Chapter 5. ironic


The following chapter contains information about the configuration options in the ironic service.

5.1. ironic.conf

This section contains options for the /etc/ironic/ironic.conf file.

The following table outlines the options available under the [DEFAULT] group in the /etc/ironic/ironic.conf file.

.

Configuration option = Default valueTypeDescription

auth_strategy = keystone

string value

This determines the granularity of rebalancing: given 10 hosts, and an exponent of the 2, there are 40 partitions in the ring.A few thousand partitions should make rebalancing smooth in most cases. The default is suitable for up to a few hundred conductors. Configuring for too many partitions has a negative impact on CPU usage.

Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies. If you’re using a versioned v2 endpoint here, then this should not be the same endpoint the service user utilizes for validating tokens, because normal end users may not be able to reach that endpoint. This option is deprecated in favor of www_authenticate_uri and will be removed in the S release. Deprecated since: Queens

*Reason:*The auth_uri option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

auth_version = None

string value

API version of the Identity API endpoint.

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.
