ParaviewWeb behind Nginx

Hi everyone!

I have troubles getting a setup with paraview to work behind a nginx container. When I got to http://0.0.0.0/visualizer my connection times out.

My Docker stack:

version: "3.8"

services:
  paraview:
    image: kitware/paraviewweb:pvw-egl-demo-v5.6.0
    command: "ws://localhost:9000/"
    entrypoint: "/opt/paraviewweb/scripts/start.sh"

  nginx:
    image: nginx:stable-alpine
    ports:
      - 80:80
      - 443:443
    volumes:
    - $HOME/pwtest/nginx/conf.d:/etc/nginx/conf.d/
    - $HOME/pwtest/nginx/nginx.conf:/etc/nginx/nginx.conf

I have the following nginx configuration files:

# conf.d/http.conf
resolver 127.0.0.11;

server {
    listen 80;
    server_name *;
    proxy_read_timeout 3600s;

    location ~ /ws {
        proxy_set_header Host $host;
        proxy_pass http://paraview:80;
    }

    location / {
        proxy_set_header Host $host;
        proxy_pass http://paraview:80;
    }

}

server {
    listen 9000;
    server_name *;
    proxy_read_timeout 3600s;

    location ~ / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Connection $connection_upgrade;
        proxy_pass http://paraview:9000;
    }

}

# nginx.conf
user  root;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    map $http_upgrade $connection_upgrade {
	       	default upgrade;
	       	''      close;
	}

    # Log format
    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
    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    # Set maximum file upload size
    client_max_body_size 500M;

    # Specific server blocks
    include /etc/nginx/conf.d/*.conf;

}

Did anyone successfully get paraview web to run behind nginx or can anyone see the issues with my setup? Thanks /Christian

On my local setup I can mix and match 0.0.0.0 and localhost. In the production settings I changed it to the right url. Locally I just used port 80 and http, so it worked as expected with ws. In production I use wss

Perfect, I just wanted to clarify for anyone using that as reference.
