client_package_ensure

(Optional) Desired ensure state of the client package. accepts latest or specific versions. Defaults to present.

catalog_driver

(Optional) Catalog driver used by Keystone to store endpoints and services. Defaults to false.

catalog_template_file

(Optional) Path to the catalog used if ‘templated’ catalog driver is used. Defaults to ‘/etc/keystone/default_catalog.templates’

token_provider

(Optional) Format keystone uses for tokens. Defaults to ‘fernet’ Supports fernet or uuid.

revoke_driver

(Optional) Driver for token revocation. Defaults to $::os_service_default

revoke_by_id

(Optional) Revoke token by token identifier. Setting revoke_by_id to true enables various forms of enumerating tokens. These enumerations are processed to determine the list of tokens to revoke. Only disable if you are switching to using the Revoke extension with a backend other than KVS, which stores events in memory. Defaults to true.

manage_service

(Optional) If Puppet should manage service startup / shutdown. Defaults to true.

enabled

(Optional) If the keystone services should be enabled. Default to true.

(Optional) A URL representing the messaging driver to use and its full configuration. Transport URLs take the form:

transport://user:pass@host1:port[,hostN:portN]/virtual_host

Defaults to $::os_service_default

rabbit_ha_queues

(Optional) Use HA queues in RabbitMQ. Defaults to $::os_service_default

rabbit_heartbeat_timeout_threshold

(Optional) Number of seconds after which the RabbitMQ broker is considered down if the heartbeat keepalive fails. Any value >0 enables heartbeats. Heartbeating helps to ensure the TCP connection to RabbitMQ isn’t silently closed, resulting in missed or lost messages from the queue. (Requires kombu >= 3.0.7 and amqp >= 1.4.0) Defaults to $::os_service_default

rabbit_heartbeat_rate

(Optional) How often during the rabbit_heartbeat_timeout_threshold period to check the heartbeat on RabbitMQ connection. (i.e. rabbit_heartbeat_rate=2 when rabbit_heartbeat_timeout_threshold=60, the heartbeat will be checked every 30 seconds. Defaults to $::os_service_default

rabbit_heartbeat_in_pthread

(Optional) EXPERIMENTAL: Run the health check heartbeat thread through a native python thread. By default if this option isn’t provided the health check heartbeat will inherit the execution model from the parent process. By example if the parent process have monkey patched the stdlib by using eventlet/greenlet then the heartbeat will be run through a green thread. Defaults to $::os_service_default

kombu_compression

(Optional) Possible values are: gzip, bz2. If not set compression will not be used. This option may notbe available in future versions. EXPERIMENTAL. (string value) Defaults to $::os_service_default

notification_transport_url

(Optional) A URL representing the messaging driver to use for notifications and its full configuration. Transport URLs take the form:

transport://user:pass@host1:port[,hostN:portN]/virtual_host

Defaults to $::os_service_default

notification_driver

RPC driver. Not enabled by default (list value) Defaults to $::os_service_default

notification_topics

(Optional) AMQP topics to publish to when using the RPC notification driver. (list value) Default to $::os_service_default

notification_format

(Optional) Define the notification format for identity service events. Valid values are ‘basic’ and ‘cadf’. Default to $::os_service_default

rpc_response_timeout

(Optional) Seconds to wait for a response from a call. Defaults to $::os_service_default

public_endpoint

(Optional) The base public endpoint URL for keystone that are advertised to clients (NOTE: this does NOT affect how keystone listens for connections) (string value) Defaults to $::os_service_default

service_name

(Optional) Name of the service that will be providing the server functionality of keystone. For example, the default is just ‘keystone’, which means keystone will be run as a standalone service, and will able to be managed separately by the operating system’s service manager. For example, under Red Hat based systems, you will be able to use: systemctl restart openstack-keystone to restart the service. Under Debian, which uses uwsgi (as opposed to eventlet), the service name is simply keystone, so this will work: systemctl restart keystone If the value is ‘httpd’, this means keystone will be a web service, and you must use another class to configure that web service. After calling class ‘keystone’… use class { ‘keystone::wsgi::apache’…} to make keystone be a web app using apache mod_wsgi. Defaults to ‘$::keystone::params::service_name’

max_token_size

(Optional) maximum allowable Keystone token size Defaults to $::os_service_default

sync_db

(Optional) Run db sync on the node. Defaults to true

enable_fernet_setup

(Optional) Setup keystone for fernet tokens. This is typically only run on a single node, then the keys are replicated to the other nodes in a cluster. You would typically also pair this with a fernet token provider setting. Defaults to true

fernet_key_repository

(Optional) Location for the fernet key repository. This value must be set if enable_fernet_setup is set to true. Defaults to ‘/etc/keystone/fernet-keys’

fernet_max_active_keys

(Optional) Number of maximum active Fernet keys. Integer > 0. Defaults to $::os_service_default

fernet_keys

(Optional) Hash of Keystone fernet keys If you enable this parameter, make sure enable_fernet_setup is set to True. Example of valid value: fernet_keys:

/etc/keystone/fernet-keys/0:
  content: c_aJfy6At9y-toNS9SF1NQMTSkSzQ-OBYeYulTqKsWU=
/etc/keystone/fernet-keys/1:
  content: zx0hNG7CStxFz5KXZRsf7sE4lju0dLYvXdGDIKGcd7k=

Puppet will create a file per key in $fernet_key_repository. Note: defaults to false so keystone-manage fernet_setup will be executed. Otherwise Puppet will manage keys with File resource. Defaults to false

fernet_replace_keys

(Optional) Whether or not to replace the fernet keys if they are already in the filesystem Defaults to true

enable_credential_setup

(Optional) Setup keystone for credentials. In a cluster environment where multiple Keystone nodes are running, you might need the same keys everywhere; so you’ll have to set credential_keys parameter in order to let Puppet manage Keystone keys in a consistent way, otherwise keystone-manage will generate different set of keys on keystone nodes and the service won’t work. Defaults to False

credential_key_repository

(Optional) Location for the Credential key repository. This value must be set if enable_credential_setup is set to true. Defaults to ‘/etc/keystone/credential-keys’

credential_keys

(Optional) Hash of Keystone credential keys If you enable this parameter, make sure enable_credential_setup is set to True. Example of valid value: credential_keys:

/etc/keystone/credential-keys/0:
  content: t-WdduhORSqoyAykuqWAQSYjg2rSRuJYySgI2xh48CI=
/etc/keystone/credential-keys/1:
  content: GLlnyygEVJP4-H2OMwClXn3sdSQUZsM5F194139Unv8=

Puppet will create a file per key in $credential_key_repository. Note: defaults to false so keystone-manage credential_setup will be executed. Otherwise Puppet will manage keys with File resource. Defaults to false

default_domain

(Optional) When Keystone v3 support is enabled, v2 clients will need to have a domain assigned for certain operations. For example, doing a user create operation must have a domain associated with it. This is the domain which will be used if a domain is needed and not explicitly set in the request. Using this means that you will have to add it to every user/tenant/user_role you create, as without a domain qualification those resources goes into “Default” domain. See README. Defaults to undef (will use built-in Keystone default)

policy_driver

Policy backend driver. (string value) Defaults to $::os_service_default.

using_domain_config

(Optional) Eases the use of the keystone_domain_config resource type. It ensures that a directory for holding the domain configuration is present and the associated configuration in keystone.conf is set up right. Defaults to false

domain_config_directory

(Optional) Specify a domain configuration directory. For this to work the using_domain_config must be set to true. Raise an error if it’s not the case. Defaults to ‘/etc/keystone/domains’
