Outerbounds

This guide will show you how to deploy a Panel app using Outerbounds, a platform for deploying Python applications. The guide assumes you have a basic understanding of how to create a Panel app and focuses on the deployment process using Outerbounds.

Setup

To get started working with Outerbounds download and install the CLI. This can be done with pipx install outerbounds or uvx outerbounds.

Once you have installed the CLI you need to configure it to be able to deploy your app. This is done by running outerbounds configure $TOKEN where token is found in the Outerbounds dashboard under Setup. To verify your configuration you can run outerbounds check.

Deploying a Panel App with Outerbounds

Create the following files in a directory and then deploy to outerbounds app deploy --config-file config.yaml.

# config.yaml
name: panel-app
port: 6000
image: python:3.11-trixie

commands:
  - panel serve app.py --port 6000 --allow-websocket-origin="*.outerbounds.com"

environment:
  BOKEH_RESOURCES: CDN

# app.py
import panel_material_ui as pmui

pmui.Page(title="Hello World").servable()

# requirements.txt
panel
panel-material-ui

Note

The *.outerbounds.com wildcard in --allow-websocket-origin matches any app subdomain assigned by Outerbounds, but only one level deep, e.g., myapp.outerbounds.com and not myapp.dev.outerbounds.com.
