Backend.AI WebUI Host

Backend.AI Web Server

A webapp hosting daemon which serves our webui as a SPA and proxies API requests

Installation

Prepare a Python virtualenv (Python 3.9 or higher) and a Redis server (6.2 or higher).

$ git clone https://github.com/lablup/backend.ai-webserver webserver
$ cd webserver
$ pip install -U -e .
$ cp webserver.sample.conf webserver.conf

Mode

If service.mode is set "webui" (the default), the webserver handles PWA-style fallbacks (e.g., serving index.html when there are no matching files for the requested URL path). The PWA must exclude /server and /func URL prefixes from its own routing to work with the webserver's web sessions and the API proxy.

If it is set "static", the webserver serves the static files as-is, without any fallbacks or hooking, while preserving the /server and /func prefixed URLs and their functionalities.

If you want to serve web UI in webserver with "webui" mode, prepare static web UI source by choosing one of the followings.

Option 1: Build web UI from source

Build backend.ai-webui and copy all files under build/bundle into the src/ai/backend/web/static directory.

Option 2: Use pre-built web UI

To download and deploy web UI from pre-built source, do the following:

cd src/ai/backend/web
curl --fail -sL https://github.com/lablup/backend.ai-webui/releases/download/v$TARGET_VERSION/backend.ai-webui-bundle-$TARGET_VERSION.zip > /tmp/bai-webui.zip
rm -rf static
mkdir static
cd static
unzip /tmp/bai-webui.zip

Setup configuration for webserver

You don't have to write config.toml for the web UI as this webserver auto-generates it on-the-fly.

Edit webserver.conf to match with your environment.

Usage

To execute web server, run command below. (for debugging, append a --debug flag)

$ python -m ai.backend.web.server
