I'm trying to get django (on gunicorn) and nginx running with docker. Unfortunately, I keep getting a Bad Request (400) error after I run docker-compose up -d --build. Help.
I have tried changing directories, directory names, volumes, networks and exposed ports to no avail. I also tried adding and removing server_name in my nginx.conf file.
In settings.py I have:
DEBUG = False
ALLOWED_HOSTS = ['127.0.0.1', 'localhost']
This is my docker-compose.yml file:
version: '3.3'
services:
web:
build: ./app
command: gunicorn my_server.wsgi:application --bind 0.0.0.0:8000
volumes:
- ./app/:/usr/src/app/
expose:
- 8000
environment:
- DATABASE=${DATABASE}
- SECRET_KEY=${SECRET}
- SQL_DATABASE=${POSTGRES_USER}
- SQL_ENGINE=django.db.backends.postgresql
- SQL_HOST=${POSTGRES_HOST}
- SQL_PASSWORD=${POSTGRES_PASSWORD}
- SQL_PORT=${POSTGRES_PORT}
- SQL_USER=${POSTGRES_USER}
- SU_NAME=${SU_NAME}
- SU_EMAIL=${SU_EMAIL}
- SU_PASSWORD=${SU_PASSWORD}
depends_on:

logging:

options:
max-size: "100k"
max-file: "20"
volumes:
static_volume:

external: true
and this is my nginx.conf file:
upstream my_server {
server web:8000;
}
server {
listen 80;
location / {
proxy_pass http://my_server;
proxy_set_header Host $http_host;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_redirect off;
}
location /assets/ {
alias /usr/src/app/assets;
}
location /robots.txt {
alias /var/www/html/robots.txt;
}
}
In my Dockerfile for django, I run makemigrations and migrate and I have confirmed that the database tables are created.
I expect to go to localhost or 127.0.0.1 and see my website served there. Instead, I get this error: Bad Request (400).
When I run docker ps I get:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

When I run docker logs my_server_nginx_1 I get lines like this:

Probaly you need to add my_server to your allowed hosts(same as your upstream in NGINX config):
ALLOWED_HOSTS = ['my_server']
While trying to implement upinder kumar's solution I stumbled upon the solution. I will add here for anyone else facing this problem in the future:
The nginx.conf cannot have both
proxy_set_header Host $http_host;
and
proxy_set_header Host $host;
Deleting either one solved the problem.
Create socket file using gunicorn and configure in our virtual host.
#############Gunicorn configuration###################
[unit]
Description=gunicorn daemon
After=network.target
[Service]
User=root
Group=nginx
WorkingDirectory=/var/www/html/source
ExecStart=/var/www/html/env_source/bin/gunicorn --workers 3 --bind
unix:/var/www/html/source/source.sock application_name.wsgi:application
[Install]
WantedBy=multi-user.target
It will create file name source.sock just configure this sock file in nginx virtual host
###########nginx Configuratio
server {
server_name example.com;
listen 80;
access_log /var/www/html//source/access.log;
error_log /var/www/html/source/error.log;

location /static/ {

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $host;
}
}
if you define allowed hosts in settings.py:
ALLOWED_HOSTS = ['localhost','127.0.0.1','my_domain.com']
if you define allowed hosts in .env as an environment
variable, you should use the following format (without brackets):
in .env file:
DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 my_domain.com
and in settings.py
ALLOWED_HOSTS = os.getenv("DJANGO_ALLOWED_HOSTS", "127.0.0.1").split()

I am running a Django app on Docker with Nginx, the configuration works perfectly locally but on the server, it doesn't.
i get the error 502 Bad Gateway in the web page
and the logs I get

now i am not understanding why this is happening and how do i solve this
Basically, I am trying to get access to MariaDB on the website. I needed to run a docker container so that it looks as if its network requests originate from the instance on which it runs (AWS Ubuntu Instance). For that, I used network_mode: "host" within my docker-compose file for each container. Also, I had to comment out the port bindings since they are not compatible with host network mode. However, now I get:
Connection refused error. I believe I have to change something within the nginx config file which is project.conf, but I am not sure what.
This is the docker-compose file:
version: '3'
services:
app:
restart: always
build: ./app
#ports:
# - "8501:8501"
env_file:
- .env
command: streamlit run Main.py
network_mode: "host"
mariadb:
image: mariadb:10.9.3
#ports:
# - "3306:3306"
volumes:
- db_data:/var/lib/mysql
- db_conf:/etc/mysql/conf.d
environment:
MYSQL_ROOT_PASSWORD: "xxx"
MYSQL_DATABASE: "xxx"
MYSQL_USER: "xxx"
MYSQL_PASSWORD: "xxx"
MYSQL_ROOT_HOST: "xxx"
network_mode: "host"
nginx:
restart: always
build: ./nginx
#ports:
# - "80:80"
depends_on:
- app
- mariadb
volumes:
db_data:
db_conf:
And, this is the project.conf file:
server {
listen 80;
server_name helloworld-st-app;
location / {
proxy_pass http://app:8501/;
}
location ^~ /static {
proxy_pass http://app:8501/static/;
}
location ^~ /healthz {
proxy_pass http://app:8501/healthz;
}
location ^~ /vendor {
proxy_pass http://app:8501/vendor;
}
location /stream {
proxy_pass http://app:8501/stream;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
}
}
I tried removing 8501 from the url, still nothing. Any help on this would be much appreciated. Thanks in advance.
I am working on my django + nginx + docker-compose project

UPDATE
I was trying to replace proxy_pass http://django:8000; with proxy_pass http://app; but it didn't help
Value of proxy_pass is incorrect.
When you're referencing an upstream group, you've to pass the name of the group to proxy_pass.
In your case, the name of upstream group is "app". So the value of proxy_pass should look like this:
proxy_pass http://app;
I am trying to define a production env for Django using docker and Nginx and Gunicorn and It works fine when debug=True If I make debug=False the Issue start here gives me Bad Request (400)
my Nginx file like this:
upstream API {
server backend-stack:8000;
}
server {
listen 80;
server_name localhost;
location / {
proxy_set_header Host $host;
proxy_pass http://api;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Real-IP $remote_addr;
}
location /static/ {
alias /backend/static/;
}
location /media/ {
alias /backend/media/;
}
}
my allowed_hosts In settings.py
if env.get("ALLOWED_HOSTS"):
ALLOWED_HOSTS = env.get("ALLOWED_HOSTS")
my gunicorn execute command from entrypoint.sh file:
gunicorn core.wsgi:application --bind 0.0.0.0:8000
also here Is my nginx container In docker-compose:
nginx:

build: ./nginx

ports:

- 443:443
depends_on:
- backend
networks:

my allowed_hosts value:
ALLOWED_HOSTS = ['localhost', '127.0.0.1', '0.0.0.0', '*']
finaly access log file for nginx :

ok, I did It the problem was happening because I don't create any view yet or any page with a URL after I create a new page and set it as the home page It's working now.
