glance-cache.conf

DEFAULT

allow_additional_image_properties
Type:boolean
Default:true

Allow users to add additional/custom properties to images. Glance defines a standard set of properties (in its schema) that appear on every image. These properties are also known as base properties. In addition to these properties, Glance allows users to add custom properties to images. These are known as additional properties. By default, this configuration option is set to True and users are allowed to add additional properties. The number of additional properties that can be added to an image can be controlled via image_property_quota configuration option. Possible values: * True * False Related options: * image_property_quota

image_member_quota
Type:integer
Default:128

Maximum number of image members per image. This limits the maximum of users an image can be shared with. Any negative value is interpreted as unlimited. Related options: * None

image_property_quota
Type:integer
Default:128

Maximum number of properties allowed on an image. This enforces an upper limit on the number of additional properties an image can have. Any negative value is interpreted as unlimited. NOTE: This won’t have any impact if additional properties are disabled. Please refer to allow_additional_image_properties. Related options: * allow_additional_image_properties

image_tag_quota
Type:integer
Default:128

Maximum number of tags allowed on an image. Any negative value is interpreted as unlimited. Related options: * None

image_location_quota
Type:integer
Default:10

Maximum number of locations allowed on an image. Any negative value is interpreted as unlimited. Related options: * None

data_api
Type:string
Default:glance.db.sqlalchemy.api

Python module path of data access API. Specifies the path to the API to use for accessing the data model. This option determines how the image catalog data will be accessed. Possible values: * glance.db.sqlalchemy.api * glance.db.registry.api * glance.db.simple.api If this option is set to glance.db.sqlalchemy.api then the image catalog data is stored in and read from the database via the SQLAlchemy Core and ORM APIs. Setting this option to glance.db.registry.api will force all database access requests to be routed through the Registry service. This avoids data access from the Glance API nodes for an added layer of security, scalability and manageability. NOTE: In v2 OpenStack Images API, the registry service is optional. In order to use the Registry API in v2, the option enable_v2_registry must be set to True. Finally, when this configuration option is set to glance.db.simple.api, image catalog data is stored in and read from an in-memory data structure. This is primarily used for testing. Related options: * enable_v2_api * enable_v2_registry

limit_param_default
Type:integer
Default:25
Minimum Value:1

The default number of results to return for a request. Responses to certain API requests, like list images, may return multiple items. The number of results returned can be explicitly controlled by specifying the limit parameter in the API request. However, if a limit parameter is not specified, this configuration value will be used as the default number of results to be returned for any API request. NOTES: * The value of this configuration option may not be greater than the value specified by api_limit_max. * Setting this to a very large value may slow down database queries and increase response times. Setting this to a very low value may result in poor user experience. Possible values: * Any positive integer Related options: * api_limit_max

api_limit_max
Type:integer
Default:1000
Minimum Value:1

Maximum number of results that could be returned by a request. As described in the help text of limit_param_default, some requests may return multiple results. The number of results to be returned are governed either by the limit parameter in the request or the limit_param_default configuration option. The value in either case, can’t be greater than the absolute maximum defined by this configuration option. Anything greater than this value is trimmed down to the maximum value defined here. NOTE: Setting this to a very large value may slow down database queries and increase response times. Setting this to a very low value may result in poor user experience. Possible values: * Any positive integer Related options: * limit_param_default

show_image_direct_url
Type:boolean
Default:false

Show direct image location when returning an image. This configuration option indicates whether to show the direct image location when returning image details to the user. The direct image location is where the image data is stored in backend storage. This image location is shown under the image property direct_url. When multiple image locations exist for an image, the best location is displayed based on the location strategy indicated by the configuration option location_strategy. NOTES: * Revealing image locations can present a GRAVE SECURITY RISK as image locations can sometimes include credentials. Hence, this is set to False by default. Set this to True with EXTREME CAUTION and ONLY IF you know what you are doing! * If an operator wishes to avoid showing any image location(s) to the user, then both this option and show_multiple_locations MUST be set to False. Possible values: * True * False Related options: * show_multiple_locations * location_strategy

show_multiple_locations
Type:boolean
Default:false

Show all image locations when returning an image. This configuration option indicates whether to show all the image locations when returning image details to the user. When multiple image locations exist for an image, the locations are ordered based on the location strategy indicated by the configuration opt location_strategy. The image locations are shown under the image property locations. NOTES: * Revealing image locations can present a GRAVE SECURITY RISK as image locations can sometimes include credentials. Hence, this is set to False by default. Set this to True with EXTREME CAUTION and ONLY IF you know what you are doing! * If an operator wishes to avoid showing any image location(s) to the user, then both this option and show_image_direct_url MUST be set to False. Possible values: * True * False Related options: * show_image_direct_url * location_strategy

Warning

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

Reason:This option will be removed in the Pike release or later because the same functionality can be achieved with greater granularity by using policies. Please see the Newton release notes for more information.
image_size_cap
Type:integer
Default:1099511627776
Minimum Value:1
Maximum Value:9223372036854775808

Maximum size of image a user can upload in bytes. An image upload greater than the size mentioned here would result in an image creation failure. This configuration option defaults to 1099511627776 bytes (1 TiB). NOTES: * This value should only be increased after careful consideration and must be set less than or equal to 8 EiB (9223372036854775808). * This value must be set with careful consideration of the backend storage capacity. Setting this to a very low value may result in a large number of image failures. And, setting this to a very large value may result in faster consumption of storage. Hence, this must be set according to the nature of images created and storage capacity available. Possible values: * Any positive number less than or equal to 9223372036854775808

user_storage_quota
Type:string
Default:0

Maximum amount of image storage per tenant. This enforces an upper limit on the cumulative storage consumed by all images of a tenant across all stores. This is a per-tenant limit. The default unit for this configuration option is Bytes. However, storage units can be specified using case-sensitive literals B, KB, MB, GB and TB representing Bytes, KiloBytes, MegaBytes, GigaBytes and TeraBytes respectively. Note that there should not be any space between the value and unit. Value 0 signifies no quota enforcement. Negative values are invalid and result in errors. Possible values: * A string that is a valid concatenation of a non-negative integer representing the storage value and an optional string literal representing storage units as mentioned above. Related options: * None

enable_v1_api
Type:boolean
Default:true

Deploy the v1 OpenStack Images API. When this option is set to True, Glance service will respond to requests on registered endpoints conforming to the v1 OpenStack Images API. NOTES: * If this option is enabled, then enable_v1_registry must also be set to True to enable mandatory usage of Registry service with v1 API. * If this option is disabled, then the enable_v1_registry option, which is enabled by default, is also recommended to be disabled. * This option is separate from enable_v2_api, both v1 and v2 OpenStack Images API can be deployed independent of each other. * If deploying only the v2 Images API, this option, which is enabled by default, should be disabled. Possible values: * True * False Related options: * enable_v1_registry * enable_v2_api

enable_v2_api
Type:boolean
Default:true

Deploy the v2 OpenStack Images API. When this option is set to True, Glance service will respond to requests on registered endpoints conforming to the v2 OpenStack Images API. NOTES: * If this option is disabled, then the enable_v2_registry option, which is enabled by default, is also recommended to be disabled. * This option is separate from enable_v1_api, both v1 and v2 OpenStack Images API can be deployed independent of each other. * If deploying only the v1 Images API, this option, which is enabled by default, should be disabled. Possible values: * True * False Related options: * enable_v2_registry * enable_v1_api

enable_v1_registry
Type:boolean
Default:true

Deploy the v1 API Registry service. When this option is set to True, the Registry service will be enabled in Glance for v1 API requests. NOTES: * Use of Registry is mandatory in v1 API, so this option must be set to True if the enable_v1_api option is enabled. * If deploying only the v2 OpenStack Images API, this option, which is enabled by default, should be disabled. Possible values: * True * False Related options: * enable_v1_api

enable_v2_registry
Type:boolean
Default:true

Deploy the v2 API Registry service. When this option is set to True, the Registry service will be enabled in Glance for v2 API requests. NOTES: * Use of Registry is optional in v2 API, so this option must only be enabled if both enable_v2_api is set to True and the data_api option is set to glance.db.registry.api. * If deploying only the v1 OpenStack Images API, this option, which is enabled by default, should be disabled. Possible values: * True * False Related options: * enable_v2_api * data_api

pydev_worker_debug_host
Type:host address
Default:localhost

Host address of the pydev server. Provide a string value representing the hostname or IP of the pydev server to use for debugging. The pydev server listens for debug connections on this address, facilitating remote debugging in Glance. Possible values: * Valid hostname * Valid IP address Related options: * None

pydev_worker_debug_port
Type:port number
Default:5678
Minimum Value:0
Maximum Value:65535

Port number that the pydev server will listen on. Provide a port number to bind the pydev server to. The pydev process accepts debug connections on this port and facilitates remote debugging in Glance. Possible values: * A valid port number Related options: * None

metadata_encryption_key
Type:string
Default:<None>

AES key for encrypting store location metadata. Provide a string value representing the AES cipher to use for encrypting Glance store metadata.

Type:string
Default:sha256

Digest algorithm to use for digital signature. Provide a string value representing the digest algorithm to use for generating digital signatures. By default, sha256 is used. To get a list of the available algorithms supported by the version of OpenSSL on your platform, run the command: openssl list-message-digest-algorithms. Examples are ‘sha1’, ‘sha256’, and ‘sha512’. NOTE: digest_algorithm is not related to Glance’s image signing and verification. It is only used to sign the universally unique identifier (UUID) as a part of the certificate file and key file validation. Possible values: * An OpenSSL message digest algorithm identifier Relation options: * None

node_staging_uri
Type:string
Default:file:///tmp/staging/

The URL provides location where the temporary data will be stored This option is for Glance internal use only. Glance will save the image data uploaded by the user to ‘staging’ endpoint during the image import process. This option does not change the ‘staging’ API endpoint by any means. NOTE: It is discouraged to use same path as [TASKS]/work_dir NOTE: ‘file://<absolute-directory-path>’ is the only option api_image_import flow will support for now. NOTE: The staging path must be on shared filesystem available to all Glance API nodes. Possible values: * String starting with ‘file://’ followed by absolute FS path Related options: * [TASKS]/work_dir * [DEFAULT]/enable_image_import (deprecated)

enable_image_import
Type:boolean
Default:false

Enables the Image Import workflow introduced in Pike As ‘[DEFAULT]/node_staging_uri’ is required for the Image Import, it’s disabled per default in Pike, enabled per default in Queens and removed in Rocky. This allows Glance to operate with previous version configs upon upgrade. Setting this option to True will enable the endpoints related to Image Import Refactoring work. Related options: * [DEFUALT]/node_staging_uri

Warning

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

Reason: This option is deprecated for removal in Rocky. It was introduced to make sure that the API is not enabled before the ‘[DEFAULT]/node_staging_uri’ is defined and is long term redundant.
image_cache_sqlite_db
Type:string
Default:cache.db

The relative path to sqlite file database that will be used for image cache management. This is a relative path to the sqlite file database that tracks the age and usage statistics of image cache. The path is relative to image cache base directory, specified by the configuration option image_cache_dir. This is a lightweight database with just one table. Possible values: * A valid relative path to sqlite file database Related options: * image_cache_dir

image_cache_driver
Type:string
Default:sqlite
Valid Values:sqlite, xattr

The driver to use for image cache management. This configuration option provides the flexibility to choose between the different image-cache drivers available. An image-cache driver is responsible for providing the essential functions of image-cache like write images to/read images from cache, track age and usage of cached images, provide a list of cached images, fetch size of the cache, queue images for caching and clean up the cache, etc. The essential functions of a driver are defined in the base class glance.image_cache.drivers.base.Driver. All image-cache drivers (existing and prospective) must implement this interface. Currently available drivers are sqlite and xattr. These drivers primarily differ in the way they store the information about cached images: * The sqlite driver uses a sqlite database (which sits on every glance node locally) to track the usage of cached images. * The xattr driver uses the extended attributes of files to store this information. It also requires a filesystem that sets atime on the files when accessed. Possible values: * sqlite * xattr Related options: * None

image_cache_max_size
Type:integer
Default:10737418240
Minimum Value:0

The upper limit on cache size, in bytes, after which the cache-pruner cleans up the image cache. NOTE: This is just a threshold for cache-pruner to act upon. It is NOT a hard limit beyond which the image cache would never grow. In fact, depending on how often the cache-pruner runs and how quickly the cache fills, the image cache can far exceed the size specified here very easily. Hence, care must be taken to appropriately schedule the cache-pruner and in setting this limit. Glance caches an image when it is downloaded. Consequently, the size of the image cache grows over time as the number of downloads increases. To keep the cache size from becoming unmanageable, it is recommended to run the cache-pruner as a periodic task. When the cache pruner is kicked off, it compares the current size of image cache and triggers a cleanup if the image cache grew beyond the size specified here. After the cleanup, the size of cache is less than or equal to size specified here. Possible values: * Any non-negative integer Related options: * None

image_cache_stall_time
Type:integer
Default:86400
Minimum Value:0

The amount of time, in seconds, an incomplete image remains in the cache. Incomplete images are images for which download is in progress. Please see the description of configuration option image_cache_dir for more detail. Sometimes, due to various reasons, it is possible the download may hang and the incompletely downloaded image remains in the incomplete directory. This configuration option sets a time limit on how long the incomplete images should remain in the incomplete directory before they are cleaned up. Once an incomplete image spends more time than is specified here, it’ll be removed by cache-cleaner on its next run. It is recommended to run cache-cleaner as a periodic task on the Glance API nodes to keep the incomplete images from occupying disk space. Possible values: * Any non-negative integer Related options: * None

image_cache_dir
Type:string
Default:<None>

Base directory for image cache. This is the location where image data is cached and served out of. All cached images are stored directly under this directory. This directory also contains three subdirectories, namely, incomplete, invalid and queue. The incomplete subdirectory is the staging area for downloading images. An image is first downloaded to this directory. When the image download is successful it is moved to the base directory. However, if the download fails, the partially downloaded image file is moved to the invalid subdirectory. The queue``subdirectory is used for queuing images for download. This is   used primarily by the cache-prefetcher, which can be scheduled as a periodic   task like cache-pruner and cache-cleaner, to cache images ahead of their usage.   Upon receiving the request to cache an image, Glance touches a file in the   ``queue directory with the image id as the file name. The cache-prefetcher, when running, polls for the files in queue directory and starts downloading them in the order they were created. When the download is successful, the zero-sized file is deleted from the queue directory. If the download fails, the zero-sized file remains and it’ll be retried the next time cache-prefetcher runs. Possible values: * A valid path Related options: * image_cache_sqlite_db

Also include the CA file and cert file using the options registry_client_ca_file and registry_client_cert_file respectively. Possible values: * http * https Related options: * registry_client_key_file * registry_client_cert_file * registry_client_ca_file

registry_client_key_file
Type:string
Default:/etc/ssl/key/key-file.pem

This option is ignored if the registry_client_insecure option is set to True. Possible values: * String value representing a valid absolute path to the CA file. Related options: * registry_client_protocol * registry_client_insecure

registry_client_insecure
Type:boolean
Default:false

Set verification of the registry server certificate. Provide a boolean value to determine whether or not to validate SSL connections to the registry server. By default, this option is set to False and the SSL connections are validated. If set to True, the connection to the registry server is not validated via a certifying authority and the registry_client_ca_file option is ignored. This is the registry’s equivalent of specifying –insecure on the command line using glanceclient for the API. Possible values: * True * False Related options: * registry_client_protocol * registry_client_ca_file

registry_client_timeout
Type:integer
Default:600
Minimum Value:0

Timeout value for registry requests. Provide an integer value representing the period of time in seconds that the API server will wait for a registry request to complete. The default value is 600 seconds. A value of 0 implies that a request will never timeout. Possible values: * Zero * Positive integer Related options: * None

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

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.

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

default_swift_reference
Type:string
Default:ref1

Reference to default Swift account/backing store parameters.

vmware_api_retry_count
Type:integer
Default:10
Minimum Value:1

The number of VMware API retries. This configuration option specifies the number of times the VMware ESX/VC server API must be retried upon connection related issues or server API call overload. It is not possible to specify ‘retry forever’. Possible Values: * Any positive integer value Related options: * None

vmware_task_poll_interval
Type:integer
Default:5
Minimum Value:1

Interval in seconds used for polling remote tasks invoked on VMware ESX/VC server. This configuration option takes in the sleep time in seconds for polling an on-going async task as part of the VMWare ESX/VC server API call. Possible Values: * Any positive integer value Related options: * None

vmware_store_image_dir
Type:string
Default:/openstack_glance

The directory where the glance images will be stored in the datastore. This configuration option specifies the path to the directory where the glance images will be stored in the VMware datastore. If this option is not set, the default directory where the glance images are stored is openstack_glance. Possible Values: * Any string that is a valid path to a directory Related options: * None

vmware_insecure
Type:boolean
Default:false

Set verification of the ESX/vCenter server certificate. This configuration option takes a boolean value to determine whether or not to verify the ESX/vCenter server certificate. If this option is set to True, the ESX/vCenter server certificate is not verified. If this option is set to False, then the default CA truststore is used for verification. This option is ignored if the “vmware_ca_file” option is set. In that case, the ESX/vCenter server certificate will then be verified using the file specified using the “vmware_ca_file” option . Possible Values: * True * False Related options: * vmware_ca_file

glance_store vmware_api_insecure
vmware_ca_file
Type:string
Default:/etc/ssl/certs/ca-certificates.crt

Absolute path to the CA bundle file. This configuration option enables the operator to use a custom Cerificate Authority File to verify the ESX/vCenter certificate. If this option is set, the “vmware_insecure” option will be ignored and the CA file specified will be used to authenticate the ESX/vCenter server certificate and establish a secure connection to the server. Possible Values: * Any string that is a valid absolute path to a CA file Related options: * vmware_insecure

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> Related options: * None
