Support for debugging node from Visual Studio code (etc)

[badrange]

As a developer I'd like to be able to debug the node project from vscode. I haven't been able to find information on how to configure mean to open up a port that vscode can connect to. A debug configuration similar to this should work - but what do I have to do to open up the port inside the container?

    {
      "type": "node",
      "request": "attach",
      "name": "Attach to node in Lando",
      "address": "192.168.16.6",      
      "port": 9229
    },
