The chosen port is displayed in the service’s log file.

glance¶
Configuration options for the Image service

Specifies the number of retries when uploading / downloading an image to / from glance. 0 means no retries.
- 
allowed_direct_url_schemes¶ - Type
 list
- Default
 ''
List of url schemes that can be directly accessed.
This option specifies a list of url schemes that can be downloaded directly via the direct_url. This direct_URL can be fetched from Image metadata which can be used by cyborg to get the image more efficiently. cyborg-compute could benefit from this by invoking a copy when it has access to the same file system as glance.
Possible values:
[file], Empty list (default)
Warning
This option is deprecated for removal since 17.0.0. Its value may be silently ignored in the future.
- Reason
 This was originally added for the ‘cyborg.image.download.file’ FileTransfer extension which was removed in the 16.0.0 Pike release. The ‘cyborg.image.download.modules’ extension point is not maintained and there is no indication of its use in production clouds.
- 
verify_glance_signatures¶ - Type
 boolean
- Default
 false
Enable image signature verification.
cyborg uses the image signature metadata from glance and verifies the signature of a signed image while downloading that image. If the image signature cannot be verified or if the image signature metadata is either incomplete or unavailable, then cyborg will not boot the image and instead will place the instance into an error state. This provides end users with stronger assurances of the integrity of the image data they are using to create servers.
Related options:
The options in the key_manager group, as the key_manager is used for the signature validation.
Both enable_certificate_validation and default_trusted_certificate_ids below depend on this option being enabled.
- 
enable_certificate_validation¶ - Type
 boolean
- Default
 false
Enable certificate validation for image signature verification.
During image signature verification cyborg will first verify the validity of the image’s signing certificate using the set of trusted certificates associated with the instance. If certificate validation fails, signature verification will not be performed and the instance will be placed into an error state. This provides end users with stronger assurances that the image data is unmodified and trustworthy. If left disabled, image signature verification can still occur but the end user will not have any assurance that the signing certificate used to generate the image signature is still trustworthy.
Related options:
This option only takes effect if verify_glance_signatures is enabled.
The value of default_trusted_certificate_ids may be used when this option is enabled.
Warning
This option is deprecated for removal since 16.0.0. Its value may be silently ignored in the future.
- Reason
 This option is intended to ease the transition for deployments leveraging image signature verification. The intended state long-term is for signature verification and certificate validation to always happen together.
- 
default_trusted_certificate_ids¶ - Type
 list
- Default
 ''
List of certificate IDs for certificates that should be trusted.
May be used as a default list of trusted certificate IDs for certificate validation. The value of this option will be ignored if the user provides a list of trusted certificate IDs with an instance API request. The value of this option will be persisted with the instance data if signature verification and certificate validation are enabled and if the user did not provide an alternative list. If left empty when certificate validation is enabled the user must provide a list of trusted certificate IDs otherwise certificate validation will fail.
Related options:
The value of this option may be used if both verify_glance_signatures and enable_certificate_validation are enabled.

In order to prevent excessive effort spent validating tokens, the middleware caches previously-seen tokens for a configurable duration (in seconds). Set to -1 to disable caching completely.
- 
memcache_security_strategy¶ - Type
 string
- Default
 None- Valid Values
 None, MAC, ENCRYPT
(Optional) If defined, indicate whether token data should be authenticated or authenticated and encrypted. If MAC, token data is authenticated (with HMAC) in the cache. If ENCRYPT, token data is encrypted and authenticated in the cache. If the value is not one of these options or empty, auth_token will raise an exception on initialization.

enforce_token_bind¶ - Type
 string
- Default
 permissive
Used to control the use and type of token binding. Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.
- 
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. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check.
- 
service_token_roles_required¶ - Type
 boolean
- Default
 false
For backwards compatibility reasons we must let valid service tokens pass that don’t pass the service_token_roles check as valid. Setting this true will become the default in a future release and should be enabled if possible.
