+<3> For each node in your cluster, specify the hostname path to your node and the base-64 encoded Ignition configuration file data for the machine type. The `worker` role is the default role for nodes in your cluster. The `.yaml` extension does not work when specifying the short hostname, `hostname -s`, path for each node or all nodes in the `MachineConfig` manifest file.

+Alternatively, if you have a single global configuration specified in an `/etc/nmstate/openshift/cluster.yml` configuration file that you want to apply to all nodes in your cluster, you do not need to specify the hostname path for each node, such as `/etc/nmstate/openshift/<node_hostname>.yml`.
