The following options can be set in the /etc/heat/heat.conf config file.
A sample configuration file is also available.
DEFAULT¶
- host¶
 - Type
 string
- Default
 <Hostname>
This option has a sample default set, which means that its actual default value may vary from the one documented above.
Name of the engine node. This can be an opaque identifier. It is not necessarily a hostname, FQDN, or IP address.
- plugin_dirs¶
 - Type
 list
- Default
 ['/usr/lib64/heat', '/usr/lib/heat', '/usr/local/lib/heat', '/usr/local/lib64/heat']

- Default
 /etc/heat/templates
The directory to search for template files.

 - Type
 string
- Default
 trusts- Valid Values
 password, trusts
Select deferred auth method, stored password or trusts.
Warning
This option is deprecated for removal since 9.0.0. Its value may be silently ignored in the future.

 False
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.

(Optional) If defined, indicate whether token data should be authenticated or authenticated and encrypted. If MAC, token data is authenticated (with HMAC) in the cache.

Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.
- service_token_roles¶
 - Type
 list
- Default
 ['service']
A choice of roles that must be present in a service token. 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.

- enforce_new_defaults¶
 - Type
 boolean
- Default
 False
This option controls whether or not to use old deprecated defaults when evaluating policies. If
True, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with theenforce_scopeflag so that you can get the benefits of new defaults andscope_typetogether.

Secret key(s) to use for encrypting context data for performance profiling.
This string value should have the following format: <key1>[,<key2>,…<keyn>], where each key is some random string. A user who triggers the profiling via the REST API has to set one of these keys in the headers of the REST API call to include profiling results of this node for this particular project.
Both “enabled” flag and “hmac_keys” config options should be set to enable profiling. Also, to generate correct profiling information across all services at least one key needs to be consistent between OpenStack projects. This ensures it can be used from client side to generate the trace, containing information from all possible resources.
