gunicorn okuduğundan itibaren birden çok iş parçacığı oluşturulmasına izin verir, bu da beni iş parçacığının hata noktasını kullanan aynı bağlantı noktasına erişmeye çalıştığını düşünmeme neden oluyor. Ancak, nasıl çözeceğimi bilmiyorum, herhangi bir yardım takdir edilir.

Answer 1

Uygulama çağırıyor gibi görünüyor: uygulama yerine flaskapp: flaskapp ve run.py başka bir örneği açmaya çalışıyor.

16:35:44 web.1 | File "/home/adminuser/Desktop/Github/SoftwareEng/barcodeServer/SoftwareEng/run.py", line 3, in <module> 

Birincisi, her zaman koşmak encapsulate:

if __name__ == '__main__': 
    flaskapp.run(debug=True) 

Ve çağırmak için procfile güncellemek app.__init__.py yerine:

web: gunicorn app:flaskapp --log-file=- 

ps: Ben ne procfile veya Foreman bilmiyorum - Kahramanca şeyler?
