Nginx caching of uwsgi served static files - django

Question

The django project is deployed using uwsgi as application server, it also serves static files from a specified directory(as shown in the below command) and nginx is used as reverse proxy server. This is deployed using docker.
The uwsgi command to run the server is as follows:
uwsgi -b 65535 --socket :4000 --workers 100 --cpu-affinity 1 --module wui.wsgi --py-autoreload 1 --static-map /static=/project/static;
The application is working fine at this point. I would like to cache the static files into nginx server. So i have referred blog https://www.nginx.com/blog/maximizing-python-performance-with-nginx-parti-web-serving-and-caching and i have included following configuration in my nginx.conf :
location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg
|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid
|midi|wav|bmp|rtf)$ {
expires max;
log_not_found off;
access_log off;
}
After adding this into my Nginx conf, the Nginx server container exits with the following error:
[emerg] 1#1: invalid number of arguments in "location" directive in /etc/nginx/nginx.conf:43
Is this how uwsgi served static files can be cached into nginx? If yes please suggest me what is gone wrong here.
My complete nginx.conf is as follows:
events {
worker_connections 1024; ## Default: 1024
}
http {
include conf/mime.types;
# the upstream component nginx needs to connect to
upstream uwsgi {
server backend:4000; # for a web port socket (we'll use this first)
}
# configuration of the server
server {
# the port your site will be served on
listen 8443 ssl http2 default_server;
# the domain name it will serve for
server_name _; # substitute your machine's IP address or FQDN
charset utf-8;
ssl_certificate /secrets/server.crt;
ssl_certificate_key /secrets/server.key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
add_header Strict-Transport-Security "max-age=31536000" always;
# Redirect HTTP to HTTPS
error_page 497 https://$http_host$request_uri;
# max upload size
client_max_body_size 75M; # adjust to taste
uwsgi_read_timeout 600s;
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass uwsgi;
include /config/uwsgi_params; # the uwsgi_params file you installed
}
location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg
|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid
|midi|wav|bmp|rtf)$ {
expires max;
log_not_found off;
access_log off;
}
}
}
Nginx version: 1.16

Answer 1

The problem with your config is that the location block has newlines in the list of filenames. I tried nginx -t -c <filename> with a modified version of your location block:
location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
expires max;
log_not_found off;
access_log off;
}
... and this passes the test!
