[Help] How to specify node version

[s7dhansh]

When using this image with mup, I am trying to specify node version 4.6.2, using

docker: {
            image: 'abernix/meteord:base', //optional
            args: ['-v /etc/timezone:/etc/timezone', '-v /etc/localtime:/etc/localtime', '--build-arg NODE_VERSION=4.6.2']
        },

It fails with the error : unknown flag: --build-arg

What is the proper procedure?

EDIT: Why 4.6.2? Because Node 4.7+ is causing distinct memory and cpu overuse.

On reading further I assume that I have to build a new image entirely from this repo using build-arg? Is there any simpler way?

The Node version is baked in, however you can use whichever previous tag you'd like from this list of tags. Remember to consider Node Security issues when using an older version though.
