- 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, aBadStoreConfiguration
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
orfilesystem_store_datadirs
option must be specified inglance-api.conf
. If both options are specified, aBadStoreConfiguration
will be raised and the filesystem store may not be available for adding new images.- Possible values:

- 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
orfilesystem_store_datadirs
option must be specified inglance-api.conf
. If both options are specified, aBadStoreConfiguration
will be raised and the filesystem store may not be available for adding new images.- Possible values:

The file must contain a valid JSON object. The object should contain the keys
id
andmountpoint
. 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:

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. If this option is set, the
https_insecure
option will be ignored and the CA file specified will be used to authenticate the server certificate and establish a secure connection to the server.- 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 thehttps_ca_certificates_file
option.- Possible values:

- Minimum Value
1
Size, in megabytes, to chunk RADOS images into.
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/

- 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 UUIDfdae39a1-bac5-4238-aba4-69bcc726e848
would be placed in the containerglance_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 beglance_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_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.

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 andswift_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:

- 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.htmlNOTE: This is used only when swift_store_multi_tenant is disabled.

- 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 toTrue``(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
