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-config-flags | string

  Comma-separated list of key=value pairs to be added to glance-api.conf where 'value' may itself be a comma-separated list of values to be assigned to the 'key'.

• audit-middleware | boolean

  Enable Keystone auditing middleware for logging API calls.

• bluestore-compression-algorithm | string

  Compressor to use (if any) for pools requested by this charm. . NOTE: The ceph-osd charm sets a global default for this value (defaults to 'lz4' unless configured by the end user) which will be used unless specified for individual pools.

• bluestore-compression-max-blob-size | int

  Chunks larger than this are broken into smaller blobs sizing bluestore compression max blob size before being compressed on pools requested by this charm.

• bluestore-compression-max-blob-size-hdd | int

  Value of bluestore compression max blob size for rotational media on pools requested by this charm.

• bluestore-compression-max-blob-size-ssd | int

  Value of bluestore compression max blob size for solid state media on pools requested by this charm.

• bluestore-compression-min-blob-size | int

  Chunks smaller than this are never compressed on pools requested by this charm.

• bluestore-compression-min-blob-size-hdd | int

  Value of bluestore compression min blob size for rotational media on pools requested by this charm.

• bluestore-compression-min-blob-size-ssd | int

  Value of bluestore compression min blob size for solid state media on pools requested by this charm.

• bluestore-compression-mode | string

  Policy for using compression on pools requested by this charm. . 'none' means never use compression. 'passive' means use compression when clients hint that data is compressible. 'aggressive' means use compression unless clients hint that data is not compressible. 'force' means use compression under all circumstances even if the clients hint that the data is not compressible.

• bluestore-compression-required-ratio | float

  The ratio of the size of the data chunk after compression relative to the original size must be at least this small in order to store the compressed version on pools requested by this charm.

• ceph-osd-replication-count | int

  Default: 3

  This value dictates the number of replicas ceph must make of any object it stores within the images rbd pool. Of course, this only applies if using Ceph as a backend store. Note that once the images rbd pool has been created, changing this value will not have any effect (although it can be changed in ceph by manually configuring your ceph cluster).

• ceph-pool-weight | int

  Default: 5

  Defines a relative weighting of the pool as a percentage of the total amount of data in the Ceph cluster. This effectively weights the number of placement groups for the pool created to be appropriately portioned to the amount of data expected. For example, if the compute images for the OpenStack compute instances are expected to take up 20% of the overall configuration then this value would be specified as 20. Note - it is important to choose an appropriate value for the pool weight as this directly affects the number of placement groups which will be created for the pool. The number of placement groups for a pool can only be increased, never decreased - so it is important to identify the percent of data that will likely reside in the pool.

• cinder-http-retries | int

  Default: 3

  Number of cinderclient retries on failed http calls.

• cinder-state-transition-timeout | int

  Default: 300

  Time period of time in seconds to wait for a cinder volume transition to complete.

• container-formats | string

  Comma separated list of container formats that Glance will support.

• custom-import-properties | string

  Set custom image properties when images are imported using the interoperable image import process. Properties and their value are delimited by commas, and values with colons and spaces are possible. The properties specified here will be added to the glance-api configuration file without being validated. Example: 'prop1:val1,prop2:val-2,prop3:val:with:colons'

• database | string

  Default: glance

  Glance database name.

• database-user | string

  Default: glance

  Database username

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

• ec-profile-crush-locality | string

  (lrc plugin) The type of the crush bucket in which each set of chunks defined by l will be stored. For instance, if it is set to rack, each group of l chunks will be placed in a different rack. It is used to create a CRUSH rule step such as step choose rack. If it is not set, no such grouping is done.

• ec-profile-device-class | string

  Device class from CRUSH map to use for placement groups for erasure profile - valid values: ssd, hdd or nvme (or leave unset to not use a device class).

• ec-profile-durability-estimator | int

  (shec plugin - c) The number of parity chunks each of which includes each data chunk in its calculation range. The number is used as a durability estimator. For instance, if c=2, 2 OSDs can be down without losing data.

• ec-profile-helper-chunks | int

  (clay plugin - d) Number of OSDs requested to send data during recovery of a single chunk. d needs to be chosen such that k+1 <= d <= k+m-1. Larger the d, the better the savings.

• ec-profile-k | int

  Default: 1

  Number of data chunks that will be used for EC data pool. K+M factors should never be greater than the number of available zones (or hosts) for balancing.

• ec-profile-locality | int

  (lrc plugin - l) Group the coding and data chunks into sets of size l. For instance, for k=4 and m=2, when l=3 two groups of three are created. Each set can be recovered without reading chunks from another set. Note that using the lrc plugin does incur more raw storage usage than isa or jerasure in order to reduce the cost of recovery operations.

• ec-profile-m | int

  Default: 2

  Number of coding chunks that will be used for EC data pool. K+M factors should never be greater than the number of available zones (or hosts) for balancing.

• ec-profile-name | string

• ec-rbd-metadata-pool | string

  Name of the metadata pool to be created (for RBD use-cases). If not defined a metadata pool name will be generated based on the name of the data pool used by the application. The metadata pool is always replicated, not erasure coded.

• expose-image-locations | boolean

  Default: True

  Expose underlying image locations via the API. Enabling this is useful especially when using Ceph for image storage. Only disable this option if you do not wish to use copy-on-write clones of RAW format images with Ceph in Cinder and Nova. . NOTE: When S3 backend is enabled, this value will be ignored. The charm will not expose the image location for all backends not to expose S3 credentials.

• filesystem-store-datadir | string

  Default: /var/lib/glance/images/

  Directory to which the filesystem backend store writes images. Upon start up, Glance creates the directory if it doesn’t already exist and verifies write access to the user under which glance-api runs. If the write access isn’t available, a BadStoreConfiguration exception is raised and the filesystem store may not be available for adding new images. NOTE: This directory is used only when filesystem store is used as a storage backend.

If no units provided, bytes are assumed. . WARNING: this value should only be increased after careful consideration and must be set to a value under 8EB (9223372036854775808 bytes).

• 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.
