get_catalog(user_id, project_id)

Retrieve and format the V2 service catalog.

Parameters:

• user_id – The id of the user who has been authenticated for creating service catalog.
• project_id – The id of the project. ‘project_id’ will be None in the case this being called to create a catalog to go in a domain scoped token. In this case, any endpoint that requires a project_id as part of their URL will be skipped (as would a whole service if, as a consequence, it has no valid endpoints).

Returns:

A nested dict representing the service catalog or an empty dict.

keystone.catalog.backends.templated module

class keystone.catalog.backends.templated.Catalog(templates=None)

Bases: keystone.catalog.backends.base.CatalogDriverBase

A backend that generates endpoints for the Catalog based on templates.

It is usually configured via config entries that look like:

catalog.$REGION.$SERVICE.$key = $value

and is stored in a similar looking hierarchy. Where a value can contain values to be interpolated by standard python string interpolation that look like (the % is replaced by a $ due to paste attempting to interpolate on its own:

http://localhost:$(public_port)s/

When expanding the template it will pass in a dict made up of the conf instance plus a few additional key-values, notably project_id and user_id.

It does not care what the keys and values are but it is worth noting that keystone_compat will expect certain keys to be there so that it can munge them into the output format keystone expects. These keys are:

name - the name of the service, most likely repeated for all services of

the same type, across regions.

adminURL - the url of the admin endpoint

publicURL - the url of the public endpoint

internalURL - the url of the internal endpoint
