Async Python program entrypoints with pulumi.run

Pulumi Python programs can now use an async entrypoint. Pass a zero-argument async function to pulumi.run in your __main__.py, and the runtime awaits it on the program’s event loop. This makes it easier to call async functions while retaining a linear program flow:

import pulumi

async def main() -> pulumi.Inputs:
    value_a = await some_async_operation()
    value_b = await some_other_async_operation()
    return {"value_a": value_a, "value_b": value_b}

pulumi.run(main)

If the entrypoint returns a mapping, each entry is registered as a stack output, merging with any explicit pulumi.export calls using the normal export behavior. The entrypoint can also return None and call pulumi.export directly.

pulumi.run may be called only once per program, and existing synchronous programs keep working unchanged. For details, see the async entrypoint documentation.
