4.1.1. DEFAULT
The following table outlines the options available under the [DEFAULT]
group in the /etc/heat/heat.conf
file.
.
Configuration option = Default value | Type | Description |
---|---|---|
| integer value | Number of times to retry to bring a resource to a non-error state. Set to 0 to disable retries. |
| boolean value | Create trusts with redelegation enabled. This option is only used when reauthentication_auth_method is set to "trusts". Note that enabling this option does have security implications as all trusts created by Heat will use both impersonation and redelegation enabled. Enable it only when there are other services that need to create trusts from tokens Heat uses to access them, examples are Aodh and Heat in another region when configured to use trusts too. |
| string value | Key used to encrypt authentication info in the database. Length of this key must be 32 characters. |
| string value | Enable eventlet backdoor. Acceptable values are 0, <port>, and <start>:<end>, where 0 results in listening on a random tcp port number; <port> results in listening on the specified port number (and not enabling backdoor if that port is in use); and <start>:<end> results in listening on the smallest unused port number within the specified range of port numbers. The chosen port is displayed in the service’s log file. |
| string value | Enable eventlet backdoor, using the provided path as a unix socket that can receive connections. This option is mutually exclusive with backdoor_port in that only one should be provided. If both are provided then the existence of this option overrides the usage of that option.

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. |

| string value | 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. |
| string value | 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.

This option is deprecated in favor of www_authenticate_uri and will be removed in the S release. |

Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check. |
| boolean value | For backwards compatibility reasons we must let valid service tokens pass that don’t pass the service_token_roles check as valid. Setting this true will become the default in a future release and should be enabled if possible. |
| string value | The name or type of the service as it appears in the service catalog. This is used to validate tokens that have restricted access rules. |
| integer value | In order to prevent excessive effort spent validating tokens, the middleware caches previously-seen tokens for a configurable duration (in seconds). Set to -1 to disable caching completely. |
| string value | Complete "public" Identity API endpoint. This endpoint should not be an "admin" endpoint, as it should be accessible by all end users. Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies.
