You can easily deploy Streamlit apps on Beam. In this guide, we’ll show you how to deploy a simple Streamlit app that visualizes a simple dataset.

See the code for this example on Github.

​
App Structure

There are two components to deploying a Streamlit app on Beam:

  1. An start_server.py file with your Beam code. You can view the source code here.
  2. A app.py file that hosts the Streamlit app

Here’s what the Beam-specific code looks like:

start_server.py
from beam import Image, Pod

streamlit_server = Pod(
    image=Image().add_python_packages(["streamlit", "pandas", "altair", "requests"]),
    ports=[8501],  # Default port for streamlit
    cpu=1,
    memory=1024,
    entrypoint=["streamlit", "run", "app.py"],
)

res = streamlit_server.create()

print("✨ Streamlit server hosted at:", res.url)

​
Deployment

To run the app, you can simply invoke the Python module directly:

python start_server.py

Running this command will print the URL of the Streamlit app to the console.
