Noobs question on deploying and build app

Hello, i’ve successfully deploy my app on an ubuntu server using kadirah/mup. Now im a bit confused on how to make my apk and link it with my server. I guess i need to use :

meteor build myandroidapkname --server ipofmyserver:port

So here is where i wonder how to be sure of the port use by mup and should i make this meteor build command on my server or i can do it with my local files ?

I’ve tried reading meteor doc about that but there are not too much examples, so i thank u in advance for any inforamtions or link to tutorials or video.

Here is mup.js file is there a place i can add the port ?

module.exports = {
  servers: {
    one: {
      host: '',
      username: 'myusername',
      password: 'mypassword
      // pem:
      // password:
      // or leave blank for authenticate from ssh-agent

  meteor: {
    name: '',
    path: '../',
    servers: {
      one: {}
    buildOptions: {
      serverOnly: true,
    env: {
      ROOT_URL: '',
      MONGO_URL: 'mongodb://localhost/meteor'

    dockerImage: 'abernix/meteord:base',
    deployCheckWaitTime: 60

  mongo: {
    oplog: true,
    port: 27017,
    servers: {
      one: {},
