Pre-release

This release is a pre-release and may not be stable for production use.

Pyplines Python SDK

Python 3.14 typed Action handlers:

from pyplines.actions import Context, Inputs, Outputs

class EchoInputs(Inputs):
    message: str

class EchoOutputs(Outputs):
    message: str

def handler(inputs: EchoInputs, context: Context) -> EchoOutputs:
    context.log("Started")
    return EchoOutputs(message=inputs.message)

Declare handler = "my_action:handler" under [project.entry-points."pyplines.action"] in pyproject.toml. Use pyplines-action init, validate, test and push to build and publish the image with its captured schema. Actions execute synchronously; timeouts and container lifecycle belong to the runner.

Install pyplines[client] for from pyplines.client import Client. The operator CLI is a separate distribution, pyplines-cli.

Execution context and logs

Context exposes invocation_id, scratch_dir (temporary /tmp space), and log:

context.log("Action started")
context.log("Service restarted", level="info", service="payments", elapsed_ms=420)
context.log("Retrying connection", level="warning", attempt=2)
  • Levels are debug, info, warning, and error; explicit logs default to info.
  • Custom JSON-compatible attributes are nested under fields. Dictionary keys MUST be strings; numbers MUST be finite. Arbitrary Python objects are not serialized.
  • Messages MUST be at most 4,096 characters. Encoded fields MUST fit within 8 KiB; the complete JSON record MUST fit within 16 KiB. Invalid or oversized calls raise ValueError without discarding fields or consuming a sequence number.
  • Emission is serialized across threads. Each record is flushed immediately.
  • stream="stderr" is independent of severity. Captured stdout defaults to info; captured stderr defaults to error. Large captured writes are split into records.
  • Logs MUST NOT contain secrets. No automatic secret redaction is provided. The runner withholds server log collection for sensitive executions; authors must still avoid writing secrets to container stdout/stderr.
  • Logs retain sequence, UTC timestamp, stream, message, level, and optional fields. The CLI renders concise lines; --json preserves the full records.

SDK base classes are Inputs and Outputs; singular imports are no longer supported. Rebuild Action images after updating the SDK. Previously published images retain their embedded SDK and can continue executing with their captured contracts.
