Nginx with script-server in a docker container

[klaertus]

I have an issue with my configuration and Nginx. I have a server with multiple Docker containers running different web applications. Let's say the server domain name is examplescriptserver.com. I also have an Nginx reverse proxy installed directly on the server (not in a Docker container) that routes to these applications, such as code-server, and it works well. However, I'm having an issue with script-server when it's in a Docker container (when it's installed directly on the server, it works fine). When I'm accesing to https://examplescriptserver.com/example1/, I get redirected to127.0.0.1:5000/index.html.

I've also tried changing the proxy_pass to the docker's internal ip (172.0.18.2), but in this case, it redirects me to that ip.

Here's my server configuration

My Nginx configuration:

server {
    listen 80 default_server;
    server_name examplescriptserver.com;
    return 301 https://$host$request_uri;
}

server {
    server_name examplescriptserver.com;

    # Script-server
    location ^~ /example2/ {
        proxy_pass_header Server;
        proxy_set_header Host $proxy_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:5000/;

        # needed for websockets
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Origin http://$proxy_host;
    }

    # code-server
    location /example1/ {
        proxy_pass http://localhost:1234/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
    }

    listen [::]:443 ssl;
    listen 443 ssl;
    ssl_certificate /etc/ssl/cert.pem;
    ssl_certificate_key /etc/ssl/key.pem;
}

And my Docker Compose file for Script-server is:

services:
    script-server:
        ports:
            - 127.0.0.1:5000:5000
        volumes:
            - '/var/run/docker.sock:/tmp/docker.sock:ro'
            - '/opt/script-server/conf/.htpasswd:/app/conf/.htpasswd'
            - '/opt/script-server/conf/conf.json:/app/conf/conf.json'
            - '/opt/script-server/runners/:/app/conf/runners'
            - '/services/scripts/:/app/scripts/'
        restart: always
        logging:
            options:
                max-size: 1g
        container_name: script-server
        image: 'bugy/script-server:latest'

Thanks for any help

Hi @klaertus, could you try to do one of the following things:

1. Add proxy_set_header X-Scheme $scheme; directive to Script server nging configuration
2. Change script server code as per https://github.com/bugy/script-server/issues/640#issuecomment-1485589667

You can try either 1 or 2. Or both of them together.

To be honest my network/protocol knowledge is not very high, and I don't know how those redirects are supposed to work, so I don't have clear understanding, how nginx handles those (and why it doesn't substitute paths properly)

Hello @bugy,

Just changing the code like https://github.com/bugy/script-server/issues/640#issuecomment-1485589667 solved my problem.

Thanks !

Thanks for confirming @klaertus. Did you try setting X-Scheme?

[klaertus]

Yes, but whether I set it or not didn't make any difference.

I see, thanks!
