Ngnix Issue

This is a minimum, reproducible example for an issue I'm encoutering when deploying my gunicorn app to nginx.

Installation (Linux)

Webserver

in the /webserver directory, create a Python virtual environment python3 -m venv venv and activate it source venv/bin/activate then install all requirements from the requirements.txt file pip install -r requirements.txt

Make sure nginx is installed on your machine. Copy the webserver_nginx_conf file to /etc/nginx/sites-available directory. Then establish the symbolic link sudo ln -s /etc/nginx/sites-available/myproject /etc/nginx/sites-enabled. Perform the test command sudo nginx -t and then sudo systemctl restart nginx

Running without Nginx

Webserver:

(venv) /webserver$ gunicorn --worker-class gevent --workers 1 --timeout=160 --bind 0.0.0.0:5000 webserver:app

Go-Server:

/goserver$ go run main.go

When visiting http://localhost:5000 you should notice in the browser console that data is coming in and is being properly parsed.

Running with Nginx

Make sure Nginx is running Webserver:

(venv) /webserver$ gunicorn --worker-class gevent --workers 1 --timeout=160 --bind 0.0.0.0:5000 webserver:app

Go-Server:

/goserver$ go run main.go

Now when checking browser console, some responses should get truncated.
