Pulumi Python SDK

https://www.pulumi.com/docs/reference/pkg/python/pulumi/

The SDK is available as a pip package.

Python Pulumi and Virtual Environments

A new Python project created with pulumi new will have a virtual environment created in a venv directory with required dependencies from requirements.txt installed in it. This behavior is controlled by the virtualenv runtime option in Pulumi.yaml:

runtime:
  name: python
  options:
    virtualenv: venv

virtualenv is the path, relative to the project directory, to the virtual environment to use.

Adding a New Dependency

To install a new dependency in the virtual environment, add the entry to requirements.txt and run in the project directory:

venv/bin/pip install -r requirements.txt
