Puppet Class: heat::engine

Defined in:
manifests/engine.pp

Overview

Class: heat::engine

Installs & configure the heat engine service

Parameters

auth_encryption_key

(required) Encryption key used for authentication info in database Must be either 16, 24, or 32 bytes long.

package_ensure

(Optional) Ensure state for package. Defaults to ‘present’

enabled

(optional) Should the service be enabled. Defaults to ‘true’

manage_service

(optional) Whether the service should be managed by Puppet. Defaults to true.

heat_stack_user_role

(optional) Keystone role for heat template-defined users. This setting does not actually create the role. If you change this to a different value you should also set heat::keystone::auth::heat_stack_user_role if you want the correct role created. Defaults to $::os_service_default.

heat_metadata_server_url

(optional) URL of the Heat metadata server Defaults to $::os_service_default.

heat_waitcondition_server_url

(optional) URL of the Heat waitcondition server Defaults to $::os_service_default.

engine_life_check_timeout

(optional) RPC timeout (in seconds) for the engine liveness check that is used for stack locking Defaults to $::os_service_default.

default_software_config_transport

(optional) Template default for how the server should receive the metadata required for software configuration. POLL_SERVER_CFN will allow calls to the cfn API action DescribeStackResource authenticated with the provided keypair (requires enabled heat-api-cfn). POLL_SERVER_HEAT will allow calls to the Heat API resource-show using the provided keystone credentials (requires keystone v3 API, and configured stack_user_* config options). POLL_TEMP_URL will create and populate a Swift TempURL with metadata for polling (requires object-store endpoint which supports TempURL). (string value) Allowed values: POLL_SERVER_CFN, POLL_SERVER_HEAT, POLL_TEMP_URL Defaults to $::os_service_default.

default_deployment_signal_transport

(optional) Template default for how the server should signal to heat with the deployment output values. CFN_SIGNAL will allow an HTTP POST to a CFN keypair signed URL (requires enabled heat-api-cfn). TEMP_URL_SIGNAL will create a Swift TempURL to be signaled via HTTP PUT (requires object-store TempURL). HEAT_SIGNAL will allow calls to the Heat API resource-signal using endpoint which supports the provided keystone credentials (string value) Allowed values: CFN_SIGNAL, TEMP_URL_SIGNAL, HEAT_SIGNAL Defaults to $::os_service_default.

default_user_data_format

(optional) Template default for how the user_data should be formatted for the server. For HEAT_CFNTOOLS, the user_data is bundled as part of the heat-cfntools cloud-init boot configuration data. For RAW the user_data is passed to Nova unmodified. For SOFTWARE_CONFIG user_data is bundled as part of the software config data, and metadata is derived from any associated SoftwareDeployment resources. Allowed values: HEAT_CFNTOOLS, RAW, SOFTWARE_CONFIG Defaults to $::os_service_default.

trusts_delegated_roles

(optional) Array of trustor roles to be delegated to heat. This value is also used by heat::keystone::auth if it is set to configure the keystone roles. Defaults to $::os_service_default.

instance_connection_is_secure

(Optional) Instance connection to CFN/CW API via https. Defaults to $::os_service_default

instance_connection_https_validate_certificates

(Optional) Instance connection to CFN/CW API validate certs if SSL is used. Defaults to $::os_service_default

max_resources_per_stack

(Optional) Maximum resources allowed per top-level stack. Defaults to $::os_service_default

num_engine_workers

(Optional) The number of workers to spawn. Defaults to $::os_workers_heat_engine

convergence_engine

(Optional) Enables engine with convergence architecture. Defaults to $::os_service_default.

reauthentication_auth_method

(Optional) Re-authentication method on token expiry. Defaults to $::os_service_default.

environment_dir

(Optional) The directory to search for environment files. Defaults to $::os_service_default

template_dir

(Optional) The directory to search for template files. Defaults to $::os_service_default

max_nested_stack_depth

(Optional) Maximum depth allowed when using nested stacks. Defaults to $::os_service_default

plugin_dirs

(Optional) List of directories to search for plug-ins. Defaults to $::os_service_default

client_retry_limit

(Optional) Number of times to retry when client encounters a transient error. Defaults to $::os_service_default

server_keystone_endpoint_type

(Optional) If set, is used to control which authentication endpoint is used by user-controlled servers to make calls back to Heat. Defaults to $::os_service_default
