This guide is for Beta9, the open-source and self-hosted version of Beam. If you are looking for the cloud-hosted version of Beam, you can find that here.

​
Setting up the server

k3d is used for local development. You’ll need Docker and Make to get started.

To use our fully automated setup, run the setup make target.

This will overwrite some of the tools you may already have installed. Review the setup.sh to learn more.

make setup

​
Setting up the SDK

The SDK is written in Python. You’ll need Python 3.8 or higher. Use the setup-sdk make target to get started.

This will install the Poetry package manager.
make setup-sdk

​
Using the SDK

After you’ve setup the server and SDK, check out the SDK readme here.

​
Example App

from beta9 import function


@function(cpu=8)
def square(i: int):
    return i**2


def main():
    numbers = list(range(10))
    squared = []

    # Run a remote container for every item in list
    for result in square.map(numbers):
        squared.append(result)
