Configuration options for the Orchestration service¶

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']

The directory to search for environment files.

template_dir¶

Type: string
Default: /etc/heat/templates

The directory to search for template files.

deferred_auth_method¶

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.

Reason: Stored password based deferred auth is broken when used with keystone v3 and is not supported.

reauthentication_auth_method¶

Type: string
Default: ''
Valid Values: ‘’, trusts

Allow reauthentication on token expiry, such that long-running tasks may complete. Note this defeats the expiry of any provided user tokens.

allow_trusts_redelegation¶

Type: boolean
Default: 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. 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.

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. 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.

service_token_roles_required¶

Type: boolean
Default: False

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.

enforce_new_defaults¶

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 the enforce_scope flag so that you can get the benefits of new defaults and scope_type together

policy_file¶

Type: string

Default: SECRET_KEY

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.
