Meteor Up mup deploy fails - Error response from daemon

Question

I have a Meteor application that I'm trying to deploy on a VPS. I am using Meteor Up to do this.

By following the instructions I have set up my mup.js file to look like this:

module.exports = {
  servers: {
    one: {
      host: '41.185.27.69',
      username: 'root',
      // pem:
      password: 'secret',
      // or leave blank for authenticate from ssh-agent
      opts: {
        port: 22
      }
    }
  },

  meteor: {
    name: 'HelderbergLink',
    path: '../../HelderbergLink',
    servers: {
      one: {}
    },
    buildOptions: {
      serverOnly: true,
    },
    env: {
      ROOT_URL: 'http://41.185.27.69',
      MONGO_URL: 'mongodb://127.0.0.1:27017/HelderbergLink'
    },

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

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

After this is set up I run the following command in my .deploy directory:

mup.cmd setup

Everything setups successfully here, but then when I need to run the next command:

mup.cmd deploy

It runs through most of the process but then gives me this error:

I'm not sure what to do to resolve this. Any help would be much appreciated!
