When I run the flask server in local machine, I use this code
app.run(host='0.0.0.0', port=port,debug=False,use_reloader=False)
I am using BackgroundScheduler so I need reloader to be false othrwise BackgroundScheduler will run twice.
from apscheduler.schedulers.background import BackgroundScheduler
When I deploy to Heroku, I use gunicorn like this
web: gunicorn app:app
So the problem is that reloader is true when using this so BackgroundScheduler has two instances.
So how do I stop reloader for Gunicorn?
Any help will be appreciated.
As you can see in above image 2 processes are created.
Thank you in advance
You can just provide the same arguments as command line arguments in heroku:
web: gunicorn app:app --reload=False
This does provide an answer to your question, but it won't solve the issue, as the default value for --reload
is already False
. You can check that with gunicorn --help
.
I think you shouldn't use BackgroundScheduler
, but instead use the --daemon
flag. As per gunicorn --help
: -D, --daemon - Daemonize the Gunicorn process. [False]
-D, --daemon - Daemonize the Gunicorn process. [False]
. "To Daemonize" means run it as a background process.
