Hello, I've been working on developing an API with Flask and Automation API lately. During my research, I encountered some challenging aspects that couldn't be resolved with a simple online search or by referring to the documentation. Therefore, I've turned to you for assistance. My idea is quite straightforward – I plan to create multiple files containing the resource creation code (by example, for Datadog i would create monitor.py, slo.py, etc), with the routes located in app.py. Users may then use a curl command to access this API. I shouldn't require Pulumi Cloud, but it seems that without a main.py file automation api in python doesn't works, and if i use a main.py file I am unable to select the resource to create.. Is what I am experiencing like this or should I be able to do what I want to do? Thank you in advance!

In any case if you want to define your resources in separate files - turn them into modules

and put your "create" "program" (the one which calls to
pulumi.*
to create resources) there

You can use your custom backend like this:
Copy code
PULUMI_PROJECT_NAME = "my-service"
PULUMI_BACKEND = "s3://<bucket>/<path>"
PULUMI_SECRETS_PROVIDER = "<awskms://alias/><pulumi-key>?region=eu-north-1"

def runner(count: int):
    for i in range(count):
        ec2.Instance(f"instance-{i}")
        ...
            

def deploy_runners(name: str, count: int, config: dict):
    stack = create_or_select_stack(
        stack_name=name,
        project_name=PULUMI_PROJECT_NAME,
        program=partial(runner, count),
        opts=LocalWorkspaceOptions(
            project_settings=ProjectSettings(
                name=PULUMI_PROJECT_NAME,
                runtime="python",
                backend=ProjectBackend(PULUMI_BACKEND),
            ),
            secrets_provider=PULUMI_SECRETS_PROVIDER,
            stack_settings={
                name: StackSettings(secrets_provider=PULUMI_SECRETS_PROVIDER)
            },
        ),
    )
    stack.set_all_config(
        {f"{PULUMI_PROJECT_NAME}:{k}": ConfigValue(v) for k, v in config.items()}
    )

    result = stack.up(on_output=print, color="always")

Look Yuri, what i said, i took like example self-service-platyform that has no main.py file and Pulumi shows me this error: error: unable to find main python program `__main__.py I don't know why, and this causes that every resource has to be called from main.py file and this execute every creation of resource

My guess would be that you're trying to run
pulumi up
. When using automation you don't run pulumi directly. You run your script.
