The Ironic REST API expects a new X-OpenStack-Ironic-API-Version header be passed with each HTTP[S] request. This header allows client and server to negotiate a mutually supported interface.[1] In the absence of this header, the REST service will default to a compatibility mode and yield responses compatible with Juno clients. This mode, however, prevents access to most features introduced in Kilo.
