Configure Nginx with two docker-compose containers (Flask and Django) - django

Question

I am trying to expose two different address used like APIs. One in Django and the other one in Flask, they are Docker-compose containers.
I need configure Nginx for expose the two containers in two different subdomains.
It is my Nginx.conf:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024; ## Default: 1024, increase if you have lots of clients
}
http {
include /etc/nginx/mime.types;
# fallback in case we can't determine a type
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;
#tcp_nopush on;
keepalive_timeout 65;
upstream app {
server django:5000;
}
upstream app_server {
server flask:5090;
}
server {
listen 5090;
location / {
proxy_pass http://app_server;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Scheme $scheme;
}
}
server {
listen 5000;
location / {
proxy_pass http://app;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Scheme $scheme;
}
}
}
And my production.yml
Nginx:
build: ./compose/production/nginx
image: *image
ports:
- 80:80
depends_on:
- flask
- django
My containers are all up.

Answer 1

I use proxy_pass:
server {
listen <port>;
location / {
proxy_pass http://<container-host-name>:<port>;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Scheme $scheme;
}
}
You nginx container connected only with 80 port on machine and 80 port on container, but you nginx server listen 5000 and 5090 ports :)
