shachibista opened a new issue #10388:
URL: https://github.com/apache/airflow/issues/10388


   **Description**
   
   Currently, the airflow project uses PEP-3143 style daemons to launch tasks 
(as implemented in https://pypi.org/project/python-daemon/), however this is 
targeted towards unix daemons. As a result, running airflow on windows requires 
multiple levels of abstraction each with their own problems. Would it be 
possible to use something like daemoniker 
(https://daemoniker.readthedocs.io/en/latest/) to launch tasks? What are the 
challenges and issues?
   
   In machine learning workflows, with large datasets, it is a huge time-saver 
if the pipeline tasks can be run on the GPU. WSL 1 does not support GPU 
passthrough, docker through WSL 2 supports GPU passthrough only with the 
Insiders build, additionally it has issues with networking when connected to 
VPN (https://github.com/microsoft/WSL/issues/5068). 
   
   **Use case / motivation**
   
   Natively running airflow without WSL 1/2 or docker on Windows. This is 
helpful in cases where the company ecosystem is windows-based. 
   
   **Possible implementation**
   
   The daemon module is only used to daemonize the scheduler and webserver. 
Here's a sample code that runs the scheduler (airflow origin/v1-10-stable) 
using daemoniker, comments are welcome:
   
   ```python
   # airflow/bin/cli.py
   from daemoniker import Daemonizer
   
   ...
   
   if args.daemon:
       with Daemonizer() as (is_setup, daemonizer):
           if is_setup:
               pid, stdout, stderr, log_file = setup_locations("scheduler",
                                                       args.pid,
                                                       args.stdout,
                                                       args.stderr,
                                                       args.log_file)
           
           _is_parent = daemonizer(
               pid,
               stdout_goto=stdout,
               stderr_goto=stderr
           )
   
       job.run()
   ```
