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, anderror; explicit logs default toinfo. - 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
ValueErrorwithout 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 toinfo; captured stderr defaults toerror. 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;
--jsonpreserves 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.
