DEFAULT

owner_is_tenant
Type:boolean
Default:true

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. Services which consume this: * glance-api * glare-api * glance-registry Possible values: * True * False Related options: * None

Default:admin

Role used to identify an authenticated user as administrator. Provide a string value representing a Keystone role to identify an administrative user.

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.

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.

Finally the name of a binding method that must be present in tokens.

Default:false

If true, the revocation list will be checked for cached tokens. This requires that PKI tokens are configured on the identity server.

The hashes will be tried in the order given, so put the preferred one first for performance. The result of the first hash will be stored in the cache. This will typically be set to multiple values only while migrating from a less secure algorithm to a more secure one. Once all the old tokens are expired this option should be set to a single value for better performance.

hmac_keys
Type:string
Default:SECRET_KEY

Secret key(s) to use for encrypting context data for performance profiling. This string value should have the following format: <key1>[,<key2>,...<keyn>], where each key is some random string. A user who triggers the profiling via the REST API has to set one of these keys in the headers of the REST API call to include profiling results of this node for this particular project. Both “enabled” flag and “hmac_keys” config options should be set to enable profiling. Also, to generate correct profiling information across all services at least one key needs to be consistent between OpenStack projects. This ensures it can be used from client side to generate the trace, containing information from all possible resources.
