Pyplines Python Library

The Pyplines Python library provides the Action author SDK and invocation shim. The separate pyplines-builder application builds images and Distributions.

from pyplines import Context, Input, Output


class GreetingInput(Input):
    name: str


class GreetingOutput(Output):
    message: str


def handler(i: GreetingInput, ctx: Context) -> GreetingOutput:
    ctx.log.info("Building greeting", name=i.name)
    return GreetingOutput(message=f"Hello, {i.name}!")

Action projects use a standard Python build backend such as setuptools and declare exactly one handler entry point in [project.entry-points."pyplines.action"]. pyplines-builder installs the package and this SDK inside the target image, validates the handler, and embeds its input/output schemas. The former Action Package build backend has been retired to legacy/action-builder/sdk-package. See example/v1alpha1/distributions/hello-world for the current authoring shape.

The public author API is:

from pyplines import ArtifactRef, Context, Error, Input, Output
