- 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.

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

Possible values:

List of strings of the following form:
- <a valid directory path>:<optional integer priority>

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

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 trafic 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.

Possible values:

A valid path to a CA file

Related options:

https_insecure

https_insecure¶

Type: boolean
Default: True

Set verification of the remote server certificate.

This configuration option takes in a boolean value to determine whether or not to verify the remote server certificate. If set to True, the remote server certificate is not verified. If the option is set to False, then the default CA truststore is used for verification.

This option is ignored if https_ca_certificates_file is set. The remote server certificate will then be verified using the file specified using the https_ca_certificates_file option.

Possible values:

True
False

Related options:

https_ca_certificates_file

http_proxy_information¶

Type: dict
Default: {}

The http/https proxy information to be used to connect to the remote server.

Provide an integer value representing the size in megabytes to chunk Glance images into. The default chunk size is 8 megabytes. For optimal performance, the value should be a power of two.

When Ceph’s RBD object storage system is used as the storage backend for storing Glance images, the images are chunked into objects of the size set using this option. These chunked objects are then stored across the distributed block data store to use for Glance.

Possible Values:

Any positive integer value

Related options:

None

rbd_store_pool¶

Type: string
Default: images

RADOS pool in which images are stored.

When RBD is used as the storage backend for storing Glance images, the images are stored by means of logical grouping of the objects (chunks of images) into a pool. Each pool is defined with the number of placement groups it can contain. The default pool that is used is ‘images’.

More information on the RBD storage backend can be found here: http://ceph.com/planet/how-data-is-stored-in-ceph-cluster/

Possible Values:

A valid pool name

Related options:

If the value for this option is not set by the user or is set to None, a default value will be chosen, which will be based on the client. section in rbd_store_ceph_conf.

Possible Values:

A valid RADOS user

Related options:

rbd_store_ceph_conf

rbd_store_ceph_conf¶

Type: string
Default: ''

Ceph configuration file path.

This configuration option specifies the path to the Ceph configuration file to be used.

See the Ceph documentation for details.

NOTE: If using Cephx authentication, this file should include a reference to the right keyring in a client.<USER> section

NOTE 2: If you leave this option empty (the default), the actual Ceph configuration file used may change depending on what version of librados is being used. If it is important for you to know exactly which configuration file is in effect, you may specify that file here using this option.

Possible Values:

A valid path to a configuration file

Related options:

rbd_store_user

rados_connect_timeout¶

Type: integer
Default: 0

Timeout value for connecting to Ceph cluster.

This configuration option takes in the timeout value in seconds used when connecting to the Ceph cluster i.e. it sets the time to wait for glance-api before closing the connection. This prevents glance-api hangups during the connection to RBD. If the value for this option is set to less than or equal to 0, no timeout is set and the default librados value is used.

Possible Values:

Any integer value

Related options:

None

rbd_thin_provisioning¶

Type: boolean
Default: False

Default: https://swift.openstack.example.org/v1/path_not_including_container_name

This option has a sample default set, which means that its actual default value may vary from the one documented above.

The URL endpoint to use for Swift backend storage.

Provide a string value representing the URL endpoint to use for storing Glance images in Swift store. By default, an endpoint is not set and the storage URL returned by auth is used. Setting an endpoint with swift_store_endpoint overrides the storage URL and is used for Glance image storage.

NOTE: The URL should include the path up to, but excluding the container. The location of an object is obtained by appending the container and object to the configured URL.

Possible values:

String value representing a valid URL path up to a Swift container

Related Options:

None

swift_store_endpoint_type¶

Type: string
Default: publicURL
Valid Values: publicURL, adminURL, internalURL

Endpoint Type of Swift service.

This string value indicates the endpoint type to use to fetch the Swift endpoint. The endpoint type determines the actions the user will be allowed to perform, for instance, reading and writing to the Store. This setting is only used if swift_store_auth_version is greater than 1.

Possible values:

publicURL
adminURL
internalURL

Related options:

swift_store_endpoint

swift_store_service_type¶

Type: string
Default: object-store

Type of Swift service to use.

Provide a string value representing the service type to use for storing images while using Swift backend storage. The default service type is set to object-store.

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.

Related options:

swift_store_multiple_containers_seed
swift_store_multi_tenant
swift_store_create_container_on_put

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

swift_store_create_container_on_put¶

Type: boolean
Default: False

Create container, if it doesn’t already exist, when uploading image.

At the time of uploading an image, if the corresponding container doesn’t exist, it will be created provided this configuration option is set to True. By default, it won’t be created. This behavior is applicable for both single and multiple containers mode.

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:

A non-negative integer less than or equal to 32

Related options:

swift_store_container
swift_store_multi_tenant

swift_store_admin_tenants¶

Type: list
Default: []

List of tenants that will be granted admin access.

This is a list of tenants that will be granted read/write access on all Swift containers created by Glance in multi-tenant mode. The default value is an empty list.

Possible values:

A comma separated list of strings representing UUIDs of Keystone projects/tenants

Related options:

None

swift_store_ssl_compression¶

Type: boolean
Default: True

SSL layer compression for HTTPS Swift requests.

Provide a boolean value to determine whether or not to compress HTTPS Swift requests for images at the SSL layer. By default, compression is enabled.

When using Swift as the backend store for Glance image storage, SSL layer compression of HTTPS Swift requests can be set using this option. If set to False, SSL layer compression of HTTPS Swift requests is disabled. Disabling this option may improve performance for images which are already in a compressed format, for example, qcow2.

Possible values:

True
False

Related Options:

None

swift_store_retry_get_count¶

Type: integer
Default: 0
Minimum Value: 0

The number of times a Swift download will be retried before the request fails.

Provide an integer value representing the number of times an image download must be retried before erroring out. The default value is zero (no retry on a failed image download). When set to a positive integer value, swift_store_retry_get_count ensures that the download is attempted this many more times upon a download failure before sending an error message.

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

Related options:

swift_upload_buffer_dir

default_swift_reference¶

Type: string
Default: ref1

Reference to default Swift account/backing store parameters.

Provide a string value representing a reference to the default set of parameters required for using swift account/backing store for image storage. The default reference value for this configuration option is ‘ref1’. This configuration option dereferences the parameters and facilitates image storage in Swift storage backend every time a new image is added.

Possible values:

A valid string value

Related options:

None

swift_store_auth_version¶

Type: string
Default: 2

Version of the authentication service to use. Valid versions are 2 and 3 for keystone and 1 (deprecated) for swauth and rackspace.

Type: string
Default: <None>

Absolute path to the file containing the swift account(s) configurations.

Include a string value representing the path to a configuration file that has references for each of the configured Swift account(s)/backing stores. By default, no file path is specified and customized Swift referencing is disabled. Configuring this option is highly recommended while using Swift storage backend for image storage as it avoids storage of credentials in the database.

NOTE: Please do not configure this option if you have set swift_store_multi_tenant to True.

Possible values:

String value representing an absolute path on the glance-api node

Related options:

swift_store_multi_tenant

swift_upload_buffer_dir¶

Type: string
Default: <None>

vmware_datastores¶

Type: multi-valued
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>

keystone_authtoken¶

www_authenticate_uri¶

Type: string
Default: <None>

Complete “public” Identity API endpoint. This endpoint should not be an “admin” endpoint, as it should be accessible by all end users. 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.

service_token_roles¶

Type: list
Default: ['service']

A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token.
