Setting up behind reverse proxy at /pgwatch/, /pgwatch/grafana requires modifying all static file paths in html.

[Teut2711]

Hi, I am setting Pgwatch up behind a reverse proxy with nginx as follows.

Main dashboard:

For the main dashboard running at 8080, I tried to edit the web.py by replacing line https://github.com/cybertec-postgresql/pgwatch2/blob/master/webpy/web.py#L446
with
cherrypy.quickstart(Root(), "/pgwatch", config=config)

The dashboard opens at https://myhost.com/pgwatch but when I inspect the html in browser, I get this.

To what I know about web, the base url is attached to the /static/bootstrap-4.3.1-dist/css/bootstrap.min.css to form
{base_url}/static/bootstrap-4.3.1-dist/css/bootstrap.min.css to get the css file but what the expectation is that the css file should be requested from {base_url}/pgwatch/static/bootstrap-4.3.1-dist/css/bootstrap.min.css.
So one way to fix this is to change all the href's in the html file. But that isn't a good solution.

Grafana:

Also I changed root_url in

/usr/share/grafana/conf/defaults.ini

to

root_url = %(protocol)s://%(domain)s:%(http_port)s/pgwatch/grafana . For grafana, this didn't work. I got 502.

My nginx.conf file looks like this.

server {

  # listen 80;
  listen 443 ssl;
...
  ssl_protocols TLSv1.2 TLSv1.3;
  ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
  ssl_prefer_server_ciphers off;

  ssl_dhparam /etc/dh/nginx.pem;


  location /pgwatch/grafana {
    proxy_pass http://pgwatch:3000;
    proxy_http_version 1.1;
    proxy_set_header Host $http_host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

  }
  location /pgwatch {
    proxy_pass http://pgwatch:8080;
    proxy_http_version 1.1;
    proxy_set_header Host $http_host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

  }

}

Please help with both the problems.
