The Bare Metal service is configured via its configuration file. This file is typically located at ``/etc/ironic/ironic.conf``. Although some configuration options are mentioned here, it is recommended that you review all the :doc:`/configuration/sample-config` so that the Bare Metal service is configured for your needs. It is possible to set up an ironic-api and an ironic-conductor services on the same host or different hosts. Users also can add new ironic-conductor hosts to deal with an increasing number of bare metal nodes. But the additional ironic-conductor services should be at the same version as that of existing ironic-conductor services.
