Hapi Pack through code or through Composer

config.json

{
    "servers": [
        {
            "port"  : 8000,
            "labels": ["public"]
        }
    ],
    "plugins": {
        "capi-web": { }
    }
}

index.js

var Hapi = require('hapi');

var pack = new Hapi.Pack();
pack.server(8000, { labels: ['public'] });

pack.require('capi-web', {}, function(err) {

});
pack.start(function () {
    console.log('All servers started');
});

The labels need to be in options, like:

"servers": [
{
  "port": 8000,
  "options": {
    "labels": ['public']
  }
}
