glance-registry.conf

This configuration file controls how the register server operates. More information can be found in Configuring the Glance Registry.

DEFAULT

owner_is_tenant

Type:boolean Default:true

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

admin_role

Type:string Default:admin

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. The default value for this option is ‘admin’. Possible values: * A string value which is a valid Keystone role Related options: * None

allow_anonymous_access

Type:boolean Default:false

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. Possible values: * True * False Related options: * None

max_request_id_length

Type:integer Default:64 Minimum Value:0

Limit the request ID length. Provide an integer value to limit the length of the request ID to the specified length. The default value is 64. Users can change this to any ineteger value between 0 and 16384 however keeping in mind that a larger value may flood the logs. Possible values: * Integer value between 0 and 16384 Related options: * None

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 Ocata release 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:string Default:localhost

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

bind_host

Type:string Default:0.0.0.0

IP address to bind the glance servers to. Provide an IP address to bind the glance server to. The default value is 0.0.0.0. Edit this option to enable the server to listen on one particular IP address on the network card. This facilitates selection of a particular network interface for the server. Possible values: * A valid IPv4 address * A valid IPv6 address Related options: * None

bind_port

Type:unknown type Default:<None> Minimum Value:0 Maximum Value:65535

Port number on which the server will listen. Provide a valid port number to bind the server’s socket to. This port is then set to identify processes and forward network messages that arrive at the server. The default bind_port value for the API server is 9292 and for the registry server is 9191. Possible values: * A valid port number (0 to 65535) Related options: * None

backlog

Type:integer Default:4096 Minimum Value:1

Set the number of incoming connection requests. Provide a positive integer value to limit the number of requests in the backlog queue. The default queue size is 4096. An incoming connection to a TCP listener socket is queued before a connection can be established with the server. Setting the backlog for a TCP socket ensures a limited queue size for incoming traffic. Possible values: * Positive integer Related options: * None

tcp_keepidle

Type:integer Default:600 Minimum Value:1

Set the wait time before a connection recheck. Provide a positive integer value representing time in seconds which is set as the idle wait time before a TCP keep alive packet can be sent to the host. The default value is 600 seconds. Setting tcp_keepidle helps verify at regular intervals that a connection is intact and prevents frequent TCP connection reestablishment. Possible values: * Positive integer value representing time in seconds Related options: * None

ca_file

Type:string Default:/etc/ssl/cafile

Absolute path to the CA file. Provide a string value representing a valid absolute path to the Certificate Authority file to use for client authentication. A CA file typically contains necessary trusted certificates to use for the client authentication. This is essential to ensure that a secure connection is established to the server via the internet. Possible values: * Valid absolute path to the CA file Related options: * None

cert_file

Type:string Default:/etc/ssl/certs

Absolute path to the certificate file. Provide a string value representing a valid absolute path to the certificate file which is required to start the API service securely. A certificate file typically is a public key container and includes the server’s public key, server name, server information and the signature which was a result of the verification process using the CA certificate. This is required for a secure connection establishment. Possible values: * Valid absolute path to the certificate file Related options: * None

key_file

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

Absolute path to a private key file. Provide a string value representing a valid absolute path to a private key file which is required to establish the client-server connection. Possible values: * Absolute path to the private key file Related options: * None

Warning

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

Reason:Use the http_proxy_to_wsgi middleware instead.

workers

Type:integer Default:<None> Minimum Value:0

Number of Glance worker processes to start. Provide a non-negative integer value to set the number of child process workers to service requests. By default, the number of CPUs available is set as the value for workers. Each worker process is made to listen on the port set in the configuration file and contains a greenthread pool of size 1000. NOTE: Setting the number of workers to zero, triggers the creation of a single API process with a greenthread pool of size 1000. Possible values: * 0 * Positive integer value (typically equal to the number of CPUs) Related options: * None

max_header_line

Type:integer Default:16384 Minimum Value:0

Maximum line size of message headers. Provide an integer value representing a length to limit the size of message headers. The default value is 16384. NOTE: max_header_line may need to be increased when using large tokens (typically those generated by the Keystone v3 API with big service catalogs). However, it is to be kept in mind that larger values for max_header_line would flood the logs. Setting max_header_line to 0 sets no limit for the line size of message headers. Possible values: * 0 * Positive integer Related options: * None

http_keepalive

Type:boolean Default:true

Set keep alive option for HTTP over TCP. Provide a boolean value to determine sending of keep alive packets. If set to False, the server returns the header “Connection: close”. If set to True, the server returns a “Connection: Keep-Alive” in its responses. This enables retention of the same TCP connection for HTTP conversations instead of opening a new one with each new request. This option must be set to False if the client socket connection needs to be closed explicitly after the response is received and read successfully by the client. Possible values: * True * False Related options: * None

client_socket_timeout

Type:integer Default:900 Minimum Value:0

Timeout for client connections’ socket operations. Provide a valid integer value representing time in seconds to set the period of wait before an incoming connection can be closed. The default value is 900 seconds. The value zero implies wait forever. Possible values: * Zero * Positive integer Related options: * None

keystone_authtoken

auth_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.

auth_version

Type:string Default:<None>
