  • A comma separated list that could include:

    • file

    • http

    • swift

    • rbd

    • cinder

    • vmware

    • s3

Related Options:

  • default_store

Warning

This option is deprecated for removal since Rocky. Its value may be silently ignored in the future.

Reason:

This option is deprecated against new config option enabled_backends which helps to configure multiple backend stores of different schemes. This option is scheduled for removal in the U development cycle.

default_store
Type:

string

Default:

file

Valid Values:

file, filesystem, http, https, swift, swift+http, swift+https, swift+config, rbd, cinder, vsphere, s3

The default scheme to use for storing images.

Provide a string value representing the default scheme to use for storing images. If not set, Glance uses file as the default scheme to store images with the file store.

NOTE: The value given for this configuration option must be a valid scheme for a store registered with the stores configuration option.

Possible values:

  • file

  • filesystem

  • http

  • https

  • swift

  • swift+http

  • swift+https

  • swift+config

  • rbd

  • cinder

  • vsphere

  • s3

Related Options:

  • stores

Warning

This option is deprecated for removal since Rocky. Its value may be silently ignored in the future.

Reason:

This option is deprecated against new config option default_backend which acts similar to default_store config option. This option is scheduled for removal in the U development cycle.

filesystem_store_datadir
Type:

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. Either filesystem_store_datadir or filesystem_store_datadirs option must be specified in glance-api.conf. If both options are specified, a BadStoreConfiguration will be raised and the filesystem store may not be available for adding new images.

Possible values:

  • A valid path to a directory

Related options:

  • filesystem_store_datadirs

  • filesystem_store_file_perm

filesystem_store_datadirs
Type:

multi-valued

Default:

''

List of directories and their priorities to which the filesystem backend store writes images.

The filesystem store can be configured to store images in multiple directories as opposed to using a single directory specified by the filesystem_store_datadir configuration option. When using multiple directories, each directory can be given an optional priority to specify the preference order in which they should be used. Priority is an integer that is concatenated to the directory path with a colon where a higher value indicates higher priority. When two directories have the same priority, the directory with most free space is used. When no priority is specified, it defaults to zero.

More information on configuring filesystem store with multiple store directories can be found at https://docs.openstack.org/glance/latest/configuration/configuring.html

NOTE: This directory is used only when filesystem store is used as a storage backend. Either filesystem_store_datadir or filesystem_store_datadirs option must be specified in glance-api.conf. If both options are specified, a BadStoreConfiguration will be raised and the filesystem store may not be available for adding new images.

Possible values:
  • List of strings of the following form:

    • <a valid directory path>:<optional integer priority>

Related options:

  • filesystem_store_datadir

  • filesystem_store_file_perm

filesystem_store_metadata_file
Type:

string

Default:

<None>

Filesystem store metadata file.

The path to a file which contains the metadata to be returned with any location associated with the filesystem store. Once this option is set, it is used for new images created afterward only - previously existing images are not affected.

The file must contain a valid JSON object. The object should contain the keys id and mountpoint. The value for both keys should be a string.

Possible values:

  • A valid path to the store metadata file

Related options:

  • None

filesystem_store_file_perm
Type:

integer

Default:

0

File access permissions for the image files.

Set the intended file access permissions for image data. This provides a way to enable other services, e.g. Nova, to consume images directly from the filesystem store. The users running the services that are intended to be given access to could be made a member of the group that owns the files created. Assigning a value less then or equal to zero for this configuration option signifies that no changes be made to the default permissions. This value will be decoded as an octal digit.

For more information, please refer the documentation at https://docs.openstack.org/glance/latest/configuration/configuring.html

Possible values:

  • A valid file access permission

  • Zero

  • Any negative integer

Related options:

  • None

filesystem_store_chunk_size
Type:

integer

Default:

65536

Minimum Value:

1

Chunk size, in bytes.

The chunk size used when reading or writing image files. Raising this value may improve the throughput but it may also slightly increase the memory usage when handling a large number of requests.

Possible Values:

  • Any positive integer value

Related options:

  • None

filesystem_thin_provisioning
Type:

boolean

Default:

False

Enable or not thin provisioning in this backend.

This configuration option enable the feature of not really write null byte sequences on the filesystem, the holes who can appear will automatically be interpreted by the filesystem as null bytes, and do not really consume your storage. Enabling this feature will also speed up image upload and save network traffic in addition to save space in the backend, as null bytes sequences are not sent over the network.

Possible Values:

  • True

  • False

Related options:

  • None

https_ca_certificates_file
Type:

string

Default:

<None>

Path to the CA bundle file.

This configuration option enables the operator to use a custom Certificate Authority file to verify the remote server certificate.

NOTE: If swift_store_auth_version is set to 2, the value for this configuration option needs to be object-store. If using a higher version of Keystone or a different auth scheme, this option may be modified.

Possible values:

  • A string representing a valid service type for Swift storage.

Related Options:

  • None

swift_store_container
Type:

string

Default:

glance

Name of single container to store images/name prefix for multiple containers

When a single container is being used to store images, this configuration option indicates the container within the Glance account to be used for storing all images. When multiple containers are used to store images, this will be the name prefix for all containers. Usage of single/multiple containers can be controlled using the configuration option swift_store_multiple_containers_seed.

When using multiple containers, the containers will be named after the value set for this configuration option with the first N chars of the image UUID as the suffix delimited by an underscore (where N is specified by swift_store_multiple_containers_seed).

Example: if the seed is set to 3 and swift_store_container = glance, then an image with UUID fdae39a1-bac5-4238-aba4-69bcc726e848 would be placed in the container glance_fda. All dashes in the UUID are included when creating the container name but do not count toward the character limit, so when N=10 the container name would be glance_fdae39a1-ba.

Possible values:

  • If using single container, this configuration option can be any string that is a valid swift container name in Glance’s Swift account

  • If using multiple containers, this configuration option can be any string as long as it satisfies the container naming rules enforced by Swift. The value of swift_store_multiple_containers_seed should be taken into account as well.

swift_store_large_object_size
Type:

integer

Default:

5120

Minimum Value:

1

The size threshold, in MB, after which Glance will start segmenting image data.

Swift has an upper limit on the size of a single uploaded object. By default, this is 5GB. To upload objects bigger than this limit, objects are segmented into multiple smaller objects that are tied together with a manifest file. For more detail, refer to https://docs.openstack.org/swift/latest/overview_large_objects.html

This configuration option specifies the size threshold over which the Swift driver will start segmenting image data into multiple smaller files. Currently, the Swift driver only supports creating Dynamic Large Objects.

NOTE: This should be set by taking into account the large object limit enforced by the Swift cluster in consideration.

Possible values:

  • A positive integer that is less than or equal to the large object limit enforced by the Swift cluster in consideration.

Related options:

  • swift_store_large_object_chunk_size

swift_store_large_object_chunk_size
Type:

integer

Default:

200

Minimum Value:

1

The maximum size, in MB, of the segments when image data is segmented.

When image data is segmented to upload images that are larger than the limit enforced by the Swift cluster, image data is broken into segments that are no bigger than the size specified by this configuration option. Refer to swift_store_large_object_size for more detail.

For example: if swift_store_large_object_size is 5GB and swift_store_large_object_chunk_size is 1GB, an image of size 6.2GB will be segmented into 7 segments where the first six segments will be 1GB in size and the seventh segment will be 0.2GB.

Possible values:

  • A positive integer that is less than or equal to the large object limit enforced by Swift cluster in consideration.

Related options:

  • swift_store_large_object_size

Possible values:

  • True

  • False

Related options:

  • None

swift_store_multi_tenant
Type:

boolean

Default:

False

Store images in tenant’s Swift account.

This enables multi-tenant storage mode which causes Glance images to be stored in tenant specific Swift accounts. If this is disabled, Glance stores all images in its own account. More details multi-tenant store can be found at https://wiki.openstack.org/wiki/GlanceSwiftTenantSpecificStorage

NOTE: If using multi-tenant swift store, please make sure that you do not set a swift configuration file with the ‘swift_store_config_file’ option.

Possible values:

  • True

  • False

Related options:

  • swift_store_config_file

swift_store_multiple_containers_seed
Type:

integer

Default:

0

Minimum Value:

0

Maximum Value:

32

Seed indicating the number of containers to use for storing images.

When using a single-tenant store, images can be stored in one or more than one containers. When set to 0, all images will be stored in one single container. When set to an integer value between 1 and 32, multiple containers will be used to store images. This configuration option will determine how many containers are created. The total number of containers that will be used is equal to 16^N, so if this config option is set to 2, then 16^2=256 containers will be used to store images.

Please refer to swift_store_container for more detail on the naming convention. More detail about using multiple containers can be found at https://specs.openstack.org/openstack/glance-specs/specs/kilo/swift-store-multiple-containers.html

NOTE: This is used only when swift_store_multi_tenant is disabled.

Possible values:

  • Zero

  • Positive integer value

Related Options:

  • None

swift_store_expire_soon_interval
Type:

integer

Default:

60

Minimum Value:

0

Time in seconds defining the size of the window in which a new token may be requested before the current token is due to expire.

Typically, the Swift storage driver fetches a new token upon the expiration of the current token to ensure continued access to Swift. However, some Swift transactions (like uploading image segments) may not recover well if the token expires on the fly.

Hence, by fetching a new token before the current token expiration, we make sure that the token does not expire or is close to expiry before a transaction is attempted. By default, the Swift storage driver requests for a new token 60 seconds or less before the current token expiration.

Possible values:

  • Zero

  • Positive integer value

Related Options:

  • None

swift_store_use_trusts
Type:

boolean

Default:

True

Use trusts for multi-tenant Swift store.

This option instructs the Swift store to create a trust for each add/get request when the multi-tenant store is in use. Using trusts allows the Swift store to avoid problems that can be caused by an authentication token expiring during the upload or download of data.

By default, swift_store_use_trusts is set to True``(use of trusts is enabled). If set to ``False, a user token is used for the Swift connection instead, eliminating the overhead of trust creation.

NOTE: This option is considered only when swift_store_multi_tenant is set to True

Possible values:

  • True

  • False

Related options:

  • swift_store_multi_tenant

swift_buffer_on_upload
Type:

boolean

Default:

False

Buffer image segments before upload to Swift.

Provide a boolean value to indicate whether or not Glance should buffer image data to disk while uploading to swift. This enables Glance to resume uploads on error.

NOTES: When enabling this option, one should take great care as this increases disk usage on the API node. Be aware that depending upon how the file system is configured, the disk space used for buffering may decrease the actual disk space available for the glance image cache. Disk utilization will cap according to the following equation: (swift_store_large_object_chunk_size * workers * 1000)

Possible values:

  • True

  • False

Default:

''

The datastores where the image can be stored.

This configuration option specifies the datastores where the image can be stored in the VMWare store backend. This option may be specified multiple times for specifying multiple datastores. The datastore name should be specified after its datacenter path, separated by “:”. An optional weight may be given after the datastore name, separated again by “:” to specify the priority. Thus, the required format becomes <datacenter_path>:<datastore_name>:<optional_weight>.

When adding an image, the datastore with highest weight will be selected, unless there is not enough free space available in cases where the image size is already known. If no weight is given, it is assumed to be zero and the directory will be considered for selection last. If multiple datastores have the same weight, then the one with the most free space available is selected.

Possible Values:

  • Any string of the format: <datacenter_path>:<datastore_name>:<optional_weight>

Related options:

  • None

Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies. If you’re using a versioned v2 endpoint here, then this should not be the same endpoint the service user utilizes for validating tokens, because normal end users may not be able to reach that endpoint. This option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

Try to use HA queues in RabbitMQ (x-ha-policy: all). If you change this option, you must wipe the RabbitMQ database. In RabbitMQ 3.0, queue mirroring is no longer controlled by the x-ha-policy argument when declaring a queue. If you just want to make sure that all queues (except those with auto-generated names) are mirrored across all nodes, run: “rabbitmqctl set_policy HA ‘^(?!amq.).*’ ‘{“ha-mode”: “all”}’ “

Use quorum queues in RabbitMQ (x-queue-type: quorum). The quorum queue is a modern queue type for RabbitMQ implementing a durable, replicated FIFO queue based on the Raft consensus algorithm. It is available as of RabbitMQ 3.8.0. If set this option will conflict with the HA queues (rabbit_ha_queues) aka mirrored queues, in other words the HA queues should be disabled. Quorum queues are also durable by default so the amqp_durable_queues option is ignored when this option is enabled.

rabbit_transient_quorum_queue

Positive integer representing duration in seconds for queue TTL (x-expires). Queues which are unused for the duration of the TTL are automatically deleted. The parameter affects only reply and fanout queues. Setting 0 as value will disable the x-expires. If doing so, make sure you have a rabbitmq policy to delete the queues or you deployment will create an infinite number of queue over time.In case rabbit_stream_fanout is set to True, this option will control data retention policy (x-max-age) for messages in the fanout queue rather then the queue duration itself. So the oldest data in the stream queue will be discarded from it once reaching TTL Setting to 0 will disable x-max-age for stream which make stream grow indefinitely filling up the diskspace

This option controls whether or not to enforce scope when evaluating policies. If True, the scope of the token used in the request is compared to the scope_types of the policy being enforced. If the scopes do not match, an InvalidScope exception will be raised. If False, a message will be logged informing operators that policies are being invoked with mismatching scope.

Warning

This option is deprecated for removal. Its value may be silently ignored in the future.

Reason:

This configuration was added temporarily to facilitate a smooth transition to the new RBAC. OpenStack will always enforce scope checks. This configuration option is deprecated and will be removed in the 2025.2 cycle.

enforce_new_defaults
Type:

boolean

Default:

False

This option controls whether or not to use old deprecated defaults when evaluating policies. If True, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with the enforce_scope flag so that you can get the benefits of new defaults and scope_type together. If False, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.
