Error at running in a docker container

[DrMartiner]

I have simple code to watch ticker & order book:

from time import sleep
from datetime import datetime

from bittrex_websocket.websocket_client import BittrexSocket

class MySocket(BittrexSocket):
    def on_orderbook(self, msg):
        print(f'on_orderbook at {self.now}')

    def on_orderbook_update(self, msg):
        print(f'on_orderbook_update at {self.now}')

    def on_ticker_update(self, msg):
        print(f'on_ticker_update at {self.now}')

    @property
    def now(self):
        return datetime.now().strftime('%M:%S')

if __name__ == "__main__":
    ws = MySocket()
    ws.enable_log()

    ws.subscribe_to_orderbook(['USDT-ETH'], 30)
    ws.subscribe_to_ticker_update(['USDT-ETH'])

    while True:
        try:
            sleep(1)
        except KeyboardInterrupt:
            ws.disconnect()

I try to running it at docker (Python 3.6.0):

version: '2'
services:
  collector:
    build: './back/.'
    restart: 'always'
    command: 'python bittrex-collector.py'
    working_dir: '/app/'
    volumes:
      - './back:/app'

I have the errors when (docker-compose up):

Creating trusttrade_redis_1     ... done

Most likely nodejs is missing in your dockerfile.
