| Configuration option = Default value | Description |
|---|---|
| [DEFAULT] | |
client_retry_limit = 2 |
(Integer) Number of times to retry when a client encounters an expected intermittent error. Set to 0 to disable retries. |
convergence_engine = True |
(Boolean) Enables engine with convergence architecture. All stacks with this option will be created using convergence engine. |
default_deployment_signal_transport =
CFN_SIGNAL |
(String) 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 endpoint which supports TempURL). HEAT_SIGNAL will allow calls to the Heat API resource-signal using the provided keystone credentials. ZAQAR_SIGNAL will create a dedicated zaqar queue to be signaled using the provided keystone credentials. |
default_software_config_transport =
POLL_SERVER_CFN |
(String) 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).ZAQAR_MESSAGE will create a dedicated zaqar queue and post the metadata for polling. |
deferred_auth_method = trusts |
(String) Select deferred auth method, stored password or trusts. |
environment_dir =
/etc/heat/environment.d |
(String) The directory to search for environment files. |
error_wait_time = 240 |
(Integer) The amount of time in seconds after an error has occurred that tasks may continue to run before being cancelled. |
event_purge_batch_size = 10 |
(Integer) Controls how many events will be pruned whenever a stack's events exceed max_events_per_stack. Set this lower to keep more events at the expense of more frequent purges. |
executor_thread_pool_size = 64 |
(Integer) Size of executor thread pool. |
host = localhost |
(String) Name of the engine node. This can be an opaque identifier. It is not necessarily a hostname, FQDN, or IP address. |
keystone_backend =
heat.engine.clients.os.keystone.heat_keystoneclient.KsClientWrapper |
(String) Fully qualified class name to use as a keystone backend. |
max_interface_check_attempts = 10 |
(Integer) Number of times to check whether an interface has been attached or detached. |
periodic_interval = 60 |
(Integer) Seconds between running periodic tasks. |
plugin_dirs =
/usr/lib64/heat, /usr/lib/heat, /usr/local/lib/heat, /usr/local/lib64/heat |
(List) List of directories to search for plug-ins. |
reauthentication_auth_method = |
(String) Allow reauthentication on token expiry, such that long-running tasks may complete. Note this defeats the expiry of any provided user tokens. |
template_dir = /etc/heat/templates |
(String) The directory to search for template files. |
| [constraint_validation_cache] | |
caching = True |
(Boolean) Toggle to enable/disable caching when Orchestration Engine validates property constraints of stack.During property validation with constraints Orchestration Engine caches requests to other OpenStack services. Please note that the global toggle for oslo.cache(enabled=True in [cache] group) must be enabled to use this feature. |
expiration_time = 60 |
(Integer) TTL, in seconds, for any cached item in the dogpile.cache region used for caching of validation constraints. |
| [resource_finder_cache] | |
caching = True |
(Boolean) Toggle to enable/disable caching when Orchestration Engine looks for other OpenStack service resources using name or id. Please note that the global toggle for oslo.cache(enabled=True in [cache] group) must be enabled to use this feature. |
expiration_time = 3600 |
(Integer) TTL, in seconds, for any cached item in the dogpile.cache region used for caching of OpenStack service finder functions. |
| [revision] | |
heat_revision = unknown |
(String) Heat build revision. If you would prefer to manage your build revision separately, you can move this section to a different file and add it as another config option. |
| [service_extension_cache] | |
caching = True |
(Boolean) Toggle to enable/disable caching when Orchestration Engine retrieves extensions from other OpenStack services. Please note that the global toggle for oslo.cache(enabled=True in [cache] group) must be enabled to use this feature. |
expiration_time = 3600 |
(Integer) TTL, in seconds, for any cached item in the dogpile.cache region used for caching of service extensions. |
| [volumes] | |
backups_enabled = True |
(Boolean) Indicate if cinder-backup service is enabled. This is a temporary workaround until cinder-backup service becomes discoverable, see LP#1334856. |
| [yaql] | |
limit_iterators = 200 |
(Integer) The maximum number of elements in collection expression can take for its evaluation. |
memory_quota = 10000 |
(Integer) The maximum size of memory in bytes that expression can take for its evaluation. |
