  The hostname or address of the admin endpoints created for cinder in the keystone identity provider. . This value will be used for admin endpoints. For example, an os-admin-hostname set to 'cinder.admin.example.com' with ssl enabled will create two admin endpoints for cinder: . https://cinder.admin.example.com:443/v2/$(tenant_id)s and https://cinder.admin.example.com:443/v3/$(tenant_id)s

• overwrite | string

  Default: false

  The below LVM functionality is DEPRECATED. Use the cinder-lvm charm instead. . If true, charm will attempt to overwrite block devices containing previous filesystems or LVM, assuming it is not in use.

• prefer-ipv6 | boolean

  If True enables IPv6 support. The charm will expect network interfaces to be configured with an IPv6 address. If set to False (default) IPv4 is expected. .

• ssl_key | string

  SSL key to use with certificate specified as ssl_cert.

• use-internal-endpoints | boolean

  Openstack mostly defaults to using public endpoints for internal communication between services. If set to True this option will configure services to use internal endpoints where possible.

• use-policyd-override | boolean

  If True then use the resource file named 'policyd-override' to install override YAML files in the service's policy.d directory. The resource file should be a ZIP file containing at least one yaml file with a .yaml or .yml extension. If False then remove the overrides.
