 The following options can be passed via the `-o` flag of the `create` command:
 
-* `image_name`: Name of the image to use to spawn VMs
-* `keypair` (default to `${LOGNAME}_key`): Name of the ssh key
-* `public_key` (default to `~/.ssh/id_rsa.pub`): filename of the ssh public key
-* `master_flavor` (default to `m1.small`): The ID or name of the flavor for the master
-* `node_flavor` (default to `m1.medium`): The ID or name of the flavor for the nodes
 * `infra_heat_stack` (default to `playbooks/openstack/openshift-cluster/files/heat_stack.yaml`): filename of the HEAT template to use to create the cluster infrastructure
 
 The following options are used only by `heat_stack.yaml`. They are so used only if the `infra_heat_stack` option is left with its default value.
