Bjoern Django Final

wsgi_bjoern.py

import bjoern

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app.settings')
app = get_wsgi_application()

            pass
        exit()

   # Once first is dead, kill the others and exit with error code.
    pid, xx = os.wait()

finally:

Can you help me in how to run this on command line? Or in any deployment with nginx?

Hi Friend, how can I help you with that? @arunthomaspuc

In time: Today I don't use this approach anymore as it is a vertical scaling approach (more threads/processes); Currently, I tend to scale horizontally through a high number of containers which only needs lines 1-14.

Thank you so much for your fast reply.
Are you running with Bjoern on Kubernetes along with Django?
I wanted help in setting Bjoern up to serve my django application.

I mean after creating this wsgi_bjoern.py How or where do we invoke it?
Using gunicorn we use gunicorn mysite.wsgi bind 0.0.0.0:80
How do we invoke in case of Bjoern?

Put wsgi_bjoern.py in your django application root, adjust line 7 and use python wsgi_bjoern.py to start your django app.

Are you running with Bjoern on Kubernetes along with Django? Yeah, just be sure to put and NGINX on front of django containers and that's it.

ctrl+C doesn't close the server. The server only closes on container exit. Any help?

@phacic Are u using it in a container?

If you're using it on a container, remember to add a tty: true to allow the KeyboardInterrupt to be passed to the script, otherwise use exec wsgi_bjoern.py as your entrypoint/cmd to maintain the same behavior.

@gcavalcante8808 yes, am using it in a container.

Will give it a try and let you know the results. Thanks

Amazing ))) 17K PRS on M1 laptop using Bjoern and 400RPS with 50% of "connection interrupt" and timeouts with Gunicorn )))

i havent seen this server as option between others (gunic, uwsgi...), has someone used it in production ?

@lyf2000 I have used it 3 years ago with success. I didnt know how it goes in these days since I've been working with java and php lately =(
