How to set up Nginx reverse proxy for local Docker Django

Question content

I am developing a docker project using nginx and django services. I have parameterized django.conf.template to dynamically pass environment variables based on the environment.

django.conf:

upstream django_app {
  server  ${django_private_ip}:${django_port};
}

server {

  listen  80;
  listen  443 ssl;
  listen  [::]:443 ssl;
  server_name   ${nginx_server_name};

  ssl_certificate /etc/nginx/certs/elitecars_cert.pem;
  ssl_certificate_key /etc/nginx/certs/elitecars_privkey.pem;

  access_log /var/log/nginx/nginx.django.access.log;
  error_log /var/log/nginx/nginx.django.error.log;

  location / {

    proxy_set_header    x-forwarded-host   $host;
    proxy_set_header    x-forwarded-server $host;
    proxy_set_header    x-forwarded-for    $proxy_add_x_forwarded_for;
    proxy_set_header    x-forwarded-proto  $scheme;
    proxy_set_header    x-real-ip          $remote_addr;
    proxy_set_header    host               $host;

    proxy_redirect  off;
    proxy_pass  http://django_app;
  }
}

The template works fine because I can view the environment variable values ​​using the more /etc/nginx/conf.d/sites-available/django.conf command

upstream django_app {
  server  django:8000;
}

server {

  listen  80;
  listen  443 ssl;
  listen  [::]:443 ssl;
  server_name   0.0.0.0 127.0.0.1 localhost;
  ...

But when I try to access via browser it doesn't work.

Any ideas? Can anyone help me?

Correct answer

On local and mac, I need to add host.docker.internal ip to /etc/hosts of nginx configuration file as shown below ：

127.0.0.1        localhost
172.17.0.1       localhost
...

and solve the problem.
