Glance Sample Configuration¶
The following are sample configuration files for all Glance services and utilities. These are generated from code and reflect the current state of code in the Glance repository.
Sample configuration for Glance API¶
This sample configuration can also be viewed in glance-api.conf.sample.
[DEFAULT]
#
# From glance.api
#
# DEPRECATED:
# Set the image owner to tenant or the authenticated user.
#
# Assign a boolean value to determine the owner of an image. When set to
# True, the owner of the image is the tenant. When set to False, the
# owner of the image will be the authenticated user issuing the request.
# Setting it to False makes the image private to the associated user and
# sharing with other users within the same tenant (or "project")
# requires explicit image sharing via image membership.
#
# Possible values:
# * True
# * False
#
# Related options:
# * None
#
# (boolean value)
# This option is deprecated for removal since Rocky.
# Its value may be silently ignored in the future.
# Reason:
# The non-default setting for this option misaligns Glance with other
# OpenStack services with respect to resource ownership. Further, surveys
# indicate that this option is not used by operators. The option will be
# removed early in the 'S' development cycle following the standard OpenStack
# deprecation policy. As the option is not in wide use, no migration path is
# proposed.
#owner_is_tenant = true
# DEPRECATED:
# Role used to identify an authenticated user as administrator.
#
# Provide a string value representing a Keystone role to identify an
# administrative user. Users with this role will be granted
# administrative privileges.
#
# NOTE: The default value for this option has changed in this release.
#
# Possible values:
# * A string value which is a valid Keystone role
#
# Related options:
# * None
#
# (string value)
# This option is deprecated for removal since Ussuri.
# Its value may be silently ignored in the future.
# Reason:
# This option is redundant as its goal can be achieved via policy file
# configuration. Additionally, it can override any configured policies,
# leading to unexpected behavior and difficulty in policy configuration.
# The option will be removed early in the Victoria development cycle,
# following the standard OpenStack deprecation policy.
#
# Because this can be a security issue, the default value of this
# configuration option has been changed in this release.
#
# Please see the 'Deprecation Notes' section of the Ussuri Glance
# Release Notes for more information.

#
# Allow limited access to unauthenticated users.
#
# Assign a boolean to determine API access for unathenticated
# users. When set to False, the API cannot be accessed by
# unauthenticated users. When set to True, unauthenticated users can
# access the API with read-only privileges. This however only applies
# when using ContextMiddleware.

# (boolean value)
#allow_anonymous_access = false
#
# Limit the request ID length.
#
# Provide an integer value to limit the length of the request ID to

# Public url endpoint to use for Glance versions response.
#
# This is the public url endpoint that will appear in the Glance
# "versions" response. If no value is specified, the endpoint that is
# displayed in the version's response is that of the host running the
# API service. Change the endpoint to represent the proxy URL if the
# API service is running behind a proxy. If the service is running
# behind a load balancer, add the load balancer's URL for this value.

# DEPRECATED:
# 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
#
# (boolean value)
# This option is deprecated for removal since Ussuri.
# Its value may be silently ignored in the future.
# Reason:
# This option is redundant. Control custom image property usage via the
# 'image_property_quota' configuration option. This option is scheduled
# to be removed during the Victoria development cycle.

#
# Secure hashing algorithm used for computing the 'os_hash_value' property.
#
# This option configures the Glance "multihash", which consists of two
# image properties: the 'os_hash_algo' and the 'os_hash_value'. The
# 'os_hash_algo' will be populated by the value of this configuration
# option, and the 'os_hash_value' will be populated by the hexdigest computed
# when the algorithm is applied to the uploaded or imported image data.
#
# The value must be a valid secure hash algorithm name recognized by the
# python 'hashlib' library. You can determine what these are by examining
# the 'hashlib.algorithms_available' data member of the version of the
# library being used in your Glance installation. For interoperability
# purposes, however, we recommend that you use the set of secure hash
# names supplied by the 'hashlib.algorithms_guaranteed' data member because
# those algorithms are guaranteed to be supported by the 'hashlib' library
# on all platforms. Thus, any image consumer using 'hashlib' locally should
# be able to verify the 'os_hash_value' of the image.
#
# The default value of 'sha512' is a performant secure hash algorithm.
#
# If this option is misconfigured, any attempts to store image data will fail.
# For that reason, we recommend using the default value.

# 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

#
# 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

# 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

# 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

# This option is deprecated for removal since Newton.
# Its value may be silently ignored in the future.
# Reason: Use of this option, deprecated since Newton, is a security risk and
# will be removed once we figure out a way to satisfy those use cases that
# currently require it. An earlier announcement that the same functionality can
# be achieved with greater granularity by using policies is incorrect. You
# cannot work around this option via policy configuration at the present time,

# on the Glance release notes to stay up to date on progress in addressing this
# issue.

# Maximum size of image a user can upload in bytes.
#
# An image upload greater than the size mentioned here would result

#
# 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.

# Strategy to determine the preference order of image locations.
#
# This configuration option indicates the strategy to determine
# the order in which an image's locations must be accessed to
# serve the image's data. Glance then retrieves the image data
# from the first responsive active location it finds in this list.
#
# This option takes one of two possible values ``location_order``
# and ``store_type``. The default value is ``location_order``,
# which suggests that image data be served by using locations in
# the order they are stored in Glance. The ``store_type`` value
# sets the image location preference based on the order in which
# the storage backends are listed as a comma separated list for

# The location of the property protection file.
#
# Provide a valid path to the property protection file which contains

# with them.
#
# A property protection file, when set, restricts the Glance image
# properties to be created, read, updated and/or deleted by a specific
# set of users that are identified by either roles or policies.
# If this configuration option is not set, by default, property
# protections won't be enforced. If a value is specified and the file

# The driver to use for image cache management.
#
# This configuration option provides the flexibility to choose between the

# 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.

#
# 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.

# 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.

# Once an incomplete image spends more time than is specified here, it'll be

# 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.

# when the algorithm is applied to the uploaded or imported image data.
#
# The value must be a valid secure hash algorithm name recognized by the

# 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

# option, and the 'os_hash_value' will be populated by the hexdigest computed
# when the algorithm is applied to the uploaded or imported image data.
#
# The value must be a valid secure hash algorithm name recognized by the
# python 'hashlib' library. You can determine what these are by examining
# the 'hashlib.algorithms_available' data member of the version of the
# library being used in your Glance installation. For interoperability
# purposes, however, we recommend that you use the set of secure hash
# names supplied by the 'hashlib.algorithms_guaranteed' data member because
# those algorithms are guaranteed to be supported by the 'hashlib' library
# on all platforms. Thus, any image consumer using 'hashlib' locally should

# 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

# 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.
#

# nodes to keep the incomplete images from occupying disk space.

# 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.
