1. The controller does not accept any dynamic user config through flags. All user interaction is through the
IstioOperator CR.
1. The controller has additional logic that mirrors istioctl commands like upgrade, but is driven from the declarative
API rather than command line.

### Quick tour of CLI commands

#### Flags

The `istioctl` command supports the following flags:

			args:              strings.Split("group create --name foo", " "),
			expectedException: true,
			expectedOutput:    "Error: expecting a workload namespace\n",
		},
		{
			description:       "valid case - minimal flags, infer defaults",
			args:              strings.Split("group create --name foo --namespace bar", " "),
			expectedException: false,
			expectedOutput:    defaultYAML,
		},
		{

			return validateFiles(&istioNamespace, defaultNamespace, filenames, c.OutOrStderr())
		},
	}

	flags := c.PersistentFlags()
	flags.StringSliceVarP(&filenames, "filename", "f", nil, "Inputs of files to validate")
	flags.BoolVarP(&referential, "referential", "x", true, "Enable structural validation for policy and telemetry")
	_ = flags.MarkHidden("referential")
	return c
}
