I’m configuring Docker Nginx, but I keep encountering the following error:
nginx-1 | 2024/12/26 11:57:50 [emerg] 1#1: "worker_processes" directive is not allowed here in /etc/nginx/conf.d/nginx.conf:1
nginx-1 | nginx: [emerg] "worker_processes" directive is not allowed here in /etc/nginx/conf.d/nginx.conf:1
What I’m doing:
I’m trying to set up Nginx with Docker, and my setup includes three files:
- docker-compose.yml
- nginx/nginx.conf
- nginx/Dockerfile
Here’s the code I’m working with:
docker-compose.yml:
nginx:
build: ./nginx
volumes:
- static_volumes:/usr/src/app/_static
- media_volumes:/usr/src/app/_media
ports:
- 80:80
depends_on:
- web
web:
build: .
command: gunicorn daniel_blog.wsgi:application --bind 0.0.0.0:8000
volumes:
- static_volumes:/usr/src/app/_static
- media_volumes:/usr/src/app/_media
- ./:/usr/src/app/_media
expose:
- 8000
env_file:
- ./.env.prod
depends_on:
- db
db:
image: postgres:17.0-alpine
volumes:
- postgres_data:/var/lib/postgresql/data/
env_file:
- ./.env.prod.db
volumes:
postgres_data:
static_volumes:
media_volumes:
nginx/nginx.conf:
server {
listen 80;
server_name localhost;
# Default location
location / {
proxy_pass http://daniel_blog;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
# Static files
location /static/ {
alias /usr/src/app/_static/;
}
# Media files
location /media/ {
alias /usr/src/app/_media/;
}
}
nginx/Dockerfile:
RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d
The Problem:
I added worker_processes auto; at the top of my nginx.conf, but I keep getting the error:
nginx-1 | nginx: [emerg] "worker_processes" directive is not allowed here in /etc/nginx/conf.d/nginx.conf:1
Even when I remove worker_processes auto;, the same error persists.
I’m confused because I thought worker_processes should work in nginx.conf.
From the error log, it seems the file /etc/nginx/conf.d/nginx.conf is causing the issue.
I believe this is being referenced because of the COPY instruction in my Dockerfile.
My Understanding (and Questions):
I’ve read that worker_processes should only be in the main Nginx configuration file, like /etc/nginx/nginx.conf, not in /etc/nginx/conf.d/*.conf.
Is this correct? If so, how should I adjust my nginx.conf and Dockerfile to fix this issue?
Since I’m following a book tutorial, I don’t fully understand why this error occurs. Can you help me understand why worker_processes is not allowed in /etc/nginx/conf.d/nginx.conf?
Any help or guidance would be greatly appreciated!
Move worker_processes to the Main Configuration File
Instead of putting worker_processes in /etc/nginx/conf.d/nginx.conf, place it in the main nginx.conf file (/etc/nginx/nginx.conf) like below
server {
listen 80;
server_name localhost;
# Default location
location / {
proxy_pass http://daniel_blog;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
# Static files
location /static/ {
alias /usr/src/app/_static/;
}
# Media files
location /media/ {
alias /usr/src/app/_media/;
}
}
Update the Main nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
keepalive_timeout 65;
include /etc/nginx/conf.d/*.conf;
}
Modify the Dockerfile
FROM nginx:latest
COPY nginx/nginx.conf /etc/nginx/nginx.conf
COPY nginx/nginx.conf /etc/nginx/conf.d/nginx.conf
Rebuild Your Docker Container
docker-compose down
docker-compose up --build
