[Feature Request]: deploy webui on a base_url/subpath instead of /

[shuaiyy]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

I want to deloy webui on an exist host with subpath, like http://xxx.com/webui/

I tried nginx to for service route，not work.

Proposed workflow

1. start webui with args --base-url /webui
2. got the service on http://host:port/webui/

This used to work when I first installed SD but now with the new version it doesn't work, not sure what version changed the support

[marsplant]

I met the same problem, have you solved this?

[AaronWebster]

What would one need to do to make this change?

[simonbermudez]

Hey @shuaiyy @marsplant @AaronWebster I found a way of doing it.

I found this PR that includes the change #9865

so In order to implement those changes you only have to switch to the dev branch and then add this to your webui-user.sh

export COMMANDLINE_ARGS="--subpath=/yoursubpath"

[akx]

Yep, --subpath is now also available on the current master (v1.3.0).

[Dewey-Ding]

it not work on the current master .

fix linter issue for 1.3.0

@Dewey-Ding What does not work? What did you try?

[Dewey-Ding]

use this cmd " --subpath aip --skip-torch-cuda-test --no-half " on current master

the previous --subpath i implemented was just a workaround as gradio didnt have proper support, i have updated it after they added root_path in 3.30. you can checkout #11478

[jianbohuang]

In recently gradio version , if you need access gradio from nginx proxy and your gradio not configures a base-url path, it will raise a theme.css 404 not find , or an /info 404 not find.
you can follow this guide for the nginx configuration (https://www.gradio.app/guides/running-gradio-on-your-web-server-with-nginx)

--subpath args no work in SD v1.30，

fix:

1. upgrade gradio to 3.36.1 or down to 3.29.0 (there are some bug)
2. add an root_path="/gradio-demo" at there:

   stable-diffusion-webui/webui.py

   Line 390 in 394ffa7

   app, local_url, share_url = shared.demo.launch(

3. remove arg --subpath
4. access with you inverse proxy with path "/gradio-demo"

I tried this same method, but the browser shows {"detail":"Not Found"}.

[catalpaaa]

I tried this same method, but the browser shows {"detail":"Not Found"}.

a fix was merged, now you can do --subpath your-path with location /your-path/ { proxy_pass http://localhost:your-port/; } in nginx

[keisukenakamurafc]

When I clone Master and run it with the following conditions, the result is still the same: {"detail": "Not Found"}.
If you know where I am wrong, I would appreciate it if you could let me know.
The reverse proxy seems to be functioning properly.

• COMMANDLINE_ARGS
  export COMMANDLINE_ARGS="--subpath=/stablediffusion-webui --listen --no-gradio-queue"
• Run-time commands
  python3 launch.py --subpath=/stablediffusion-webui --listen --no-gradio-queue
• .conf of nginx

    listen 80;
    location /stablediffusion-webui{
        proxy_pass http://xxxxxxxxxx:7860;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
}

    }

    access_log /var/log/nginx/access.log;

    error_log /var/log/nginx/error.log;

}

proxy_pass http://xxxxxxxxxx:7860; can you explain this line, if you are running webui on the same machine, you should have a proxy to localhost:7860. If not then please double check if you can access the address directly first.

[keisukenakamurafc]

It is running on a remote GPU server and "xxxxxxxxxxxx" is marked with an ip address. It has been hidden for security reasons. If no sub-path is attached, it is accessed normally.

[keisukenakamurafc]

Thank you. I can't seem to do it even with "proxy_pass http://xxxxxxxxxx:7860/stablediffusion-webui/".
It's most likely due to gradio or complex dependencies.

I would try and setup the reverse proxy on the GPU server and see if its posible to route back to whatever server you are using.

Adding proxy rewrites in NGINX and launching/starting with the subpath parameter was enough to resolve this. Assuming you want to serve this over subpath /stable:

On your NGINX conf:

location /stable {
    auth_request /oauth2/auth;
    error_page 401 = /oauth2/sign_in;

    proxy_set_header Host $host;

    proxy_pass http://192.168.0.10:7860/;
    rewrite /stable/(.*) /$1 break;
    proxy_redirect off;


    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Scheme $scheme;
    proxy_buffers 4 256k;
    proxy_buffer_size 128k;
    proxy_busy_buffers_size 256k;

}

Startup:

cd /opt/stable-diffusion-webui
./webui.sh --listen --subpath=/stable

[keisukenakamurafc]

I have resolved this issue! Thank you to everyone!

[David19910809]

I have resolved this issue! Thank you to everyone!
can you tell me how to resolved

[AlpTuncay]

Has anyone solved this issue? I am trying to serve this on Kubernetes cluster behind a Virtual Service under a subpath. When I change the root_path of the Gradio application with --subpath option I get the error below

My Gradio version is 3.41.2

If solved, can anyone point me in the right direction?

[chillFFF]

By upgrading fastapi to version 0.110.3, I resolved this issue.（gradio==4.40.0）
