keystone.resource.core module

Main entry point into the Resource service.

class keystone.resource.core.DomainConfigManager

Bases: keystone.common.manager.Manager

Default pivot point for the Domain Config backend.

create_config(domain_id, config)

Create config for a domain.

Parameters

• domain_id – the domain in question

• config – the dict of config groups/options to assign to the domain

Creates a new config, overwriting any previous config (no Conflict error will be generated).

Returns

a dict of group dicts containing the options, with any that are sensitive removed

Raises

keystone.exception.InvalidDomainConfig – when the config contains options we do not support

delete_config(domain_id, group=None, option=None)

Delete config, or partial config, for the domain.

Parameters

• domain_id – the domain in question

• group – an optional specific group of options

• option – an optional specific option within the group

If group and option are None, then the entire config for the domain is deleted. If group is not None, then just that group of options will be deleted. If group and option are both specified, then just that option is deleted.

Raises

keystone.exception.InvalidDomainConfig – when group/option parameters specify an option we do not support or one that does not exist in the original config.

driver_namespace = 'keystone.resource.domain_config'

get_config(domain_id, group=None, option=None)

Get config, or partial config, for a domain.

Parameters

• domain_id – the domain in question

• group – an optional specific group of options

• option – an optional specific option within the group

Returns

a dict of group dicts containing the whitelisted options, filtered by group and option specified

Raises

• keystone.exception.DomainConfigNotFound – when no config found that matches domain_id, group and option specified

• keystone.exception.InvalidDomainConfig – when the config and group/option parameters specify an option we do not support

An example response:

}

get_config_default(group=None, option=None)

Get default config, or partial default config.

Parameters

• group – an optional specific group of options

• option – an optional specific option within the group

Returns

a dict of group dicts containing the default options, filtered by group and option if specified

Raises

keystone.exception.InvalidDomainConfig – when the config and group/option parameters specify an option we do not support (or one that is not whitelisted).

An example response:

get_config_with_sensitive_info(domain_id)

Get config for a domain with sensitive info included.

This method is not exposed via the public API, but is used by the identity manager to initialize a domain with the fully formed config options.

get_security_compliance_config(domain_id, group, option=None)

Get full or partial security compliance config from configuration.

Parameters

• domain_id – the domain in question

• group – a specific group of options

• option – an optional specific option within the group

Returns

a dict of group dicts containing the whitelisted options, filtered by group and option specified

Raises

keystone.exception.InvalidDomainConfig – when the config and group/option parameters specify an option we do not support

An example response:

{
    'security_compliance': {
        'password_regex': '^(?=.*\d)(?=.*[a-zA-Z]).{7,}$'

            'A password must consist of at least 1 letter, '
            '1 digit, and have a minimum length of 7 characters'
        }
}

sensitive_options = {'identity': [], 'ldap': ['password']}

update_config(domain_id, config, group=None, option=None)

Update config, or partial config, for a domain.

Parameters

• domain_id – the domain in question

• config – the config dict containing and groups/options being updated

• group – an optional specific group of options, which if specified must appear in config, with no other groups

• option – an optional specific option within the group, which if specified must appear in config, with no other options

The contents of the supplied config will be merged with the existing config for this domain, updating or creating new options if these did not previously exist. If group or option is specified, then the update will be limited to those specified items and the inclusion of other options in the supplied config will raise an exception, as will the situation when those options do not already exist in the current config.

Returns

a dict of groups containing all whitelisted options

Raises

keystone.exception.InvalidDomainConfig – when the config and group/option parameters specify an option we do not support or one that does not exist in the original config

class keystone.resource.core.Manager

Bases: keystone.common.manager.Manager

Default pivot point for the Resource backend.

See keystone.common.manager.Manager for more details on how this dynamically calls the backend.

assert_domain_enabled(domain_id, domain=None)

Assert the Domain is enabled.

Raises

AssertionError – if domain is disabled.

assert_domain_not_federated(domain_id, domain)

Assert the Domain’s name and id do not match the reserved keyword.

Note that the reserved keyword is defined in the configuration file, by default, it is ‘Federated’, it is also case insensitive. If config’s option is empty the default hardcoded value ‘Federated’ will be used.

Raises

AssertionError – if domain named match the value in the config.

assert_project_enabled(project_id, project=None)

Assert the project is enabled and its associated domain is enabled.

Raises

AssertionError – if the project or domain is disabled.

get_project(project_id)

get_project_by_name(project_name, domain_id)

get_project_parents_as_ids(project)

Get the IDs from the parents from a given project.

The project IDs are returned as a structured dictionary traversing up the hierarchy to the top level project. For example, considering the following project hierarchy:

  A
  |
+-B-+
|   |
C   D

If we query for project C parents, the expected return is the following dictionary:

'parents': {
    B['id']: {
        A['id']: None
    }
}

get_project_tag(project_id, tag_name)

Return information for a single tag on a project.

Parameters

Raises

keystone.exception.ProjectTagNotFound – If the tag name does not exist on the project

Returns

The tag value

get_projects_in_subtree_as_ids(project_id)

Get the IDs from the projects in the subtree from a given project.

The project IDs are returned as a structured dictionary representing their hierarchy. For example, considering the following project hierarchy:

  A
  |
+-B-+
|   |
C   D

If we query for project A subtree, the expected return is the following dictionary:

'subtree': {
    B['id']: {
        C['id']: None,
        D['id']: None
    }
}
