title: Execute windows python scripts via airflow docker container
body: <p>I'm working on windows, with Airflow set up via Docker. I've got a number of python scripts in windows that read and write from multiple locations in windows (SSH connections, windows folders etc). It'll be a lot of work to replicate all of these inputs inside my docker image, and so what I'm looking to do is get Airflow to execute these scripts as if they're running in windows.</p>
  
  <p>Is this possible, if so how?</p>
  
  <p>Here's the script that I'm running as my DAG:</p>
  
  <pre><code>from airflow import DAG
  from airflow.operators.bash_operator import BashOperator
  from airflow.operators.python_operator import PythonOperator
  from datetime import datetime, timedelta
  
  # Following are defaults which can be overridden later on
  default_args = {
      'owner': 'test',
      'depends_on_past': False,
      'start_date': datetime(2018, 11, 27),
      'email': ['test@gmail.com'],
      'email_on_failure': True,
      'email_on_retry': True,
      'retries': 1,
      'retry_delay': timedelta(minutes=1),
  }
  
  dag = DAG('Helloworld', default_args=default_args)
  
  ###########################################################
  # Here's where I want to execute my windows python script #
  ###########################################################
  t1=PythonOperator(dag=dag,
                 task_id='my_task_powered_by_python',
                 provide_context=False,
                 python_callable=r"C:\Users\user\Documents\script.py")
  
  t2 = BashOperator(
      task_id='task_2',
      bash_command='echo "Hello World from Task 2"',
      dag=dag)
  
  t3 = BashOperator(
      task_id='task_3',
      bash_command='echo "Hello World from Task 3"',
      dag=dag)
  
  t4 = BashOperator(
      task_id='task_4',
      bash_command='echo "Hello World from Task 4"',
      dag=dag)
  
  t2.set_upstream(t1)
  t3.set_upstream(t1)
  t4.set_upstream(t2)
  t4.set_upstream(t3)
