You want to make sure you don't lose any of your flow development. Make sure to map the host "flows" directory to the container directory as shown below. This will store the flow on your host machine if/when the container is destroyed.

module.exports = function (RED) {
    function FlightModeNode(config) {
        RED.nodes.createNode(this, config);
        var node = this;

        node.mode = config.mode || "Hold"; // Default to Hold if undefined

        node.on('input', function (msg) {
            // Ensure msg.payload carries the flight mode
            msg.payload = {
                "command": "set_mode",
                "mode": node.mode
            };
            node.send(msg);
        });
    }

    RED.nodes.registerType("flight-mode", FlightModeNode);
};
