To create an install disk invoke the create-ignition-disk command. The tool will then prompt the user to input the required parameters. Alternatively, the parameters can be passed as command line arguments. The following example creates an install disk on /dev/sdb managed by the computer at 192.168.1.1

    node_deployer create-ignition-disk -d /dev/sdb -ip 192.168.1.1

The user will then be prompted to input a password and swarm token.
