Configure Nginx Proxy for self hosted Supabase

I have trouble setting up Nginx Proxy for self hosted Supabase. The prompt for the Supabase login is appearing but after entering the credentials, it will show 404. Here is the nginx conf file, where actual domain name is replaced by example.com

server {
    listen 80;
    listen [::]:80;

    server_name example.com;

    location / {
        proxy_pass http://127.0.0.1;
        include proxy_params;
    }

    location /supabase {
        proxy_pass http://127.0.0.1:8000;
        include proxy_params;
    }

    location /websurvey {
        proxy_pass http://127.0.0.1:1200;
        include proxy_params;
    }
}

I have a public IP address and was also given a domain name. This server will host several Docker containers so I chose to make them accessible through subdirectories.

What are the configurations that I need to do in the Supabase .env and/or in other config files? There was no issue if I use http://<IP_ADDRESS>:8000 or http://<DOMAIN_NAME>:8000, I can log in Supabase, but if I use http://<DOMAIN_NAME>/supabase, as mentioned, the login prompt will show. And after I entered the credentials it will go 404.

Also, this the Web Survey App is a Flutter Web Application, in the initialization, I would like to use the http://<DOMAIN_NAME>/supabase. And I will also install SSL certificates from Let’s Encrypt later after I fixed this.

Thanks in advance!

    I’m not sure if you’ve already figured this out, but leaving this here anyways.

    As you’ve not shared any information on your Docker configuration, it’s difficult to say but I suspect the issue lies in the docker network (I would leave a comment instead, but I’m a newer user and so I don’t have the rep points yet).

    If your containers are all on the default Docker bridge network, then that would explain why your nginx configuration doesn’t work. You should use the service name instead as the hostname (Docker’s embedded DNS server will handle the lookup).

    Here’s an example Docker compose file (many fields removed for brevity):

    services:
  nginx:
    ports:
      - 80:80 # expose port 80 to host, listening internally on port 80
    networks:
      - my_bridge
  app:
    # listening on port 80
    networks:
      - my_bridge

  kong: # Supabase services sit behind kong (see their docs)
    # listening on port 8000
    networks:
      - my_bridge
  websurvey:
    # Your custom web survey docker container (listening on port 1200)
    networks:
      - my_bridge

networks:
  my_bridge:
    driver: bridge # default driver

    The reason you get a 404 when visiting /supabase is because nginx proxies that route to localhost, which remains within the nginx container and therefore fails since port 8000 doesn’t serve anything inside nginx.

    You can imagine each container as a separate computer on a local network. So, to access the other containers, you would need to change your nginx configuration to reference services instead:

    location / {
  proxy_pass http://app:80;
  include proxy_params;
}
location /supabase {
  proxy_pass http://kong:8000;
  include proxy_params;
}

location /websurvey {
  proxy_pass http://websurvey:1200;
  include proxy_params;
}

    Alternatively, if it suits your need, you could set the Docker network (my_bridge) to the host driver and reference everything with localhost, but then you would have to move your app off of port 80 (since nginx listens on port 80). I’d prefer the bridge network here. The code above is not tested, but should work in theory.

    you nginx config must be this as per your settings:

    server {
    listen 80;
    listen [::]:80;

    server_name example.com;
    
    #i dont know why you are keeping this but
    location / {
        proxy_pass http://127.0.0.1;
        include proxy_params;
    }
    #and  use this, you can simply delete the path and serve this settings in / as well
    location /supabase {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /websurvey {
        proxy_pass http://127.0.0.1:1200;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

    i am not sure why you are not serving it in / and instead choose to use /supabase , on top of that you are keeping both. i have no idea why but

    you can simply do this:

    server {
    listen 80;
    listen [::]:80;

    server_name example.com;
    
  
    location /{
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /websurvey {
        proxy_pass http://127.0.0.1:1200;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

    if you set this you will just have to enter your domain name mapped witht he ip of the instance hosting this and you can access it
