Configurable context-path

[Tedlar]

I think it would be a great feature to add ability to configure web applications context-path (base path).
Of course as variable passed to docker container.
So you could change base url from:
http://localhost:8181
to:
http://localhost:8181/new-context

It would enable placing application behind reverse-proxy.

@Tedlar, you don't need additional context path to configure application behind reverse-proxy. There is example docker-compose.yml with traefik v2 as reverse proxy. No problem to configure using apache or nginx.

[Tedlar]

Still I have configuration problem.
On host machine I have already few applications.
Those applications are standing behind revers proxy (nginx) so I can access all of them through standard http(s) ports.
So http://my.server.com/app1 -> http://my.server.com:8000
I would like to have same configuration for your syncing app.

@Tedlar, could you show me your reverse proxy configuration?

[Tedlar]

@hlavki no problem.

        location /auth {
                rewrite ^auth(.*) /$1 break;
                proxy_pass http://localhost:8183;
                proxy_set_header Host $host:$server_port;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

@Tedlar I am not NGINX expert, but couple of thoughts:

• Why are you using 8183 port number when default port is 8181
• What I read in nginx reverse proxy documentation, this should work:

location /auth/ {
    proxy_pass http://localhost:8181;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

[Tedlar]

Nope, not working.
All css and js files are being fetched using wrong path (without '/auth').
I also added configuration:

location / {
  if ($http_referer ~ "^https?://[^/]+/auth"){
    rewrite ^/(.*) http://$http_host/auth/$1 redirect;
  }
}

Thanks to that application is being loaded properly.
Still 'Redirect url' is messed up. Damn.

@hlavki For now i moved your app to base url ('/') and everything works.
I hope that in near future I will be able to move it to proper path ('/auth/')

[hlavki]

yes, I understand your problem. I will let you know if I found some solution.
